Energía renovable, or renewable energy, refers to energy derived from resources that are naturally replenished on a human timescale. These resources include sunlight, wind, rain, tides, and geothermal heat. Unlike fossil fuels, which are finite and produce greenhouse gas emissions when burned, renewable energy sources are sustainable and have a lower impact on the environment.
The main types of renewable energy include solar power, which harnesses sunlight; wind power, generated by wind turbines; hydropower, produced from flowing water; biomass, derived from organic materials; and geothermal energy, accessed from the Earth’s internal heat.
The use of renewable energy is essential for reducing reliance on non-renewable resources, combating climate change, and promoting energy security and sustainability. Transitioning to renewable energy sources is seen by many as a critical step toward creating a more sustainable future, as they offer a means of delivering energy while minimizing environmental damage and reducing harmful emissions.
