There are two sources of energy: renewable and nonrenewable. Nonrenewable sources are fossil fuels – coal, natural gas and petroleum. Once these natural resources are used up, they are gone forever. Renewable sources of energy can be used over and over again. This includes solar energy, wind, geothermal energy, biomass and hydropower.
