The following link is from the LA Times, but at first blush it looks like something from the Onion.

This just goes to show how out of touch people are with the utility system that is the lifeblood of our society.  Does anyone think that a few hours of a fossil fuel plant’s operation will have a significant effect on the climate?  The California wild fires last year released multiple years worth of state GHG emissions.  Worldwide GHG emissions increased by 2.5 billion metric tons over the past couple of years, 40% of that from increased coal generation in China, India, Africa, and some third world countries.  Those things amount to GHG Emissions orders of magnitude larger  than the emissions of a few generating plants for a few hours per day.

What the blackouts will cause is death, especially in older and poorer areas,  and major financial damage as businesses leave the state for somewhere where they can operate without fear of having their processes shut down at undetermined times which can severely damage equipment and material in process.
