The issue is: Texas is anti clean energy and blames its problem on the "Green Deal" which it doesn't adopt.
Tesla has the ability to help Texas to avoid the blackout but how do you convince the leaders there?
Texas loves green energy. The grid is 2/3 coal and natural gas, with the rest as renewables (including "nukuler"). I'm paying extra for Austin Energy's "Green Choice" that supplies all my power from renewables and charges the appropriate rates to build out and maintain that infrastructure. The "combustion" electricity rates fluctuate with market prices.
The 2011 Texas grid failures (and the ones 10 year before that) were brief and mildly inconvenient. Both times a post-mortem report indicated "hey y'all, we need to winterize" but by then the political conversation had moved on and the will to spend was gone.
This time is different. I know some people going on 72+ hours without power with sub-freezing temps the whole time. Millions are impacted. Businesses are hurt. People have died. Now the water is running out and we're getting boil notices (without power, lol). Nobody is letting this go anytime soon.
And sure, Tesla can help. Renewables were never going to be able to entirely power the grid until large-scale storage was practical. But this is not a
capacity problem per se, it's a lack of disaster planning.
