Is solar energy renewable or nonrenewable?

• A. Renewable
• B. Nonrenewable
• C. Nuclear
• D. Fossil Fuel

Answer: (A)

Solar energy is renewable because it relies on the sun, a source that will keep shining for billions of years. Each day the sun exists with a vast, essentially endless amount of energy, and using it to generate electricity or heat does not deplete that source on human timescales. Once solar technology captures that energy, it can be used repeatedly without running out. The main point to note is that solar output can vary with day-night cycles and weather, but this variability doesn’t make it nonrenewable; it just affects when energy is available and is usually addressed with storage and diverse energy sources. By contrast, fossil fuels and uranium-based nuclear energy depend on finite resources, which is why they’re categorized as nonrenewable. So solar energy is renewable.
