Atmospheric Madrid pollution levels

Since the coming into force of the Kyoto Protocol, countries of the European Union, including Spain, made a lot of plans that seek to reduce the emission of gaseous pollutants, something that can be reduced to a level tiny if you take the necessary steps and be maintained this trend can be achieved to improve air quality significantly.




Regarding the city of Madrid, is placing emphasis on an innovative Surveillance network whose last regulatory and effectiveness was launched on November 11, 2009 although it is the fruit of decades of work and the combination with last generation technologies made available for the care of the environment.


One of the first signs of concern over pollution and the air monitoring was in 1968, where the air monitoring activities carried out and planned continuous analysis of the atmospheric conditions in the city of Madrid, despite the fact that technology that was not then so specific that they used samplers.
Ten years passed until settled completely a provision of sensors distributed throughout the city, which ran in joint automatically, creating a certain amount of fixed stations which remain until today, but with the necessary technological updates.

Adopted the directive on May 21, 2008, were established new patterns in the measurement of the air, a criterion of unification of measurements, to introduce the need to balance stations placed at sites with excessive traffic, and those that are more isolated.

Since then, the stations fixed updated constantly, to the level achieved today, where accessible public form to all the information regarding the air quality and the protection of the atmosphere, in addition to the different measurements that are published on a daily basis.


Madrid boasts the so-called Comprehensive air quality system, whose purpose is to advertise on a daily basis the levels of air pollution , according to the regulations in force, and seeks to have a constant update of a dedicated website, where can we find that listed below:

In each index referred to the major pollutants and indicates the different levels in the air.

What are alternative energies?

All Over the world, is now an alarmingly high rate energy used free due to the rapid industrialisation and increased awareness among consumers. Most of the world's present energy is generated by fossil fuels, which are having disastrous effects on the environment on a global, local and regional levels.

Fossil fuels such as coal, natural gas and oil are used to create more than two thirds of our electricity and almost all of our fuels for transport. Our fossil fuel reserves are diminishing quickly to meet the increasing demand of energy and also their use is becoming more expensive by the day. Not only that, the burning of fossil fuels causes global warming of the Earth and release of many harmful green house gases in our atmosphere at a very high rate.

The term "alternative energy" has become a bit of a catchy phrase these days. People use this term usually but they would have completely different ideas of just what it means. As mentioned above, most of the energy produced in the world today comes from the fossil fuels such as coal, oil or natural gas. The simplest meaning of the term "alternative energy/renewable energy/green energy is energy from a renewable or green source (other than fossil fuels).

Alternative energies are energies generated and used in a way that promote or are compatible with long-term human well-being and ecological balance. Alternative energy or renewable energy turning out commercially viable for a growing list of consumers and used. Alternative energy technologies offer many advantages and are suitable for the General sustainable development i.e. the development of the economy, the environment and social welfare.
Renewable/alternative energy is the energy from natural processes that are often supplemented. Most renewable energy sources are environmentally friendly and combat global warming by reducing carbon emissions and also allow the economies to their dependencies on politically turbulent Nations to curtail. Renewable energy is generated from solar energy, wind, rain, tidal, hydropower, biomass, geothermal sources, biofuels and hydrogen.

If you're tired of your electricity bill ever are rising and you don't want to waste more money on your electric bill or you want to help the global economy and save the Earth ... you have here the solution. With the ever increasing cost of living, there is no better time to stop throwing money and begin to create renewable energy for your home itself ... the best choices for generating renewable energy for homes are solar energy, wind and micro-hydro energy generation. Following sections will explain these options in much detail with benefits to give you a good heads-up in case you are interested in the generation of energy from alternative sources for your homes.

U.S. Geothermal Energy


Renewable energy development aims not only to care for the environment, but also the replacement of a nonrenewable resource such as fossil fuels, which in a indefinite period (and not so far) will be exhausted or will have a greater demand the amount harvested, so that one of the various ways to replace it with geothermal energy.

Geothermal energy

On this occasion, we discuss how to prepare the country for U.S. exploitation of this energy source, with the promise that in the not too distant future, be able to replace coal as much as 10 times the performance, and of course, far less polluting .


The first step has been undertaken for such production began with the development of so-called Geothermal Energy Map, which is already available to access Google Earth (clicking through this link) and displays perfectly the resource variables geothermal distributed throughout the United States.

This had been a pilot with the launch last year of a map of geothermal energy to West Virginia, in addition to planning the development of sources of abstraction and a progressive replacement of thermal power plants that dominate the energy production in the area .
What is Geothermal Energy?

For those who do not know what it's about geothermal energy, then we leave some videos describing seek to clarify all your doubts:

Aston Martin Cygnet




The market of vehicles is preparing to give a qualitative leap in the field of clean energy, with the presentation not only of a broad platform of electric cars, but also to the development of electric bikes, opening the way to what many manufacturers have planned for 2012, as a dramatic change in the mobility and autonomy.


On this occasion, we have encountered with the presentation of a car that in addition to being free of carbon dioxide emissions, it has been carried out by a prestigious firm specializing from the outset in the creation of luxury cars, and that is recognized worldwide for being the choice of Agent 007.

In this way we have before us the long-awaited aston martin cygnet, an electric car that has been announced years ago, and that approaching its release date we can see its final, as well as some light details about design of their benefits.

In principle, it would use a pack of Lithium Ion batteries that allow you, with a full load, a close to the 100 kmrange, considering that this Coupe will have performance of a sports car as the firm we are accustomed.

Garbage collecting trucks



Surely some careful reader will be thinking that there are of a drafting error in the title of this article, but the truth is that it has been successfully written, since it is a surprising developments of recent days renewable energy.


The problem of waste generated on a daily basis might fix in the future, since in the city of Toronto (Canada) is working to develop a new engine that uses fuel energy from various wastes.

This would not be anything new (many are working on it) if not because it seeks to apply nothing more and nothing less than in a truck, garbage collection, which would have a kind of integrated processing of biogas unit and can extract it and use it to propel himself.

The engine is already finished and this would be a Cummins Westport ISL G (already equipped in some vehicles that use this fuel) and what I would be remiss is generate a means which can extract the biogas debris and injected into the impeller.


Different prototypes are being built at the moment and perhaps, in the future, we can see on the streets of our city to one of these trucks "mobilize itself"

Filter sand water



We have already seen the different water filters that are present in the household to produce drinking water either to improve the quality of it, eliminating the presence of substances that may be harmful to health, or to improve the taste, although there are also other more sophisticated filters that are used for the treatment of waste water and for the preparation of the waters that will come to the homes.


The most used of these is the so-called Sand filter, used as a method of separation of solid particles that are suspended in the water, using different layers of sand with different sizes (dimensions of each grain) which is passed the body of water.

While it does not have the same success as other methods and more specific systems (such as the Coal asset, which helps eliminate chlorine) the implementation of this filtering is essential to separate heavy metals and the presence of iron in water, through a process of chemical reactions by looking for the precipitation of the same.

When the filter was with their process, to maintenance mode is an investment in the flow of the water, changing the sense and favoring the cleaning of the system, which means a much cheaper alternative to begin the process of purification , despite having large and require a strong initial investment for construction.

If you want to let us present your products, catalogs and announcements, we have advertising space to ensure that they reach all our readers.

Google increases its commitment to the renewable solar thermal



Recently Google has announced that it will be a very important investment in a project of solar thermal energy. They are 168 million dollars, which constitutes its greatest economic bet on renewable energy, adding to the time the figure of $ 250 million.



The project in question is the Solar thermal power of Brightsource Energy's Ivanpah plant in the Desert of Majave, in the southwest of United States. The plant will have an installed capacity of 392 MW and is expected to be completed by 2013.

It will be composed of 173.000 heliostats of two mirrors that reflect and concentrate solar energy in the central tower. There the heat produces steam that will move the turbine, generating electricity.

At the same time, Google is working on the technological development of mirrors more efficient to enable future to reduce the costs of solar thermal.

The Pitcher filter

Between the different types of water filters that we have analyzed many of these systems are attached directly to the tap, or used in the treatment of residual waters, although in recent years, and taking advantage of the principle of Activated carbon, has been the emergence of the so-called mugs with filter, which we will explain below.



These systems are completely external to the network of drinking water, and work not only as a simple jar for storing and cooling water, but that also notoriously improve you the taste, applying the above filter with Active coal system that is responsible for removing the chlorine present in the water due to the process of purification.

The main advantage is obviously that the installation of a device or modify the tap water is not necessary, and work practically in the same way, as well as generate economic savings for water free chlorine.

The disadvantage is that they require a periodic replacement of cartridge with activated charcoal, which tends to be in many cases exclusive to a given mark, and generate a spending of periodic money, taking into account that these spare parts are provided by the manufacturer.

Another of so many variables to get optimal quality water and without the need for profound changes in the home.

Low consumption appliances

Low consumption appliances are those which, to a certain task - consume the least amount of energy possible. Sometimes also used to refer to them otherwise is as efficient appliances, energy efficiency is not anything other than a higher performance with less energy expenditure.




The label energy is our best ally to recognize household appliances of low consumption. It's a warning that comes in the vast majority of household appliances, or at least those that require more energy :
refrigerators and freezers washer dryers, washer-dryers dishwashers domestic lamps electric furnace air conditioning.
The Energy label indicates how much these devices consume energy . The label shows the category of efficiency of the product in the following way:
The letter A is for teams more efficient (also indicated in green). These are the so-called low consumption appliances. Knowledge to the improvement of efficiency which implemented some brands are distinguished the low power consumption as A +, to ++ and to +++ (this being the best efficiency).
Then the level of efficiency goes down, passing through B, C, D, E, F and up the letter G used to less efficient teams (in this case using the color red). With the advance of the energy efficiency programs these past levels must go disappearing market, until that they are only released low consumption appliances.

Buying a low-power appliance is - clear is - the first step to saving energy and, consequently, a not inconsiderable amount of money on your electric bill. But to make it truly happen also we must use them correctly and be attentive to the basic Tips for saving energy.Here are some recommendations of the idea in this regard:

Do not buy appliances most large or more power than we need. Check the manufacturer's instructions must be staying and cleaning the apparatus to prolong his life and save more energy. Air conditioning should be located at 26 ° C in summer (not lower). Turn off completely teams with information at digital window or displays (televisions, audio, etc.) with when we are not using them. At the sites of the House where the light stays lit for more than one hour a day placed low consumption lamps or fluorescent tubes.

Apart from these fairly general tips, it is advisable address in detail the recommendations of energy saving for each type of electrical appliances in particular. So in Erenovable we have been preparing some special articles to guide you in this task. Here you will find a guide to saving energy in various situations:

Surculus by Nick Squires: sprinkler life to your garden




Keeping and caring for a garden are a full time job. And above all, if one maintains a grass, should be very careful and irrigation times are very important. If the supplied water is lower, the grass is dry. If it is too much, there is no record of water which can lead to the destruction of root hairs. An intelligent and optimal, sprinkler is an ideal way to meet the water needs of grass and Surculus is better than possibly dreamed of at an economical price.


The Surculus is a sprinkler system of water that uses a Li-ion battery to power itself. This battery gets charged through solar energy and the best part is that the sprayer can be controlled remotely, wirelessly. The design of bulb is beautiful and elegant. It is simple and aesthetic. All necessary controls are placed at the top for easy access. The controls have also kept at a minimum, making it easy to handle and use the Surculus.
In the top right is a timer that you can define to distribute water to given intervals of time. It is knowledge of gardening that is the best time for water in 5 grass. Instead the lifting early, you can only set the timer and sleep peacefully. Controls at the top are protected by a cap twistable.

Right under controls, run by the Centre are two tubes. One of the tubes is home wiring and cabling as necessary to connect the battery with solar panel with the timer. Another tube is used to remove water to dispense. Depending on the measure that opens the tap, the force of the water is controlled is dispersed.
The Surculus is easy to move and place in different locations on the lawn. It has three peaks long act as legs. These ensure that it gets planted firmly on the lawn. The base of the inner body area has been designed with a height that did not come into contact with the grass where it is located. This ensures that there are no points dead on the grass where the base touched the turf.

It is solar energy, the sprinkler becomes another 'green' object in your garden. A project of the "design week", organized by the University of Derby, the Surculus was the son of the 2nd year students brain. Stands testimony to creative minds, working for a 'green' cause really can provoke wonderful transformations and change.

Green homes programme

It green homes program is to provide, to all those who want to follow him, advice and recommendations to save water and electricity, using the car more efficiently, learn how to Recycle in the proper way, learn about composting and so full of possibilities.

Because what he really wants is to promote self-control of the domestic consumption of water and energy in a simple way, introducing little little steps and saving behaviors involving no more than a simple change in the way of life. In this way, a more ethical and more responsible purchase will not be as an effort but will be as something automatic, standardised.



The green homes program lasts a full year, and he often participate families and/or young people who want to learn how to lead a life more healthy and supportive environment.
These programs are carried out in various cities and municipalities of Spain as Las Rozas (Madrid), Ciudad Real, Toledo, Badajoz, Galicia, Tenerife, Valencia Community… Among other cities struggling to be solidarity.
But if it is not possible to register in your city or town hall, you can always follow the councils that are providing green home blog or that we have in Erenovables.
Do you know that we are we, citizens, responsible for 30% of energy consumption and 10 per cent of the total water in our country?
With these figures, the green homes program aims to raise awareness of the importance of these duties so that little by little people make an use more sustainable and solidarity of all those resources which are collective.
Otherwise, for many more compelling approach to it, is that through these changes in consumption can Save money and resources.



In our hand is helping to make life possible now and many years to pollution reduction, that everyone can enjoy a water cleaner and less polluted.

Because when one begins to make small changes, we are achieved when the great.
To finish the post today, I would like to leave you a I proverbio facing the green agenda that seems truly significant blog:

"Changing the world, gives three laps around your House" (Chinese proverb)

Fuel liquid electric cars



This is a year of transition to a broad platform of electric cars that will be released next year, according to various announcements and releases of major manufacturers in the world of the engine,
although they are also developing various candidates to replace oil, which can be combined with this form of mobility.


On this occasion, the news is that a new technology that would use fluid to recharge the batteries energy-feed the electric motors, which would have up to 10 times higher in comparison to other chemical batteryperformance is developing.

The application of these would be designed to replace the batteries of cars today, generally using Lithium Ion batteries, which would significantly increase their autonomy and would also facilitate their replacement, its size is naturally lower.

These batteries can be recharged through a process of emptying and filling, with subsequent collection of the electrolytes that are processed to be reusable, so it would be a practically inexhaustible source of resources.

This innovative project was an important initial investment of 1.2 million dollars of the project, and has been sponsored by the New York State Energy Research Development Authority (NYSERDA).


The energy of the building system draws a solid oxide (SOFC) fuel cell UTC Power of 400 Kw. The SOFC are used for the production of energy on a large scale and work on the basis of cogeneration of heat and power (CHP). This type of battery fuel requires a very high temperature (700-100 degrees Celsius) to produce electricity. This requirement of high temperature creates a problem, but the steam produced by the high temperature can be used to produce more electricity.


It is fuelled by natural gas that turns into electricity through an electrochemical process constant that requires less than combustion and thus produces less emissions.

Germany to abandon the Nuclear energy

The nuclear disaster in the central Fukushima with its devastating results, at least we are leaving something important: the growing awareness of the urgent need to abandon nuclear energy.

And this awareness reached, fortunately, Germany, one of the most important economies of Europe. His coalition Government to decided to close all nuclear plants abroad for 2022.




Germany currently has a total of 17 nuclear power plants that generate about one quarter of total energy needs. Among them, there are seven reactors - the more old-already given low after safety inspections carried out after the disaster at Fukushima. The remaining will be deactivated in the next 11 years, advancing significantly the date before scheduled to its closure in 2034.

The generation of electricity that now perform the German nuclear power plants will be replaced by renewable energy sources: mainly energy wind, solar and hydro (which today produce about 17 percent of the electricity). It is expected that to achieve the year 2022 already are producing 50% of the energy needs of Germany.

Garoña Nuclear

The ghost of what happened in the fukushima Central continues to cause havoc around the world, and the alarm broke out in each region where there is a nuclear reactor, taking as examples in Spain the numerous incidents of the Ascó Nuclear power plant, which has the watchful eyes of numerous activists and monitoring bodies.


Central Nuclear Garonya


On this occasion, the call to attention has been raised by Ecologists in action, but not referred to this plant, but the precarious situation facing Garoña Nuclear power plant (Burgos), also joined in an incident which forced them to put a stop unscheduled activities.


This has been motivated because of an incident produced on May 26, when performed manoeuvres of recharge, putting in place the turbines and noticing some abnormal and excessive vibration, encouraging emerging as desist implementation underway.


This flaw can lead to a rupture of the turbines affected, later producing a leak of radioactive steam, which by the disposition of this plant, can be quickly distributed not only by the building auxiliary, but also towards the environment.


The request is that this plant stops working until 2013, when the final cessation of its activities, had planned to avoid further incidents, or that some inevitable happen and endanger the security.

Alternative energy

Alternative energy is energy which can be extended and the Sun, wind, waves, or other natural sources. This is in contrast to that is obtained by fossil fuels such as oil, gas or coal which is not renewable energy. Alternative energy is a non-traditional method of obtaining energy that a minimal impact on the environment of the Earth. Alternative energy is, by its nature, economic easy on the environment and does not have a harmful effect on the planet.

Due to record high gas prices and increasing concerns over the health of the planet and the long-term viability of fossil fuels, alternative energy is thrust to the forefront of many peoples thoughts. Many companies and individuals are looking for effective ways to use alternative energy and reducing our dependence on foreign oil and fuel. There are many fears that the current supply of fossil fuels will not last, lead to a disaster of catastrophic proportions. Alternative energy is the key to becoming a more self-sufficient and independent as a nation, as the only way to ensure the safety of the planet and the long term health of its citizens.

There are many different sources of alternative energy that can be used very effectively. Produces energy from geothermal energy using heat from beneath the surface of the Earth and collect heat from the atmosphere or oceans. Most use a process called flash steam. Solar energy turnover sunlight into energy using photovoltaic panels. There are many experts across the country that these panels to convert sunlight into usable energy is another source of renewable energy for alternative energy is wind energy wind is caused by the uneven heating of the surface of the Earth by the Sun can install.

This energy of the wind energy equipment using wind turbines convert wind energy in a usable energy source. Wave power is another method of alternative energy that the ocean surface waves to generate electricity, and also to desalination water used. Wave power can not be used simply everywhere but there are several places around the world who are excellent sources of wave energy including North of Canada, the coasts of Western Scotland, South Africa, Australia and the northwest coast of the United States.

Alternative energy is widely available and has become in recent years very user-friendly. It is a viable way for a person to be more self sufficient while doing their own side to minimize the pressure on the Earth, as well as the depletion of fossil fuels to reduce and eliminate our reliance on foreign countries for our energy needs.

Advice - Why Convert To an Alternate Energy Source and Be Part of the Global Warming Solution

Alternative energy sources are renewable and are thought to be "free" energy sources. Realizing that oil is finite in practical terms, there is increasing attention given to what alternative energy sources are available to replace oil. What is one reason why these are needed?


What are currently being used in the us? Due to increasing global consumption and the probable depletion of the world's non-renewable energy sources, ways of exploring and using these are under study. these are a desirable way to produce electricity because they do not create air pollution, and serve to diversify the sources of America's electricity, the majority of which is currently produced through the burning of coal. Although these are just beginning to attract mainstream attention, decades of research and study have provided various degrees of hassle-free options with invaluable long-term effects.


At the same time, they are being viewed more and more as a worthwhile insurance policy against the risk of depending on the middle east and other unstable regions for the bulk of the world's oil and gas supply. Research is needed now more than ever because oil and other nonrenewable energy sources will run out in the near future. These are abundant - and renewable. As a result, resources are adopted as a solution for this problem.


In sum, these are far better in every respect nuclear power simply does not stack up. The most important is that they are not currently viable. Since many these are "clean" in both production and in their use, they could also be a factor in resolving the issue of environmental racism. Many are gaining popularity in homes and businesses.


Not all green energy is equal. These are not all created equally and many still have a significant carbon footprint from their manufacture, installation or use. It amazes me now that push has finally gone to shove all these advances in these are springing up. These are being widely explored. We are running out of natural resources which need to be preserved, so they are necessary to deal with this. This article will provide you insights and you will find out what the top five of these are.


Before we learn what the five alternative energy sources are, it is important to know what these alternatives really are and how they help. You are probably asking the question; what these are there out there for me? Consequently, many are adopted as a answer for this problem. Due to increasing global energy consumption and the probable depletion of the world's non-renewable energy source, ways of exploring and using these are being undertaken.


These five alternative energy sources are just a few of the many alternatives to fossil fuels. Alternative resources are mostly anything to do with energy from nature. Oil and natural gas are cheap now and the economics of these are questionable at best. These are now seen as more than ideas they're now tangible options.


In conclusion, all this talk of big money and countries and investments is all well and important, but what about you and I Keep your eye in the tabloids for the cheap construction for your home Life is good and with technology getting better each day.

Alternative Energy For the Home - Cheap, Reliable Energy

There is a growing trend towards homes hat are being powered by alternative energy sources from solar panels to wind turbines and from hydrogen fuel cells to biomass. Building your own power generation system is becoming easier and more cost effective than purchasing these systems pre-built and as a result more and more homes are taking advantage of the technology and saving money.


There is a massive need and desire to become less reliant on fossil fuels and become more independent by manufacturing our own energy, locally. Living off the grid is no longer just about having power when living remotely, but rather about having your own power whilst living in areas that have grid facilities, but not wanting to have to pay large corporations for power that can be generated far cheaper through reliable off grid technology.


When listening to people like Remi Wilkinson, the senior analyst with Carbon Free, it becomes obvious that over the next decade or two, the micro generation of energy through solar panels and wind turbines as well as magnetic generators will begin to cut dramatically into the profit margin of these large corporations. They will have to stand up and take notice of what the average man on the street is doing. Changes in the way corporations run their businesses will have to be implemented.


Remi is part of a group called Carbon Free which studies the growing trend of domestic homes using alternative energy. The trend is picking up momentum due to government recommendations as well as the increase in easy to follow instruction manuals that are available online at extremely reasonable prices. It is also gaining a lot of interest because of the rising cost of oil and other fossil fuels and the huge impact that this has on the environment


Carbon Free have concluded that if prices of energy remain the same or increase in the future, then the increase in homes that take advantage of micro energy generation through wind, solar and magnetic energy devices will be extremely large. They suspect that the transition from fossil fuel use to alternative energy for domestic applications could mimic the transition from library and postal service to the internet for data retrieval in the home. The speed at which that change has taken place could effectively put the large corporations out of the domestic market within just a few decades


While energy companies are trying to find ways to ensure that they do not lose their market share, the internet has facilitated the ability to build your own power generation systems for a fraction of the price of buying them.


Even if you only have rudimentary DIY skills, you can build your own alternative energy device and begin saving money on your electricity bill immediately. Already the components for building these devices are becoming cheaper and easier to locate and many of the companies selling alternative energy devices are finding themselves having to lower their prices to remain competitive. This has resulted in a win-win situation for those willing to take the plunge and go green.

Five most unusual vehicles powered by biofuels


  
Vehicles powered by biofuels Most unusual vehicles powered by biofuels
Today, in a world, where pollution is growing at a fast pace and the fact that all of us face many health problems because of that, we need to urgently find ways to make this world a cleaner and a greener place to live in.

There are so many vehicles running on the roads, each adding their share of pollution. But, as these vehicles have become an inevitable part of our lives, we should find vehicles that are pollution free so that the future generations can live healthier and cleaner lives.

There are already some such engines that do run on bio fuels. Bio fuels are made from natural substances which burn completely without giving out harmful gasses that cause pollution. But, due to economies of scale, bio fuels are more expensive than the usual petrol and diesel.

The other factor against bio-fuels is that their energy content is lesser than conventional fuels. None-the-less, efforts are being made, the world over, to make the bio-fuels more viable and the vehicles more popular, for a better future for all.

Here is a list of five some unusual vehicles powered by bio-fuels:
1. Biodiesel Hummers

 Biodiesel HummersThese cars are the same as Hummers usually are, but they run on biodiesel
These cars are the same as Hummers usually are. But, the catch is, that they run on biodiesel, fuel that is made from decomposed plants.

The fuel when used gives out the least amount of pollution making the vehicle completely eco-friendly. Biodiesel Hummers are the ultimate replacement for the usual gasoline ones and are slowly becoming really popular among Hummer lovers. The biodiesel Hummer gives a mileage of 19 mpg and you can also get your gasoline Hummer converted to a biodiesel one.

2. Hybrid vehicles



 Hybrid vehiclesThese vehicles use two sources of fuel
These vehicles use two sources of fuel. One of them being a conventional source like petrol and the other being the eco-friendly one, that is electricity. By using electricity, a part of the emissions of the vehicle are completely harmless. These vehicles, thus have a higher mileage as well. These vehicles have an internal combustion engine and an electric one.

There is a long list of hybrid vehicles that exist today. From scooters, bicycles, mopeds to heavy vehicles like trains, ships, aircraft and even cranes, all come in the hybrid form. A new form of hybrid vehicles is the human-powered electric form.

This includes electric bicycles and electric skateboards, etc. There are also a range of passenger vehicles that are now coming in the hybrid form. Most of the passenger car makers are coming up with newer varieties of hybrid with improved technologies. These vehicles are pollution free, but the cost of fuel is a bit of a concern in this case as well.

3. Electric cars with nanotechnology batteries



 Electric cars with nanotechnology batteriesThe advantage of nanotechnology batteries is that they are very light in weight and take very less time to recharge

The advantage of nanotechnology batteries is that they are very light in weight and take very less time to recharge. They also, are more durable and therefore last longer.

Engines running on these types of batteries boast of zero emissions! Moreover, according to some studies, Nano Lithium-X battery technology has the best output of energy as compared to other technologies available. Nanotechnology offers higher rates of battery charging and more energy supply as compared to other eco-friendly sources of energy.

4. Green races




 Green racesAn example of this was Audi which won a race with its bio-diesel powered car
Since road races are a rage among race lovers, we also need to find ways to have eco-friendly races for a cleaner future.

An example of this was Audi which won a race with its bio-diesel powered car. Efforts are being made by the organizers of these events to reduce their carbon footprints and introduce more vehicles that run on bio-fuels, to the racing track.

5. Travel to the green way


Travel to the green way Successful prior experiences of bio-fuels with jets and fast cars, bio-fuels do give a ray of hope in this arena as well

Alternative rocket fuels are being devised to help us reach space in a greener way. As the outer space is light years apart, this is much easier to talk about than made a reality. Although, with successful prior experiences of bio-fuels with jets and fast cars, bio-fuels do give a ray of hope in this arena as well. We can now confidently say that bio-fuels will surely work well to give energy to spaceships. The use of rocket fuel, which is inevitable today may not be so in the future.

The harmful emissions of this fuel should be done away with, as soon as possible. As going to outer space, now-a-days, is a regular phenomenon, we surely need to work on bio-fuels as a reliable source for rockets as well.

With so many new vehicles running on bio-fuels and newer ones being worked on, we can surely expect a greener future for the world.

2012 International year of sustainable energy



Good news, no doubt, is for those who are in favour of the growth of renewable energy as a means for sustainable development. But certainly this "gesture" of the UN will not be a solution to the serious problems arising worldwide from the use of fossil fuels, it will be a good opportunity to bring more attention and point to awareness.

Why the UN choose this theme for the year 2012. One of the reasons pointing to the concept of energy as a means for the improvement of the quality of life of many (many) people around the world. In this regard, emphasize the social aspects of sustainable energy access.

The energy increases the productivity of farmers, helping to alleviate the scourge of hunger. Energy illuminates the learning on the way to reduce the high rates of illiteracy. Energy relieves the burden of work on millions of girls and women. Energy saves the life of sick children. Energy allows to modernize diagnosis systems, helping to prevent diseases or better care of children and pregnant women. Energy gives the operating rooms, giving doctors the power to heal and save lives. Energy enables communication and the improvement of life in thousands of previously isolated communities energy opens bridges to the future and helps equip opportunities.


While the benefits of sustainable energy that we have described just seem very encouraging, reality unfortunately far from take this to the majority of the people.
In the presentation of the project, the United Nations published very worrying statistics do not if corroborate the huge disparity in our world.

Approximately between 1400 and 1500 million (21 per cent of the world's population) has no access to modern energy . 3 billion people (40% of the population) depend of the « traditionalbiomass » or coal as a source of energy. At the same time, in countries with energy systems, millions of low-income people cannot access them by inability to pay this service.

The big leap to incorporate these masses of people to the possibility of electrical energy is a priority. But it is important to note that the energy must be sustainable. I.e., their production and their use must not harm to the environment or the communities. For this reason, the response to this need is renewable energy.
Renewable energy is inexhaustible, put in feeds on natural resources - as its name - you you renew: wind, solar, wave, geothermal sources, etc. It does not generate pollution in the process of generation.
And here do not complete the benefits...

It is more economical in the long term, and does not require mega investment as it required for a nuclear power plant or a thermoelectric power station. It does not require a network to work, since it can be generated independently in each community and each House. And is more secure (only remember Fukushima).

In short, is the energy of the future… a future we must build.

LED lights

One of the technologies is becoming popular in recent times, which also has the advantage of developing the same light capacity than a conventional bulb, but with significantly lower electricity consumption helping to save it and up to the possibility of using renewable energies.



Technology of LED lights is characterized by leveraging a diode, semiconductor, item conditions i.e., one that can behave as a conductor of electricity, or simply as an insulating the same passage in different circumstances (inferred from an incident, radiation up to a given temperature).

The LED designation means Light-Emitting Diode (in English, light-emitting diode) and evidence that a diode is used to generate an effect of luminescence with the encouragement of an electric current by emitting light at a wavelength of reduced spectrum.


This luminous colors are directly dependent on the material that has been manufactured LED, those who are in the range of the visible spectrum, although there are also LED with capacity to emit a light UV (ultraviolet), or those that emit infrared light, also known as IRED (Infra Red Emitting Diode, infrared emission diode) to be used

The latter have been extremely popular and quite used something Homestyle, and many will have probably noticed: are located on the remote control, and are responsible for that work correctly, with a sink in the appropriate device.


They are present in TVs, air conditioning and even attended mobile phones with the IRDA port data, now replaced by Bluetooth, senior benefits technology.

The white light LED development has allowed that they replace light bulbs progressively taking first greater acceptance in the world of cars, including where applicable with varied designs, providing a striking touch.

In the case of the LED screens, used both monitors and TVs, which are used are an enormous amount of LED lights color Green, red and blue, to provide a higher quality image with a high level of contrast, also offer a much higher resistance to shock and vibration.

Machines hybrid



So many times I have talked about hybrid cars.. Since holes bring to a story on hybrid machines. It's a solution very beneficial for the heavy machinery - which has a high level of consumption of fossil fuels-applying similar technology the of other hybrid vehicles, with results of up to 50% of energy savings.


Researchers of Aalto University in Finland have experimented with internal combustion machines , turning them into hybrid vehicles by the addition of electric power transmission systems. They started from the basis that these machines - for the same work - produce an important power generation: either in the slowdown, or activities such as drilling, for example.

Then what they did was ensure that the energy generated by these activities is stored in a battery connected to the own vehicle. This stored energy is later used for the operation of the vehicle, reducing fuel use up to 50%. Also, unused stored energy can be transferred to the network and have an alternative use.

LifeBook Leaf laptop with solar energy

To further promote its acceptance and that is applied to a multitude of Gadgets, Energy photovoltaic technology in a course of necessary expansion, and on this occasion, is applied to a conceptual computer with solar energy that can be used everywhere with ease and extended autonomy.


It's the portable lifebook leaf, which uses a quite practical design, equipped with a touch screen OLED that can be used in Tablet PC mode or as if it were a Laptop (a concept which is being worked too much today)

In terms of connectivity, it would employ a support for 4 G networks, and would include a small panel OLED for basic functions, and notify the arrival of a new message when the computer is closed, or while it is recharging.

But the important thing about this team is that in all its casing is a photovoltaic solar panel that will allow recharging your batteries during its use as when is just in hibernation mode, expanding their autonomy to a previously unattainable level.

The application of clean energy and technology continues its evolutionary course, with concepts and prototypes of the most innovative.

O2 Pursuit

Energy sources that has limited applications is compressed air, mostly known to propel projectiles, precisely, compressed air rifles, although in recent times it is seeking to use this way to take advantage of the air for other purposes, trying to renewable energy.

The news that has come the web in recent days is the presentation of the o2 pursuit, motorcycle using the same principles as these weapons using a carafe of compressed air for a small engine this motorcycle.
Does not have great autonomy, and it is mostly intended to be a vehicle that moved us from work to home, although it is not to belittle the idea of using compressed air on a motorcycle in recent times where seeks to implement clean energy regarding mobility.

The engine has been designed by signing EngineAir, from Melbourne, and whose model carries the designation Di pietro air engine, with the aforementioned container of easy removal for recharging, have the advantage of having a low weight, compared to an internal combustion engine that affects not only the maneuverability, but to adapt the bike to all types of terrain.

At the moment is not more than a prototype that will form the basis for a more developed model and that could well be part of roads in the morning, if the idea is feasible and is accompanied by a sustainable platform.

Knob filter

There are different types of water filters that are used everyday in homes for the sake of improving the quality of drinking water that comes from the water network, which many times is often contain remains from substances or the process of purification, or those that are specific to the tributary of which was obtained prior to the treatment water.


There are filters that use mechanical principles, derived from the physical chemistry, others that Act separating substances by chemical reactions, the so-called Activated carbon which uses a micro-porous rock of carbon and others that simply used a combination of systems, although they often go online in a way parallel to the tap, and not direct.

That is why he considers as the filter for taps as a group apart, because that is a kind of cartridge that is inserted as a mouthpiece in the same or parallel to its mouth, using the previously mentioned and with varied technologies systems to carry drinking water to the highest possible quality.

The purpose of it depends on the type of filter that is used, so there are various costs and features, always thinking of versatility with its quick and easy disconnection also helps a lot when it comes to the maintenance and replacement.

Hydrogen from ethanol and solar energy

One of forms of energy more development is having in recent times is the energy of the hydrogen, applied mostly in the field of cars and other vehicles, and using concepts from other clean energy, as it is photosynthesis, which has been popularized in the field of thesolar.


Energia Solar


On this occasion, we have encountered with a technological breakthrough that was driven by students of the University of Catalonia, in conjunction with other researchers of the University of Aberdeen (Scotland) and the University of Auckland (New Zealand) which seeks to harness this energy source more efficiently.


To get electricity through this raw, it is a huge amount of energy required (to produce the chemical reaction) and so they have resorted to the solar energy as a means of obtaining it, mixing it with a Photocatalyst.


This product is placed in a container of titanium dioxide (semi-conductor materials) together with an unknown quantity ofethanol, being stimulated radiation of ultraviolet light (sunlight filtered) which begins to stimulate the mixture to produce hydrogen, which are later captured by nanoparticles of gold ions.

LEDs used to cure babies with jaundice

Much we talked about in Erenovable the advantages of lights LEDs. Light emitting diode not only consume less energy, emit more light than the compact fluorescent lamps without using mercury. But not only that: the LEDs are also used to help the babies that are born jaundice, a serious disease that can lead to brain damage and death if it is not properly.

image

A device called D-rev brilliance that is used to apply phototherapy with blue light, was used for the first time in a unit of neonatal intensive care in ogbomoso, Nigeria. The baby had been diagnosed with severe jaundice and needed a blood transfusion to prevent brain damage or death. But due to the low weight of the baby at birth we opted for the phototherapytreatment. After a night in an incubator under Brilliance began the recovery without the need for transfusion.

D-rev, the company of California makes that device Brilliance is working to bring this technology - as indeed in much cheaper than other devices in phototherapy- communities with extreme requirements in various developing countries, to enable the processing of the jaundice. This condition - if it detected in time - can be treated with 2-3 just days after the blue light in the baby's skin.

Rechargeable batteries with spring

The constant use of different portable devices has as disadvantage the logical exhaustion of the rechargeable batteries given that autonomy, so often is necessary we look how long a full charge of acquiring one, either ease that possess the recharging time.

To solve two problems in one is that this auto-recargable battery, which can be extended almost eternal shaped autonomy of our devices, inspired by the operation of ancient clocks to rope that they decorate and adorn the walls of the houses has been presented with Japanese designers or some toys that using similar mechanism obtained their mobility (cars to friction, for example)

Its interior contains a spiral spring connecting to a mini-generador that begins to rotate generating energy to recharge the Nickel hydride metallic, material found in a lot of batteries and have the necessary electrical energy that our devices continue to function.

To sum up its operation, simply we must turn its mechanism in a time shift in order to compress the spring, which will launch its mechanism of clock which in turn starts to operate your generator.

Recycling of plastic bags

Much we talked about on our blogs the need to address the problem of plastic bags so much damage caused to the environment.. Today we will stop over in detail to meet one of the possible ways for solution: recycling.





They plastic bags are composed of a material thermoplastic, i.e., a material that is capable of being repeatedly ablandado by applying heat and then hardens to cool down. Therefore it can be recycled.
Let's see what happens with plastic bags since we left them in the containers for recycling:

First, separate the bags of other types of plastics that will follow a different process. Then usually do a quality control of the material. A check of the material is also performed to see if it is contaminated with waste from food. In that case derived you in first step to a "cleaning process".

 The next step is to melt the plastic. The softened plastic is forced through an extruder. What would this be? then something similar to what happens in mass games for children, that they pass through a kind of "sieve" and then leave as if it were spaghetti.  Then gives way to the plastic before being cut with a blade. The final result obtained generally are a few small pieces or balls of plastic, which are then used in the manufacture of other plastic products.

Something important to take into account is the basic rule of the "3 R", according to her, recycling is only a part of the solution. What is crucial is to reduce and Recycle.

When we talk about reducing the idea is to avoid as much as possible, the use, delivery, or the purchase of these bags. Some practical suggestions so that we can lower the amount of plastic bags:
Search for other types of bags or equivalents that are not disposable. For example, bags of cloth or rope, baskets, baskets or boxes.

If you have a plastic bag her not tire after the first use. Use this as many times as possible. For example, use them to store food, for storing clothing or other objects.  Once broken bag (in fact not often resist much) make sure that it will not dump, and instead leave it in the container for plastic recycling. 

Something important to keep in mind is that there are two different types of plastic bags, according to the type of material of which they are composed: 1. HDPE plastic bags - high density polyethylene. They are the thinner bags. These bags are in most cases aptar for recycling.

2. plastic LDPE bags - low-density polyethylene. They are thicker bags, which are usually not suitable for recycling.


Another good alternative is to use bags of plastic biodegradable.

The Top 2 Renewable Alternative Energy Sources

Many countries across the globe are beginning to make a serious effort to locate and use the best alternative energy sources. It is everyone's responsibility to try and lessen pollutants that cause greenhouse gasses.
Alternative energy sources include the use of renewable energy which goes a long way to helping to reduce the number of toxins. Toxins will always be present as they are the by-product of energy consumptions but, there are ways to greatly reduce the concentration of these toxins.

The great thing about renewable alternative energy sources is that we find them abundantly in nature and their conversion into energy typically has little negative impact on the environment. None of them are perfect and certainly their use in and of themselves does involve some waste generation. The creation of toxins however, is non-existent.
What a great alternative energy source these are because their use also preserves the natural resources for other people to use again as sources of energy.

Here are the top 2 popular renewable energy sources.
Solar Energy
The sun will last billion of more years and our ability to gather its energy into solar cells provides us with an unlimited source of readily available energy. The sun's heat is converted into electricity without the use of burning carbon-based fuel such as oil and coal. Large solar farms have many solar thermal panels that follow the sun. Other energy gathering devices include parabolic mirrors. Both these techniques gather the heat and convert to power that heats air or water. The heating of water is used to produce steam which then provides the heat or drives generators for electricity.

Many buildings in cooler climates have adapted their heating systems to take advantage of window exposures to heat and cool the buildings. At first the windows were fitted with solar shades to help keep the room temperature steady as the sun would instantly overheat a room. Now these solar shades have been adapted to collect the heat and turn it into usable energy throughout the building.
The unfortunate side of solar energy is the limitation to daytime operations and times when it is not raining or excessively cloudy.

Wind Energy
Becoming more popular recently is the tactic to harness wind for energy. This type of power generation goes back to before the 15th century when ships and windmills used the wind to produce energy. The biggest drawback was the inefficiency of converting this type of alternative energy. Like solar power the use of this energy source also was entirely dependent on Mother Nature.
The use of windmills throughout history is well documented and they used wind energy to enable the mechanical machinery to perform labor intensive activities. These activities included pumping of water from wells and crushing grains for food production. Modern windmills have boosted the efficiency of the older model from the addition of a wind turbine. The wind still turns the blades which now create energy through the turbine to produce electricity. It is this electrical generator that now powers the mechanical machinery to perform the tasks.

As with solar energy large scale wind farms have been built in strategic locations to convert wind currents into clean alternative energy. These wind farms concentrate the energy into large generators that distribute the electricity through the national power grids. Smaller scale wind farms in rural areas may use the energy generated from smaller turbines for local use on the farm or small community.

While many proponents claim wind power generation has no pollution by-products and is not harmful, the full understanding of the impact on wildlife from the ultrasonic pulses generated from larger wind farms is not fully known. Wind mills do pose a documented danger to the bird population. It is, however, a renewable alternative energy source of which that we will never run out.

The ecological footprint

The ecological footprint is an indicator of the environmental impact generated by humans. Crudely, it is the effect we are producing on land based on inadequate, disrespectful and extreme exploitation of its resources.




The ecological footprint is expressed as the surface needed to produce the resources consumed by an average of a certain human community citizen, as well as the necessary to absorb the waste generated, regardless of the location of these areas.
We exploit the fields, forests, the sea... without leaving a space of time so you can regenerate itself, we do not give an only rest to land above the respect it is own economic good.

The calculation of the ecological footprint is based on the impact that makes each mode or way of life, i.e. communities of human on the planet by comparing it with its capacity.

This calculation is based on:
Certain materials and energy, as all existing products, have their origin in ecological systems are needed to produce any product.In turn, become need ecological systems to reabsorbed waste that we have created to obtain our product or to use it.Later, fill all infrastructures that occupy the space needed for productive ecosystems.The calculation of the ecological footprint is complex and its data are often underestimated the real impact of human activity by the lack of available information.


Here, we show you the data from the calculation of the ecological footprint that took place in a study of 2003 at the global level (Semarnat, 2007)

In it you can see which activities are those more ecological footprint have generated in the population. To understand the result, keep in mind that have spoken earlier, the bases of calculation:
47.5% Burning fossil fuels22.0% agriculture7.6% wood, pulp and paper.6.7% Fishing6.3% livestock3.6% Nuclear energy3.6% urban settlements2.7% LeñaLa obtaining ecological footprint has made it possible to compare two completely different worlds under one common denominator, its impact to the environment. It allows us to see two closely related realities:

The first observation allows us to see the way of life of the rich countries of the planet can not to expand to the rest of its inhabitants.

While the second, if we talk in terms of sustainable global economy, the wealthy minority would have to reduce their consumption and their standard of living because there would be no sufficient planet that everyone lived as a well-off European citizen because of the exploitation of the resources based on the availability of fossil fuels.

That leaves us in conclusion, that the much of the developed countries ecological footprint exceeds exorbitant way its own surface, given the resources and discharges of waste extraction in places far removed from its territory.
