Renewable energy is a type of energy that does not run out or get used up. It comes from sources that are constantly providing new energy, like the sun, the wind, and rivers. Solar and wind energy are two of the most common types of renewable energy. Solar energy is energy from the sun that can be used to light our homes and run our appliances. Wind energy is the energy created by the wind, which can be used to generate electricity. Renewable energy is important because it helps us keep our world clean and safe.
