The Sun produces a range of energy which we can only see a small part of as visible white light. Solar panels turn another part, or wavelength, of the light into electricity that can be harnessed. A photovoltaic cell (PV Cell) produces electricity on the principle that electricity will be produced when two semiconductors are exposed to a particular wavelength of light. Groups of PV Cells are linked together to form panels, the bigger the panel and the more cells, the greater the amount of electricity can be produced.
Many people have seen wind turbines at some point or another in their life, but does the average person know how wind turbines work? We hope to answer that question so you will understand what makes wind power such a great alternative energy. The concept behind the wind turbine technology is not that difficult to understand. The wind blows, which turns the turbine blades. These blades are connected to a shaft that turns with the blades, and attaches to a generator which creates electricity and sends it to a sub-station.
