Which energy type is renewable?

Which energy type is renewable?

• A. Solar energy
• B. Coal energy
• C. Oil energy
• D. Natural gas

Answer: (A)

Renewable energy comes from sources that replenish naturally within a human lifetime. Solar energy fits this because the sun continuously emits vast amounts of energy, and we can capture it with solar panels or other technologies. The key idea is that the supply is effectively inexhaustible for our purposes, unlike fossil fuels which are finite and formed from ancient organic matter over millions of years. When burned, coal, oil, and natural gas release energy but deplete finite reservoirs and contribute greenhouse gases. So among the options, solar energy is the renewable choice.
