ABSTRACT
There are many sources of energy. Fuels are called "fossil" because they were formed from ancient plants and animals. The three basic fossil fuels are coal, oil, and natural gas. Most of the energy we use today comes from these sources. All fossil fuels have one problem: they are gradually getting used up. Water power is energy that comes from the force of falling or fast-flowing water. As water flows from a higher to a lower level, it runs a turbine--a device that turns an electric generator. This is called hydroelectric power. Nuclear power is created by releasing energy stored in the nucleus of an atom. Wind power is a rapidly growing technology that doesn't pollute or get used up like fossil fuels. It depends on windmills and wind turbines. Geothermal energy is heat from the Earth. Biomass energy comes from burning wood and straw (materials known as biomass). Solar power is energy directly from the sun.
