Why Germany is phasing out nuclear power

Germany is involved in a wildly ambitious overhaul of its power system. Its official targets are to hit 35 percent renewable power by 2020 and 80 percent by 2050. The Green Party advocates for 100 percent by 2030.

The most controversial aspect of this power overhaul is Germany’s post-Fukushima decision to completely phase out nuclear power by 2020, which caused the heads of Very Serious People to explode on multiple continents. To many, passing ambitious low-carbon energy goals and then axing a good chunk of your low-carbon energy seems irrational and self-defeating.

There are good-faith debates to be had about the speed of the phaseout and its proximate effects. It will probably lead to a temporary increase in carbon pollution. The hope is that it will accelerate the transition to renewables.

Putting those questions aside, though, I want to focus on one of the deeper debates about Germany’s nuclear gambit. Nuclear power’s proponents frequently point out that it is one of the only low-carbon sources that can serve as “baseload” (always on) power. Baseload power is needed, they say, because renewable sources like solar are intermittent (the sun isn’t always shining) and non-dispatchable (the sun can’t be turned on and off at will). You need large, steady, predictable power plants if you’re going to have all those flighty renewables involved.

Believe it or not, Germans have heard this argument before. They just think it’s wrong. They don’t think renewables and baseload are complimentary; they think they’re incompatible.
