FOSSIL FUELS
The sun’s energy is stored in coal, natural gas, water and wind. Coal, oil and natural gas are known as fossil fuels. Fossil fuels were formed over millions of years when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans.
We use the energy in these fossils fuels to make electricity. We use electricity in many different ways. We light and heat our homes, schools and businesses using electricity, and to run computers, refrigerators, washing machines and air conditioners. Our cars and planes run on gasoline, which comes from oil. As of the year 2013, most of the energy we use comes from fossil fuels.
