EASY ENOUGH TO MAKE COAL UNCOMPETITIVE:

Study: Cheaper gas lowered emissions (UPI, Feb. 27, 2012)

[T]he primary factor in the reduction in emissions from power generation was a decrease in the price of natural gas, which allowed the industry to reduce its traditional reliance on coal, they said.

The economic model used to determine this also suggests emissions could be cut further by the introduction of a carbon tax, with negligible impact on the price of electricity for consumers, the researches reported in the journal Environmental Science and Technology.

"Generating 1 kilowatt-hour of electricity from coal releases twice as much CO2 to the atmosphere as generating the same amount from natural gas, so a slight shift in the relative prices of coal and natural gas can result in a sharp drop in carbon emissions," environmental studies professor Michael B. McElroy said.
