Well, your showerthought post was basically rich people cause suffering and climate change. It's true they generate a hugely disproportionate amount of CO2. But my point (and maybe it wasn't clear) was that when there is an easy energy resource just sitting underground, it's going to get used whether by rich people or not. It provides too much of an advantage. Having coal and oil at your disposal is like having a near endless supply of free workers. One liter of gasoline, when used in an engine, produces roughly 2 to 4 kWh of mechanical energy, equivalent to the daily labor of about 100 people. No society is going to turn down that many guiltless slave workers. We were told 100 years ago it was going to cause climate change, but we didn't have the technology to replace it with electric at the time. Effective batteries are a recent invention. So there really was no alternative. Your neighbor country is making use of millions of 'energy slaves' and growing their population like crazy. Are you going to continue plowing your fields with donkeys and hoping you can feed your people? No, using that energy was inevitable.

And now? Theoretically we could replace our energy infrastructure with renewables. In the US it would take at least 5 trillion dollars and who knows how long and how much energy to do it. But I don't think it'll stop climate change. Call me a doomer, but I think it's already too late for that. We've already released enough CO2 to kill the planet. The effects just take about ten years or more to show.
