Die. We will die. The only crutch that props up our massive jump from 1 billion pre industrialized society to our current 8 billion human beings on this planet, has been cheap and plentiful fossil fuel. Notably, it is the only thing that has allowed us to practice agriculture on a scale that supports our population growth. When it’s gone, there is nothing to replace it, short of a miracle fusion revolution.
The average carbon cost to produce an electric vehicle is about 6 tons on average, not including the battery, about the same as an ICE vehicle. Where does the energy for auto manufacturing come from? Primarily coal and natural gas, with a sliver of insubstantial wind and nuclear power. About 7 barrels of oil go into each and every tire on the road (between expended energy and actual petroleum products in the tire). Charging the battery? Coal, natural gas, and the same trickle of alternative sources mentioned above.
Speaking of those alternative energy sources, what do we use to make them? Building a nuclear power plant is likely the most carbon intensive process ever devised, from the machinery that moves the earth, to the foundry that makes the steel. As much as I’ve always wanted to believe in a cozy eco future, every time I squint a little I can see that it’s all just a coat of green paint over the same old oil field. The people trying to sell you on oil, and the people trying to sell you on alternatives to it, are doing the same thing. Selling you something. That’s all that matters to them.
There is no feasible alternative that changes the outcome. There is no replacement for what has allowed us to create wonders and horrors beyond our ancestors wildest dreams, and sustain a population far beyond anything we could have achieved without fossil fuels. When oil finally becomes unproductive, so will the mechanisms that hold our current civilization together, and we will wind up back in 1810 if we’re lucky, or 400ad if we aren’t.
Call me a doomer and downvote me or whatever. It doesn’t matter.
