Question

fossil fuels account for approximately what percent of energy used in the united states? 100 15 80 5

Explanation:

To determine the percentage of energy from fossil fuels in the US, we rely on energy statistics. Fossil fuels (coal, oil, natural gas) dominate US energy use, with around 80% coming from them. 100% is impossible (other energy sources exist), 15% and 5% are too low for fossil fuels' major role.

Answer:

C. 80 (assuming the options are labeled A:100, B:15, C:80, D:5; if labels differ, adjust to the option with 80)
