Great piece by Brad Plumer about how climate change will put an inordinate stress on power grids, especially if they aren’t equipped to deal with it:
While scientists are still analyzing what role human-caused climate change may have played in this week’s winter storms, it is clear that global warming poses a barrage of additional threats to power systems nationwide, including fiercer heat waves and water shortages.
Measures that could help make electric grids more robust — such as fortifying power plants against extreme weather, or installing more backup power sources — could prove expensive. But as Texas shows, blackouts can be extremely costly, too. And, experts said, unless grid planners start planning for increasingly wild and unpredictable climate conditions, grid failures will happen again and again.
“It’s essentially a question of how much insurance you want to buy,” said Jesse Jenkins, an energy systems engineer at Princeton University. “What makes this problem even harder is that we’re now in a world where, especially with climate change, the past is no longer a good guide to the future. We have to get much better at preparing for the unexpected.”
As with so many issues surrounding climate change, adapting will require substantial public investment, which is much more easily said than done.
