Over the past 100 years, the amount of energy used in the United States and else where has greatly increased. Today, a number of energy sources are available, such as coal, oil, natural gas,
nuclear energy, hydroelectric power, wind, and solar energy. Some of these energy sources are being used up and are nonrenewable, but others are replaced as fast as they are used and, therefore,
are renewable. Some energy sources are so vast that human usage has almost no effect on the amount available. These energy sources are inexhaustible.
Think about the types of energy you use at home and school every day. In this activity, you will investigate how and where energy is produced, and how it gets to you. You will also investigate
alternative ways energy can be produced, and whether these sources are renewable, nonrenewable, or inexhaustible.
