Which statement best describes fossil fuels?

• A. They are renewable energy sources
• B. They include coal, oil, and natural gas
• C. They are formed by solar energy
• D. They are never used for electricity generation

Answer: (B)

Fossil fuels are nonrenewable energy sources formed from ancient organic matter under heat and pressure over long periods. The energy they contain originally came from the sun, captured by ancient plants and organisms, but the process that turns that matter into coal, oil, and natural gas is geological and takes millions of years. The most direct and accurate description is that fossil fuels include coal, oil, and natural gas. They are widely used to generate electricity and to power transportation, so saying they’re never used for electricity is false. They’re not renewable, and while the sun’s energy is the original source, simply saying they’re formed by solar energy doesn’t capture the long geological formation process.
