Then you also have to account for losses in drilling oil, shipping it to a refinery, refining it into gasoline or diesel, shipping it to a distribution hub, then to a gas station. And all the electricity consumed in doing that. And the navy and coast guard ships that need to patrol all the oceans to keep the oil tankers safe. And...

replyBuilding power stations is a one-time cost. If the power station is solar or wind, same thing, only no fuel. Not the case for fossil fuels.
replySolar panels or windmills are like oil drills. They aren't oil.
