nothing not even solar power is 100% safe and i know some of the folks that used to be in the coal industry up untill recently. so i know the facts, and folks up in ohio get jobs from coal or did...
and the scrubers are now easy to mass produce, and cheep you made this poster how long ago? you will be pleased to know times have changed, and with that the effectiveness of coal baced power.
it is true that coationaly the scrubers miss a spec of sulfer or 2 but the gov regulations are the only thing that is expencive about coal, it is the safeist to produce, for wokers if nothing elce (not counting the mining prosess wich mineing is dangerous regardless of how its done or what your looking for) but the mining prosess has changed, the sludge problems gone, the loss of farmland is no longer of concern, the only hazard is the risk of collapse, and that is miner (LOL).
It is true that regardless of what is done coal will never be trully inviromentaly safe but nither is us breathing, and we do it anyway. why not give coal a chance?
