Search " alternative energy " is the effort made in the entire world . There are many government agencies , universities and scientists around the world are working to find ways to replace conventional fossil fuels with the latest environmentally friendly energy . Most people agree that from now on people should start saving energy and natural resources reduce our dependence on non - renewable fossil fuels such as coal , petroleum and natural gas . This alternative form once assumed to be paid back by the nuclear powers . Alternative power is considered as the answer to our global energy problem .
A large amount of power that can be generated from a small amount of uranium is viewed as a power source for the future of our planet because of the nuclear generating clean power with no contribution to global warming . But as we know , such as fossil fuels , uranium is also a limited natural resource that over time will run out .
Alternative power generally refers to non - traditional fuels that do not burn fossil fuels or use of any natural resources that will result in damage or harm to the environment . In other words " Alternative Energy " is the power that is cleaner and environmentally friendly .
This alternative source provides many advantages and benefits over fossil fuel use more traditional like the least pollution and fuel costs are cheaper , but the drawback is that these alternative sources are not always available when we need it because sometimes the wind does not blow or the sun does not shine . But the existence of the modern technology available today can make use of the full power of this alternative when it is available .
So let's look at some alternative power sources are the most common and see how these alternative resources work . The strength of Earth's sun always provide a source of heat and light . Simply put , solar power is energy radiation coming from the sun and by using several different methods we can transform sunlight into electricity using the power of photovoltaic solar cells . Photovoltaic cells generate alternative commonly known as the " Solar Power " .
Pollution this solar energy could be virtually non-existent from the source , the sun . This principle works by using solar thermal energy to heat water or thermal conductive liquids such as oil flows through a series of thermal conducting metal pipe covered in a reflective solar panels or plates . We often see the roof of the house using the power of the sun to heat water , but the solar energy can also be used in solar pool heating system to help heat a large amount of cold water in the outdoor pool without swimming pool electric heating units are expensive . Pool heating using flat plate collectors can also increase the recreational use of the outdoor swimming pool for up to four months during the year just uses free power from the sun .
