With fossil fuels, you don’t need to input energy to get them. At least not in the same way. You can run a pump to pump them out of the ground. For each unit of energy that goes into the pump, you likely get 1000x units of energy out.
- _aavaa_ 3y agoI get what you mean. That will really depend on where you get the oil from. Some places need a lot more downstream processing (looking at alberta oil sands) to get something useable than others (the middle east). Whether you want to consider that analogous to the electrolysis step or to another one is not clear since the processes don't map one to one.
