In the long run, green energy and data centers are ultimately going to be complimentary.

One of the biggest problems with investing in a renewable grid is curtailment and managing demand or production spikes. In California, they already have to turn off solar plants during peak hours to help manage overproduction.

Even if you have massive quantities of energy storage, you don't have enough "inertia" in the grid to keep power levels consistent as DC power sources flick on and off.

Data centers can act as massive variable loads that can ramp up or down that turn excess energy into something vaguely profitable. And they can also help to create demand for more supply of intermittent green energy sources.
