3. Clean coal has more to do with the technologies to combust it and turn it into usable power. The emissions are significantly less than traditional coal burning facilities.
4. clean coal isn't a thing that is mined. There are significant untapped coal resources in the continental United States, technology has evolved the cleans the way it is burned and significantly reduces carbon emissions, but even that isn't good enough for environmentalists.
5. Nuclear is the most efficient, but it is fought at every turn due to concerns about accidents, misinformation about the process and environmental whackos.
I work in some of the green energy areas. There is a lot of good, but the expense and efficiency of wind and solar in particular leave a lot to be desired at this time.
Thanks, Dude. With utmost sincerity, I had absolutely no idea how coal was mined and why. It makes sense that there are "veins" of coal but does it cause too much environmental damage to just dig up the entire area instead of mining it?
I've seen a few news broadcasts in my life about coal mining accidents and I have no idea how guys can mine coal. I'd be so freaking claustrophobic I probably wouldn't be able walk more than five feet in.
