Which energy source is NOT listed in the material as an alternative energy source?

• A. Tidal power
• B. Wind turbines
• C. Solar power
• D. Nuclear power

Answer: (D)

Energy sources that count as alternatives to fossil fuels are typically those that are renewable and come from natural cycles. In the material, tidal power, wind power, and solar power are listed because they rely on natural forces that continually replenish themselves. Nuclear power isn’t included in that list because, while it can provide large amounts of electricity with low operating emissions, it uses a finite fuel and involves radioactive waste and safety considerations, so it’s usually treated as a separate category rather than an “alternative energy source” like the others.
