What are alternate energy sources? How can you personally use them?
Some alternate energy sources are solar, wind power, and geothermal. Solar energy can be used to run cars, power plants, and space ships. Wind power can be used to turn windmills. Air can help us breathe fresh air. Withut air Earth would be dry and breathless. One of the other energy resources is geothermal. This energy source can be used to help water from boiling at 100 degrees celsius, whish is enough to boil water to run a steam-powered electric powerplant.
