Although it may not seem so at first glance, coal plants can have a lot to do with driving green, or at least they do for some drivers (to help make ethanol, for example) and may a lot more in the future if EVs become more popular. With that in mind, we take a quick detour over to our friend Mike over at Treehugger, who sent us a link to his post on the perils of "carbon sequestration", which is basically turning a coal plant's CO2 emissions into liquid form and burying them deep in the ground. While the benefit is that you limit the emissions before they get into the air, Mike points out research that shows this is simply not feasible for the industry as a whole (in Australia alone, for example, to sequester all of the country's coal plant emissions would mean injecting 50 cubic kilometers of liquid CO2 into the ground every day). Of course, all that CO2 is currently going somewhere, and we need to figure out ways to reduce it, but burying our head CO2 in the sand doesn't seem to be the answer.
