A related question, if I may?
Once upon a time, everyone burned coal in factories, businesses, and
homes for heating and cooking. City air quality was often atrocious.
There were even some epidemics and mass deaths as a result.
I remember my grandparents using coal, at least into the late 1950's.
But somehow, it all stopped rather suddenly. I was too young to know why
or how this was achieved.
What caused the sudden change? And, could that same effect happen again,
to bring us to a "tipping point" so encourage a rapid change from coal
and oil to cleaner technologies?
