Fuels
You may have noticed that the cost of gasoline has fluctuated over the years. In fact, it reached an all-time high of over four dollars a gallon in 2008. Your car consumes this fuel to produce energy. Finding new sources of oil within the United States, or just off the coast, is an important part of reducing the cost of gasoline since most of the oil we use is purchased from other countries.
Gas is not the only available fuel. Wood is also a fuel. You can burn wood to produce heat energy and to toast marshmallows around the campfire. Basically, a fuel is any substance that is consumed to produce energy. Another type of fuel is called a fossil fuel. Humans burn fossil fuels to produce the energy that powers our vehicles and provides electricity from electric power plants.
