Final answer:
Geographical extent and climate are two factors that can affect which sources of energy are used in different areas of the U.S.
Step-by-step explanation:
Two factors that may affect which sources of energy are used in different areas of the U.S. are geographical extent and climate.
Geographical extent plays a role in energy use because large countries like the U.S. require more long-haul transportation of energy resources. For example, regions that are far from coal mines may rely more on other energy sources like natural gas or renewable energy.
Climate also affects energy use as certain areas require more heating or cooling. Cold regions may rely more on heating fuels like natural gas or oil, while warmer regions may use more electricity for air conditioning.
