Which statement best defines alternative energy?

• A. Energy from sources other than traditional fossil fuels, such as hydro or solar.
• B. Energy from fossil fuels only.
• C. Energy produced by nuclear weapons.
• D. Energy stored in batteries for later use.

Answer: (A)

Alternative energy means energy from sources other than traditional fossil fuels, such as hydro or solar. This captures the idea of using options beyond coal, oil, and natural gas to power our needs, including water, sun, wind, and other renewables. The other statements don’t fit because energy from fossil fuels only isn’t alternative at all, energy produced by nuclear weapons isn’t a practical or civilian energy source, and energy stored in batteries is energy storage, not a source of energy generation.
