The parabolic trough is the leading solar thermal electric technology used today. It focuses sunlight on a tub carrying a heat-absorbing fluid, such as oil. This fluid circulates through a boiler where its heat is used to boil water to steam which is routed to a turbine to generate electricity. Wind Wind systems use large blades mounted on tall towers. The wind spins the blades rotating a generator that produces electricity.
Wind turbines can stand alone or be part of large wind farms.
Many people don't like the way they look, they can be noisy and unless special care is taken to design wind turbines to protect birds, birds can fly into the blades and be killed. The purpose of this project is to demonstrate that PV is a viable candidate for large scale electricity production. PV power conversion uses direct conversion of the sun's radiation into electricity, by using cells made of Silicon, the second most abundant material on earth. Currently, bulk power generation for use in residences and industries is through use of coal, oil, gas. Hydro power generation is also being utilized in many places.
