California pays the 13th-lowest grid electricity bills per capita in the US despite having the 2nd-highest electricity price. Texas pays the 38th-lowest bills per capital (21% higher than CA) despite half the electricity price as CA. Why, because TX consumes 2.5x the electricity per person as CA.

Just to clarify my position on massive datacenters. I made a bold statement that large AI datacenters would peak within 5 years for many reasons, chief among then that AI will probably be mostly done locally. So we'll not likely see less electricity going to compute, just less centralized compute.

I wouldn't be surprised if the Iranian War is the best thing to ever happen to RE. Bottom line: gas infrastructure (like nuclear) cannot survive the new age of drone warfare. In fact any centralized grid will most likely not survive the age of drone warfare. Localized solar, wind, batteries can.
