Renewable energy

Renewable energy is also known as "green" energy because, unlike energy created from fossil fuels (coal, oil and gas), it will not run out. Renewable energy uses natural resources that can be replaced or "renewed" without harming the environment and does not contribute to the greenhouse effect and global warming.
