BECAUSE OF ALTERNATIVE ENERGY

The main energy resources we use (coal, oil, natural gas and uranium) are limited and, therefore, can be depleted. Furthermore, their use results in a significant environmental impact on the biosphere by polluting the air, water and soil.  

These facts have generated a growing interest in the development of new technologies for the use of alternative renewable energy sources that are currently unprofitable but have the advantage of being less polluting.

The present, in our country, alternative energies represent only about 1.5% of energy production

The development of human society is based on the consumption of large amounts of energy. The energy flows through ecosystems and provides a livelihood for living things ultimately comes from the sun. 

However, despite the scientific and technological development, we have yet to learned to effectively harness this inexhaustible and therefore most of the energy we use comes from the natural resources on our planet, mainly coal and oil.

New Type of Bladeless Wind Turbine Can Be Twice as Efficient Without Being a Danger to Birds

When it comes to the future of wind power, a company thinks of cost savings and efficiency. So in Tunisia has created a new technology called Zero-Blade.

But what's that Zero-Blade technology? The knives are replaced by a shaped candle body while gearbox hub and are removed, thereby increasing the efficiency of existing devices for converting wind power.

According to the company an average wind turbine capture only 30 or 40%, while the turbine is said Saphon 2.3 times more efficient. Additionally, the expected cost reduction of 45% less than a conventional turbine, mainly due to the fact that there is no sheet, bucket, and no gearbox units.

The most important of the Zero-Blade is energy storage. Most of the kinetic energy can be stored (through a hydraulic accumulator) or can be converted into electricity with a hydraulic motor and a generator. "We have developed several prototypes.  

We are in our second-generation prototype. We did the test and the second is twice as efficient as a three-bladed turbine in terms of production is at least 50% cheaper. "Said Hassine Labaied, one of its creators.

Photovoltaic Solar Energy

It is increasingly common to see solar panels on the field, especially in sunny areas and begin to appear in homes, but We know it works? Renewables now try to show what lies beneath.

The photovoltaic solar energy is a type of renewable energy that comes from the sun's rays to produce electricity through the photovoltaic effect that is often used for different purposes such as appliances, isolated houses or go directly to distribution networks.

The two main applications given on photovoltaic solar energy is directed to:

     Photovoltaic solar energy directed at isolated installations the power grid is composed of solar panels that capture solar rays, and this energy is stored in batteries. This allows us to enjoy electricity in places that sometimes are inaccessible to the network such as mountain huts, lighting, cottages, etc..
 
     On the opposite side are photovoltaic systems connected to the network consisting of the same process for the production of energy with the difference of application, in which it is sent to the electricity grid.

Did you know that electric distribution companies in Spain are obliged by law to purchase the energy produced by solar power?

The photovoltaic power plants are one of our options when it comes to enhance and increase the consumption of solar energy to proliferate ever more strongly renewable energy.

It's about time that both the utilities and the general public begins to see solar energy not only as a possibility that now seems out of reach financially but as a cost-effective long-term goals and issues such as environment, economy and quality of life.


  

Biogas: alternative fuel gas

 As we already saw on a previous occasion, the biomass includes fast-growing plants, remains of animals, wood and algae cultured, to cite just a few simple examples.

It is a source of energy from the Sun ultimately, and it can become renewable energy provided be used properly



What is biogas?

The biogas comes to be a fuel gas generated in specific devices or natural environments from the different reactions of biodegradation plaguing the organic, by the action of micro-organisms as well as other factors in the absence of air.

This resulting gas consists of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and other gases although in quantities smaller than the previous ones.

What can biogas be used?

The production of biogas by decomposition without air (anaerobic decomposition) is a useful way to treat biodegradable waste, given that produces a fuel value and generates an effluent that can be applied as a soil conditioner or generic payment.

In addition, this type of gas can be also used to produce electricity via turbines or generating plants to gas, as well as stoves, dryers, furnaces, boilers, or other combustion gas systems.

Alternative Energy - Wind

In the world that we live in today that consumes fossil fuel like it does water, it is no wonder that we are soon going to live in lack of what it is we know as our only source of energy. All we need to do is look for alternative energy to serve us for a long while, if not for life; with wind mill, solar and the rest we are going to do ourselves a lot of good.

What a lot of us still don't know, is that we you can set up a alternative energy in the form of windmill in less time than it used to be in the past and it has grown popular amongst nations the world over, with new home owners setting up alternative energy as a source of power for their homes, cutting on bills and setting up a new environmentally fresh world that will allow a good life for the human race.

Truly it is possible to cut down on your charges on electrical bill if you install an alternative energy source like the wind mill in your home to power all appliances, come to think of it a whole lot of people from diverse part of the world are doing the same today.

More so a visit to countries that are popular in the usage of wind power are the likes of Denmark and the Scotland were almost every energy need generation plan depends on at least a source from the energy of the win.

As it may seem hard to get up a wind energy plan, it would become less hard if you can just ask someone who has done so in the past for information that may elude you before now.

Better still you can take the plunge and follow the link herewith below this piece to take you by hand and mind into the mind bugling world of alternative energy, you need to know that with insights enough to motivate you to start something today.

While you never have to wait any longer for solutions to your energy needs. Sure you will also cut bill cost or take the challenge and tell your power distributing company to keep their cables for someone else.

Investments in Alternative Energy

It is possible to have a portfolio which profitably (that's the key word, is it not?) invests in alternative energy funds. “Green” energy production is expected to be a multi-billion (in today's dollars) industry by 2013. The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient as well as more widespread. More state-of-the-art wind energy technologies are typically more market competitive with conventional energy technologies. The newer wind-power technologies don't even kill birds like in days of old! Wind energy production is a growing technology, and companies engaged in it would make up an excellent part of a growth or aggressive growth portfolio. Next to consider are solar cell, or photovoltaic cell, technologies. These are to be found implemented in pocket calculators, private property lights, US Coast Guard buoys, and other areas. More and more they find their way onto the roofs of housing and commercial buildings and building complexes. Cost is falling. Their energy efficiency (the ratio of the amount of work needed to cause their energy production versus the actual energy production) is steadily on the rise. As an example, the conversion efficiency of silicon cells has increased from a mere four percent in 1982 to over 20% for the latest technologies. Photovoltaic cells create absolute zero pollution as they are generating electrical power. However, photovoltaic cellls are not presently as cost effective as “utility produced” electricity. “PV” cells are not [capable at present for producing industrial-production amounts of electricity due to their present constraints on space. However, areas where photovoltaic cell arrays could be implemented are increasingly available. In sum, costs are going down while efficiency is rising for this alternative fuel technology. Many alternative energy investment portfolio advisors are confident that alternative energies derived from currents, tidal movement, and temperature differentials are poised to become a new and predominant form of clean energy. The French are actually fairly advanced at hydro power generation, and numerous studies are being made in Scotland and the US along these sames lines. Some concerns center around the problems with the deterioration of metals in salt water, marine growth such as barnacles, and violent storms which have all been disruptions to energy production in the past. However, these problems for the most part seem to be cured through the use of different, better materials. Ocean-produced energy has a huge advantage because the timing of ocean currents and waves are well understood and reliable. Investments in hydro-electric technology have grown in the last two decades. Hydro-electric power is clean; however, it's also limited by geography. While already prominent as power generation, the large, older dams have had problems with disturbing marine life. Improvements have been made on those dams in order to protect marine life, but these improvements have been expensive. Consequently, more attention is now being paid to low-impact "run-of-the-river" hydro-power plants, which do not have these ecological problems. The reality is, the energy future is green, and investors would do well to put their money out wisely, with that advice in their minds.
