Renewable energy, or clean energy, comes from natural sources that don’t run out, such as solar, wind and hydropower. Less common examples include geothermal energy, which pulls heat from the ground, and bioenergy, which converts organic matter (like algae or crop wastes) into energy.
Generally, harnessing and using renewable energy is less polluting than extracting and burning fossil fuels and coal. In many countries, renewables are also cheaper, more scalable and create more jobs, making their adoption attractive to investors.
