USA, California:

Nuclear Woes Could Create a Window for Geothermal Energy (KQED)

One of California’s two nuclear power plants remains offline amid roiling speculation about its future. At a geothermal energy conference in Sacramento this week, the head of California’s Independent Energy Producers association put the odds of the San Onofre Nuclear Generating Station (SONGS) “ever” coming back online at 50/50. 

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.
