Bill Chameides is the Dean of Duke University Nicholas School of the Environment and he says:
"Coal is the dirtiest fossil fuel we’ve got. BTU to BTU, we get more pollution from coal than from petroleum and way more than from natural gas.
Most of the pollution goes up in smoke, so to speak. It’s emitted as
gas (carbon dioxide, mercury, sulfur dioxide and nitrogen oxides) or as
fine particles that find their way up through the smokestack and into
Chameides has previously written about the impacts from gas development. And he is not, nor am I, suggesting that gas production has no impacts. It does and must be strongly regulated to reduce its impacts on air, land, and water.
Yet, Chameides knows that the comparative impacts of coal, oil, and gas on land, air, and water are not equal. Those seeking truth cannot ignore these energy facts.
