One of the solutions is the use of clean and renewable energies. Renewable energy does not deplete natural resources and does not cause any damage to the environment. There are many types of renewable energy, including bioenergy, wind energy, hydroelectricity, solar energy and geothermal energy. Bioenergy is produced from trees and plants like corn and soybeans, which are harvested to produce energy in the form of biofuel. Wind energy is created by wind turbines, which convert kinetic energy into mechanical energy, then ultimately converted into electricity. The only downside to wind power is that it causes noise pollution. Solar energy captures energy from the sun. Hydroelectricity is produced by the gravitational force of falling or flowing water. Many dams around the world are also used to produce hydroelectricity. Geothermal energy is produced by the Earth's internal melting
