Another thing crossed my mind today when I was looking a chart of the breakeven period for BEV. They consume vast amounts of FF during their building and then if run on 'renewables' only pay all that back in a number of years. The number has been getting lower and lower, probably due to many factors including cheaper made Chinese cars. It's touted as around 2 years now but it all depends on how you calculate it. Do you use Dollars, or actual carbon energy units? Either way it struck me that it's just another form of debt. Burning years worth of future fossil fuel consumption now instead of as you go along, as in fueling cars.The amount of renewables required to power the world at its present usage are quite simply multiples of anything we could construct without mining asteroids.
There are years of backlog for the transmission equipment required just for data centres.
Europe will need a four times bigger grid, same for America, India Africa.
Of course the same applies to windmills and solar panels, you're borrowing carbon from future consumption to generate power now. IE: Mountains of coal burnt in China to make the stuff along with all the liquid fuels to mine and process. As well as all the earth moving and construction on site where they are erected. I'm a big fan of Solar, my roof is covered in it, but it's obvious that remote 'farms' are not nearly as efficient as point of generation usage. No construction needed, all mains wiring already in place, and the cost and liability is covered by the homeowner. I feel sorry for people in England and Germany etc, those nations went all in and now the citizens are stuck paying back the loans and interest on it all. Plus I wish people would stop referring to these systems as renewable, they are not, my solar panels have been up for years and there are no new little panels sprouting up there. They are rebuildable systems that run on renewable energy and they need replacing every 20 odd years. Once you get that in perspective it changes the equation.
