It is a source of energy. Meaning that we can drill for it and then we have it, we don't have to create it. On the other hand hydrogen fuel has energy, but it isn't a source of energy because we can't simply drill for it, instead we have to create it. So while oil is a source of energy, other energy storing compounds like hydrogen fuel are not fuel sources.
Coal oil natural gas
Petroleum energy is energy derived from petroleum products: gasoline, diesel fuel, heating oil, etc.
what is origin of non-renewable energy sources, including how energy became trapped in these souces
Petroleum is cheaper.
No, it is completely different. Petroleum is a fossil fuel

It's the kind of energy that is obtained from burning petroleum products.
the petroleum is used as fuel. it is burned, letting out a burst of energy
