Renewable energy sources are naturally replenished within a human lifespan.
- Solar energy, harnessed from the sun, is a renewable and clean option, continuously available during daylight.
- Wood is renewable but requires regeneration time, and its combustion produces carbon emissions, making it less clean and efficient than solar energy.
- Coal and Petroleum are finite, non-renewable fossil fuels formed over millions of years. Their use causes environmental pollution and contributes to climate change.
Therefore, Solar energy is the appropriate choice.
