During that drop in generation, did wind and solar plants go offline first? Whether or not solar and wind contributed to the blackout as a root cause, we do know that wind and solar don’t contribute to grid stability in the same way that some other power sources do, says Seaver Wang, climate lead of the Breakthrough Institute, an environmental research organization. Regardless of whether renewables are to blame, more capability to stabilize the grid would only help, he adds. Reversing a plan to shut down Spain’s nuclear reactors beginning in 2027 would be helpful, Wang says.
