Loud voices in the climate community ignore the actual science and constantly use cherry-picking, strawmann arguments and ad hominems to try and deny the undeniable.
Pretending that we have been exaggerating, while it's likely even worse than we feared (again, based on data).

So good to see the green spaces full of life - cyclists, walkers, even kayakers! 🚴♀️🛶

As coal power plants go offline, data centers boot up, and more people switch to electric appliances and vehicles, the region's electrical grid is strained and there’s not enough renewable energy projected to come online to fill the gap.
As NW faces rolling blackouts, study says renewable energy may not be enough
The greater Northwest region could experience a 9-gigawatt energy gap by 2030, or about the same amount of power consumed by Oregon. That could lead to rolling blackouts during extreme weather events starting next year, a study suggests.
