Solar power could have their future in the colder regions of the plane

When ordering someone to mention the geographical area privileged for solar power generation, it is common thinking in the warm deserts, there where are some of the of the world's largest solar farms. However, surprisingly, a new study concludes that some of the landscapes more cold in the world - including the Himalayas, the Andes mountains and up the icy lands of Antarctica- could become the next "Saudi Arabia" of solar energy.

The research in question appears in ACS Environmental Science & Technologymagazine and was in charge of Kotaro Kawajiri and his team of colleagues. These scientists explain that the potential for generation of electricity with renewable solar energy depends largely on the geographic location to install a solar power plant. And arid and semi-arid, zones with much Sun and long time exposure have been recognized as good places for these purposes. So far, nothing new.

However, the scientists point out that, as a result of the scarcity of available data at the global level related to how influences the climate, there are still gaps in the knowledge of the best geographical locations for the production of solar energy. To extend that knowledge, they developed a technique that allows them to estimate the global potential of solar energy with the data that are available today.
The technique takes into account the effects of temperature on performance of solar cells. In the next stages of this study are also considered other variables, such as the losses during the transmission and impact of snowfall.

As it was expected, found that many of the hot regions, such as the Southwest Desert EE.UU., are ideal places for the installation of large conglomerates of solar panels. However, he also found that many cooler regions that are located on a high-altitude receive a significant amount of light solar.
So much so that in these high mountain areas, the potential to produce solar power is even greater than in some desert areas. Kawajiri and his colleagues found, for example, to the Himalayan mountains (including Mount Everest) could be an ideal place to install solar farms which could generate much electricity for the economy in rapid expansion of the People's Republic of China.

Other areas that were potentially promising for solar power generation in cold conditions were the mountains of the Cordillera de los Andes and even the cold - indeed - frozen land of Antarctica. We will have to see what conclusions get futures and most exhaustive analysis to be carried out to adjust the model, and above all, what says the reality in live, beyond theory.

The Planet is in Danger-Alternative Energy is our Only Choice

When we talk about alternative energy, we are referring to alternatives to fossil fuels. Alternative energy sources would ideally be extended for an indefinite time. The environment is constantly being harmed by the use of fossil fuels and the future damage, including the huge increase in greenhouse gases, is something which we must all be made aware of. Alternative energy sources would not be the environment in any way, making them safer for the planet, and creating a much, much cleaner option.

Alternative energy would be self supporting, never run out, never to be expensive and easily available to everyone. It's only a matter of time before the big energy companies a more environmentally friendly attitude and actively involved in the search for alternative energy sources.

The options under discussion today are wind, solar, hydropower, biomass energy, geothermal energy and even tidal power. While some of these options a visible impact on the environment, the overall effect is a negative as there will be no damage to the environment.

Many of these options have used for small scale, for many years. Wind energy in Netherlands to drive wind turbines. Hydropower Station water mills to such things as flour, and more.

Today we are accustomed to solar energy panels take light from the Sun and convert it into energy that our homes will produce heat, hot water and more. Solar energy is also used in places such as swimming pools. This alternative energy source is deployed by relates to the swimming pool that gather the light, convert, and help to keep the water warm.

In many parts of the world that geothermal energy is used to heat houses. In Greenland, most houses heated by geothermal energy. Although most geothermal sites are located near volcanic regions, some not. This source of alternative energy is completely renewable and cheap to produce.

Another source is tidal power. I use this title to cover tides, rivers and dams. Dams have one-way traffic. Water is, in principle, stored behind the massive walls and may be carried out through their systems huge turbines that produce massive amounts of renewable electricity that we all use every day driving. Tidal energy is usually two directions. Construction of a Dam in a river or estuary, turbines or Alternators built into the design. They produce power when the tide goes out, and produces power when the tide goes.

There is a lack of power production on both bottom and top tides, called slack tide, but this alternative energy source is already successfully used in many countries around the world, and a proposed Severn Estuary barrier is soon to be built near my house in Barry in South Wales, UK., produce enough alternative energy to power a whole cityday in-day out, forever while the tides run.

These are just some of the many sources under discussion today. All of these alternative energy options must be explored and perfected and in very, very shortly we will use or, if we haven't already done so, irreparable damage to the environment. I wonder what my children, and their children from us in the future in the neighbourhood of thinking will. Will they curse or bless us? It is up to us. It is up to us today.
