Renewable energy sources are ones which don't run out-which can be renew ed. We can keep using them and using them, and we'll never run out. Examples of renewable sources include wind, water power (hydroelectric), and solar power (light from the sun). Non-renewable energy sources are ones which do run out.As we use them to generate energy, they get used up, and can't be used a second time.ssentially, the difference between renewable and non-renewable energy is that renewable energy can be used over and over again. Whereas, non-renewable energy is energy that cannot be used again once it is used.
