If the alternative is to power the datacentres with gas turbines, I would say that PV+BESS is pretty green.

The additionallity of it does point towards yes. And, while I am no fan of data centers, they still benefit the renewable energy learning curve. For those unaware, for everytime we double the number of solar panels produced in the world, the cost falls roughly 20% per watt. If Jeff Bezos bought a billion panels and threw them away, it would still result in solar panels being cheaper down the line

Oh yeah, I didn’t post this to imply it’s a good thing, just relevant to the discussion of clean energy
