The odds matter because nuclear plants provide so-called “baseload” power, which is to say that they produce electricity 24/7 — when they’re on. Geothermal power— tapping energy from underground sources of heat — also has the virtue of being baseload. While geothermal plants can lose potency during the hottest part of the day, they don’t stop producing completely. Solar and wind are considered “intermittent” sources as they’re at the mercy of the sun shining and wind blowing.
