Which energy source relies on sunlight and can be converted into electricity or heat?

• A. Wind Energy
• B. Geothermal Energy
• C. Solar Power
• D. Uranium

Answer: (C)

Sunlight-powered energy is captured and turned into usable power by devices designed to harvest light. Photovoltaic cells in solar panels convert photons from the sun into electricity, while solar thermal systems use concentrated sunlight to heat a fluid and produce heat or steam to drive a turbine. This direct use of sunlight to generate either electricity or heat is what sets solar power apart from other sources. Wind energy relies on moving air to turn turbines, geothermal energy comes from heat stored beneath the Earth’s surface, and uranium powers nuclear reactions to produce energy. Those sources do not depend on sunlight in the same direct way as solar power, which is why the correct choice is solar power.
