Or maybe power grids are teetering because utilities raked in profit for the last two decades by ignoring upgrades that would obviously be necessary...
Just a thought :)
My utility sells $400 Wi-Fi touchscreen thermostats for like $25, the catch being you let them turn your AC down/off when grid load peaks. A few truckloads of thermostats are cheaper than grid upgrades, so they do the thermostats and kick the can down the road more.
World is getting hotter so turn on ac which uses more electricity, build new non-renewable electricity production to keep up which then increases world temps more. We're in a shitty vicious cycle.
