Renewable and Nonrenewable Energy

Energy sources power our homes, schools, and vehicles. Some energy sources are renewable — they replenish naturally and will not run out. Others are nonrenewable — they exist in limited amounts and take millions of years to form, so once used they cannot be replaced quickly.

1Define renewable and nonrenewable energy sources
2Match energy sources to their renewable or nonrenewable label and a real-life example
3Explain why switching to renewable energy is important for the environment
