PV Gap

Jose Said:

Which of the following is a non-renewable energy resource?

We Answered:

Your teacher screwed up. They're all renewable. The answer s/he's probably looking for is natural gas. However, any time you have cellulose decompose in the absence of Oxygen you get natural gas. So if wood (not listed) is a renewable energy source then so is natural gas. Also, if s/he is going to baulk at that answer explain that the sun has a finite amount of fuel and will eventually burn out. So technically solar power is not renewable. Wind is generated (ultimately) by the sun. So wind is out too. The sun will eventually go red giant and consume the inner 3 planets... guess hydro is out too. Your teacher didn't spend too much time thinking about this.

I suppose there wouldn't be life to begin with: Plants use solar energy
