> Annual maintenance cost for the US T&D grid is $40 billion. We're talking "increase it by a factor of 10” You quoted $2300bn to replace the transmission and distribution system, you say you’d need to increase the $40bn maintenance figure tenfold to replace the grid, but $400bn a year would mean doing that in five and half years. In reality whatever increases turn out to be needed have to happen over thirty to forty years. And of course doubling demand would be accompanied by huge extra revenues, the electricity system takes in on the order of $400bn a year, doubling the unit production of electricity would mean $12tn of extra revenues, $24tn in total revenues over a 30 year timescale, relative to this it’s difficult to see how $2tn of extra costs on its own can mean a doubling in electricity rates, as you suggest.
