Renewable energy – what they are and how to use them
As our planet increases rapidly to a looming energy crisis, we must end our dependence on fossil fuels and non-renewable energy sources as soon as possible. As their name implies, non-renewable energy sources, which can not be replaced, and if used, they are gone forever. Renewable energy sources with never exhausted. The three main sources of renewable energy solutions, solar energy, hydropower and wind power. But what is it and how can we benefit from it?
Solar energy: Solar energy is the most abundant source of energy available on Earth. It is not only free, in many parts of the world, but is also very abundant. Where possible you should take advantage of this fantastic source of free energy. There are many solar energy solutions today that can be applied easily at home. Not only will this help to reduce energy costs, but can also enable a greener world contributes .. clean solar energy solutions are composed of solar cookers, solar systems, solar lighting, solar dryers, etc.
Besides being very cost effective and environmentally friendly solar systems have many other advantages. They are low maintenance and saves time and effort. You can also get a great return on investment in a short amount of time. This means that after a short period of time, the system will have paid for itself, and will continue to be fully free energy for a long time after.
Hydro–electricity: water or hydropower is a very efficient source of renewable energy. Although they are usually produced on an industrial scale, are now small hydroelectric plants are available for the use of this renewable energy source. E ‘was estimated that 90 percent of electricity from renewable sources is generated exclusively from hydropower. With large hydroelectric dams built systems to generate electricity from a water column, which, when released, has sparked a huge amount of energy that can be converted into electrical energy by large turbines.
There have been some concerns about the use of these hydroelectric, because large systems can destroy large areas of natural habitat when they turned on the lakes.
Wind energy: wind turbines have been used for thousands of years for a variety of applications. They helped tow boats and pump water and grind grain into flour. At times in recent years, they have become a source of electrical energy.
Windmills, large and small have proven to be extremely effective cheaply in large quantities of electrical energy. When used in a smaller scale, you can actually often completely replace conventional energy sources. An excellent source of renewable energy, wind energy will go a long way, promises a good future ahead of future generations.
