Solar Energy for Mother Earth

Solar energy from the sun's heat radiation is just one of the many renewable energy sources that are the subject of current global technological research and development. The harmful effects of the use of petroleum-based fuel to power vehicles and electric generation and distribution plants have prompted governments to take on a more serious look at their energy policies. Aside from solar energy, other renewable energy sources that can be used in lieu of fossil fuel are secondary solar-powered resources such as biomass, hydroelectricity, wave and wind power.

Solar electricity generation from solar power (sunlight) are of two types - by use of heat engines and/or photovoltaics (PVs). Sunlight may be collected onto solar panels which may be used directly as electricity with photovoltaics technology. Photovoltaic cells or solar cells are devices that directly covert light into electrical energy. Concentrated solar power (CSP) systems are heat engines that concentrate or focus large area sunlight, using lenses and mirrors (heliostats) with an installed tracking mechanism to follow and maximise sunlight catch, into a powerful small beam to bring to boil and produce solar hot water used in generating electric power much like that produced from geothermal power plants.
