Hydroelectric energy is one of the alternative energy sources. It is a type of electricity produced by generators propelled by the movement of water. Dams block a river to form a reservoir which then collects the pumped water. Releasing the water from the reservoir causes the pressure behind the dam to force water. Nuclear power, as the name implies, is the use of nuclear reactions which generate heat to produce atomic energy. These nuclear reactions could be. Another alternative source of energy to solar power is the use of a fuel gotten through the contemporary process from biomass. Some people often use the words biomass and biofuel. Wind energy is one of the alternative energy sources that's free and renewable. The wind powers wind turbines which in turn generate electricity. It's also traditionally used to do other works like pumping or milling. The. Natural gas is also one of the fossil fuels. It contains mainly methane and a varying amount of higher alkanes.
