hydroelectric energy is energy from water that is moving can carry large amounts of energy.For hundreds of years,water wheels has been used to grind grain and run machinery.

wind energy comes from moving air.it is created when the sun heats the earth.wind machines can only run when the wind blows about 14 mps or more.wind turbines operate on a simple principle.the energy in the wind turns two or three propeller-like blades around a rotor.the rotor is connected to the main shaft,which spins a generator to create electricity.the

the shallow ground or upper 10 feet of the earth,s surface maintains a nearly constant temperature between 50 and 60 f (10 and 16 c.geothermal energy produce electricity is a very clean process it dose not make pollution.

Biofuels comes from plants it interesting because biofuels come from living materials. plants capture energy from the sun.

Geothermal

Geothermal Energy comes from heat deep under ground.This energy is produced in the core of the Earth.The heat from the core can melt rocks into magma.The steam rotates a turbine that activates a generation, which produces eletricity. Many power plants still use fossil to boil water for steam.Geothermal power plants ,however use steam produced from reservoirs of hot water found a couple of miles or more below the earth's surface.

Fossil fuels come from dead plants and animals.

The heat energy is used to run cars and trains, to warm building , and to produce electricity in power plants.
