Renewable energy.

 

There are many sources of energy, some get reduce after use of it and some did not get reduce after use of it. Source which does not get reduce is source of renewable energy. Renewable energy sources are tides, wave, flowing water, sunlight and wind. Turbines helps to capture energy of water and winds. Electrical generator is connected with turbines so that when turbines starts rotating, function of generator starts. There are two main ways to change sunlight or solar energy into electricity. One is used to convert water into steam to drive turbine by mirrors to concentrate solar energy and to magnify it's heating effect. Electricity is generated directly by photovoltaic cell by facing them to direction of sunlight. Two layers of silicone mergs to form a photovoltaic cell. One layer receives electron emited by the other layer. Where the two layers meets, sunlight makes electron to move out of atom there by creating positive and negative particles. As this difference is created, one layer attract positive particles and other layer attract negative particles. Electrons are neutrally attracted to protons, but to collect them again electrons must flow through external circuit and get back to layer of cell by creating charge. This cell keeps generating electricity as long as light falls on it.
