Solar energy
What is it.
every hour the sun beams onto earth more than enough energy to satisfy global energy needs for an entire year. solar energy is technology used to harness the suns energy and make it usable. many people are familiar with so-called photo-voltaic cells or solar panels.
On a much larger scale, solar thermal power plants employ various techniques to concentrate the suns energy as a heat source. the heat is then used to boil water to drive a steam turbine that generates electricity in much the same fashion as coal and nuclear power plants, supplying electricity for thousands of people.
