your mission Your mission is to investigate how oil and coal are used as energy sources Right now fossil fuels including oil and coal provide more than 80 percent of the energy used in the United States People use oil and coal every day to fuel cars and buses create electricity and more Oil and coal supplies are limited But they still have an important role to play in our energy future You need to learn more about these important fuels to understand why How were they formed How do they produce energy What effects do oil and coal have on the environment Review the facts in What You Know to help you with your mission what you know (cid:204) Fossil fuels include coal oil and natural gas (cid:204) Fossil fuels are the remains of plants and animals that died millions of years ago (cid:204) Coal is a black or brown rock made up mostly of carbon Most coal in the United States is used to generate electricity 4
