•Petroleum •coal • wind

• ocean • wave • hydroelectric power

• solar energy.

1. Renewable => Renewable sources of energy are

Those that can be replenished. Therefore Wind; Ocean; Wave; Solar; Hydroelectric power are renewable sources of energy because they can be reproduced and they do not cause pollution.

2. Non - renewable=> Non-Renewable sources of energy are

Those that cannot be reproduced. Therefore Petroleum; Coal are non-renewable sources of energy. Also they cause environmental pollution.

3. Green Energy sources => All the energy produced from the renewable sources of energy belongs to green energy. Therefore Solar; Wind; Wave; Ocean; Hydroelectric power are green energy. Also they do not cause pollution.
