In recent years, the electricity generation mix in the western United States has shifted from fossil fuels and nuclear power to nonhydro
renewables. In the eastern part of the United States, generation has shifted primarily from coal to natural gas. Texas has seen a growth
in generation from both coal and nonhydro renewables.
