Describe at least two factors that you think may affect which sources of energy are used in different areas of
the U. S.

In the United States and many other countries, most energy sources for doing work are nonrenewable energy sources:

Petroleum

Hydrocarbon gas liquids

Natural gas

Coal

Nuclear energy

These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels.
