Answer 2

Hydropower is definitely not it, that is a renewable energy source that doesn't waste any resources. Never heard of volcanic power being used as an energy source. It's definitely not geothermal, because that has to do with Earth's energy, which is pretty infinite. It has to be natural gas. That uses it up and is currently a huge problem. That's why "hybrid" cars are being made so we can save gas, a dwindling natural resource.

Answer 3

Still very unsure. :( Thank you though.

Answer 4

I'm 100% positive it's natural gas. That uses up natural gas, which is a nonrenewable resource.
