As long as there is Sun and air on our planet, there will always be wind!
We might run out of coal, oil and gas, we might run out of nuclear power sources, but we’ll never run out of wind – which makes it a pretty good source for us 🙂 Also, it doesn’t release as many nasty gases!
Like Agnes said, there’s always wind blowing! That energy just goes to waste unless we try and capture it by putting a wind turbine in front of it. Gas, oil, coal and nuclear energy all use something that will eventually run out, and cause a lot of pollution, wind doesn’t.
