Which of these features is true of both solar and wind power?
A
They both produce energy only during the night.
B
They both require fossil fuels to generate electricity.
C
They both have a constant energy output regardless of weather conditions.
D
They both rely on renewable energy sources.
Verified step by step guidance1
Identify the key characteristics of solar and wind power: both are renewable energy sources, meaning they are naturally replenished and have a lower environmental impact compared to fossil fuels.
Understand that solar power relies on sunlight to generate electricity, which means it is not available during the night unless stored in batteries.
Recognize that wind power depends on wind conditions, which can vary, affecting the consistency of energy output.
Acknowledge that neither solar nor wind power requires fossil fuels to generate electricity, as they harness natural resources directly.
Conclude that the common feature of both solar and wind power is their reliance on renewable energy sources, making them sustainable options for electricity generation.
