Less ______ energy is captured on cloudy days.

Less ______ energy is captured on cloudy days.

• A. Wind
• B. Biomass
• C. Water
• D. Solar

Answer: (D)

Less energy from the sun is captured on cloudy days because solar energy depends on sunlight. Cloud cover blocks and scatters sunlight, lowering the irradiance that solar panels can convert to electricity, even though some diffuse light still gets through. Wind, biomass, and hydro rely on wind, organic material, or water flow, not directly on sunlight, so cloudiness doesn’t affect them in the same way. So solar energy capture drops on cloudy days.
