Fun fact: coal is produces more pollution of all types ranging from radioactivity to CO2 to metals to acid rain generators (SOx&#x2F;NOx) to ozone (NOx again) to black carbon aerosols (or even black carbon on snow!).  Coal extraction is bad for workers and the environment, and it&#x27;s often dangerous to mine.  It is the worst energy technology period.<p>We&#x27;re playing stage 3 of Power Grid, and coal is already getting more expensive.  Let&#x27;s just stop burning it now please.<p>Also we should leave some coal around just in case we destroy society and our descendants need to bootstrap a civilization again.  It&#x27;s hard to do that without an easily accessible fossil fuel.
