Renewables refer to energy sources that are naturally replenished and can be used repeatedly without depleting them. Common types of renewable energy include solar, wind, hydropower, and biomass. These sources harness natural processes, such as sunlight and wind, to generate electricity or heat, making them more sustainable compared to fossil fuels. Using renewables helps reduce greenhouse gas emissions and combat climate change. As technology advances, the efficiency and affordability of renewable energy systems continue to improve, making them increasingly viable options for powering homes, businesses, and transportation. Transitioning to renewables is essential for a sustainable energy future.
