Originally posted by normhead This area at one time was completely falling apart because of the pollution from acid rain, mostly caused by coal fired plants... so it begs the question... is the coal technology of today better than that killed so many of our lakes and many of our maple sugar bushes? The lakes are coming back, the sugar bushes will take a lot longer.. but I have no idea if it's more environmentally designed coal plants.. or that coal plants have been shut down. For years here, coal fired plants in the northern US were killing fish in lakes that had no other sources of pollution... I have no desire to go back to that. But who knows, maybe the new plants have scrubbers etc...
Norm, the EPA successfully reduced emissions by banning medical and municipal incinerators, which until 1990 rivaled power plants for mercury pollution. That doesn't answer the question though, as coal plants still continue to be the main culprit of acid rain and sulfur dioxide. Older plants have now been shut down and new scrubbers, ponds and activated carbon when burning coal has improved harmful emissions. Most of the coal plants are base load plants, or only put in operation when system demand is being reached. As said in another post, China is purchasing a lot of US coal and a terminal for exporting more coal is being built on the West coast, this is good our declining economy creating thousands of jobs in Wyoming and Montana and other states. I guess the answer depends upon what side of the fence a person is on, but if coal plants are suddenly taken off line, major blackouts will occur often. I did read where more natural gas burning plants are being built to provide us with power, but government groups also want to do away with hydraulic fracturing and other ways to extract gas. Our countries runs on hydrocarbons and until another source comes to be or more nuclear plants are allowed I think improving the plants we have is the only answer. The Keystone Pipeline was a perfect match for Canada and the US, but that plan was cancelled due to our current administration policies.
