It doesn't matter if its renewable or not if there are metric craptons of the stuff all over the planet, called COAL. Clean coal plants emit very low pollution for the amount of power they generate, and we have so much coal in the United States its not even funny so we might as well use that natural resource. I have a clean coal plant not all that far from my house, and because its a new plant with the latest technology, the SO2, NOx, and particulates are super low. The only downside is that aside from expensive carbon sequestration, even clean coal is going to produce a LOT of carbon dioxide.This is exactly the point I was trying to make. Reduce the pollution from non renewable sources, and you will also reduce CO2 output as a side effect. You don't have to believe in climate change to see this as a win win for everyone.
Now the question is, is the carbon dioxide really bad news? If we're going to see long periods of reduced solar activity, and we are in fact at a solar activity peak right now, then the answer is heck no.
So again, the real "poisons" being released into the atmosphere... no contest, there are no advocates for that. Everyone agrees those are bad. The CO2 boogieman... its up for debate. CO2 is something you breath out into your home every minute of every day.
