What are renewable energy sources?

Renewable energy sources are defined as energy resources that are naturally replenished over a short time scale, meaning they are sustainable and can be harnessed repeatedly without depleting the Earth's resources. This includes solar energy, wind energy, hydroelectric power, geothermal energy, and biomass. These energy resources are essential for reducing dependence on fossil fuels, minimizing carbon emissions, and combating climate change.

While options discussing energy resources that can only be used once or non-renewable sources like coal and oil correctly define those types of energy, they do not characterize renewable sources. The core property of renewable energy is its ability to regenerate naturally, allowing for ongoing use and contributing to a sustainable energy future. By utilizing renewable sources, we can create a cleaner environmental footprint and promote energy security for the long term.
