The thing is that in the Victorian Edwardian era coal was indeed very dirty and homes belched out filthy smoke that cost lives. Then in 1952 along came the clean air act and this made life cleaner and safer for city dwellers. In line with the Clean air Act the coal power stations were upgraded so that their emissions were mainly steam and no dirty particulates or black smoke was allowed to be emitted. This safeguarded the health of citizens. Therefore modern coal power stations are not dangerous to health although burning coal in your fireplace still is dangerous since  domestic chimneys do not have scrubbers.

Therefore campaigns against coal power stations are misguided and may lead to worse air pollution as homeowners burn coal and wood in their fireplaces to keep warm.
