Coal as a source of our electric power has <i>plummeted</i> in a decade, being taken up mostly by natural gas (but also in small part by solar&#x2F;wind). Additionally, there is no change needed for an end consumer if the power they use is switched to a different source, whereas to switch a fuel for cars means switching cars. The drive to get people on electric cars means that switching everything off of fossil fuels is a matter of switching the power plants (which we&#x27;ve seen is something that can be done quickly as with coal-&gt;natural gas).
