It’s extremely difficult and expensive to store electricity on a large scale, but that’s one of the things we’ll need to do if we’re going to rely on intermittent sources to provide a significant percentage of clean electricity in the coming years.

The rest runs off into ground or surface waters, causing pollution, or escapes into the air in the form of nitrous oxide—which, you may recall, has 265 times the…

Look for the ones that are setting themselves up to get to zero. Their emissions might not be changing much now,
