But... but... what about infinite growth??

have you seen the sharp decline of fossil fuel based energy in some locations? The whole point in the necessary move for a battery storage in the long term is to minimize the requirement to boot up gas facilities after work hours, where peak power usage happens and solar is minimum.

The problem with global usage is poorer nations cannot afford to switch off dirty energy, and richer nations have a harsh post work hour usage. Lowering usage doesn't fix the problem that there are dozens of countries that will still continue to burn dirty till some country invests in a cleaner option.

put in perspective, even though China and the US has the most power consumption, unlike GDP, it doesn't take that many more countries after them to equate how much power they consume. So unless theres a global shutoff of power (which on its own, will have a plethora of long lasting problems if everything just shuts down), the best solution is to swap the type of energy that generates the most heat/green house gasses out.
