Renewable energies cause much less pollution compared to fossil fuels, and are usually a lot more efficient. Although initial costs can be higher for renewable energies, operating costs are generally cheap, and they are an environmentally friendly choice. WATER POWER is a renewable source of energy that uses the power of falling water to turn turbines, which produce electricity. This type of energy is also known as hydro power. Although the use of water power does not cause any pollution, building hydroelectric dams is an expensive process that could damage the habitats of certain animals and destroy scenic areas (World Book Energy Supply, n.d.; Planete Energy, n.d.). TIDE POWER is also listed as being one of the energies of the future. It uses the energy from rising and falling tides to generate power.
SOLAR POWER and WIND POWER are forms of energy that are becoming more popular. According to Planete Energy (n.d.), in the case of solar power, panels are used to harness energy from the sun. Wind energy is captured when the wind turns windmills, which generate power. Another type of renewable energy is NUCLEAR POWER, created by spitting atomic nuclei and exploiting the energy (World Book Energy Supply, n.d.; Planete Energy, n.d.). WOOD and BIOFUELS are two other forms of energy. Wood can be burned to produce heat, while biofuels are created by using the energy from plants.
