If you have excess energy you cannot use at that moment, it may as well be spent removing carbon from the atmosphere. For example, if there's a giant field of wind turbines that are experiencing more wind energy than can be consumed, and there also aren't enough batteries to store it for later.
Having a more connected electrical grid so that you don't end up in this situation would probably be ideal, like what you're suggesting with using green energy to replace carbon sources.
