Why Natural Gas Is Not a Clean Energy Panacea--Alternet

Natural gas is "clean" only in contrast to coal -- just as a bacon cheeseburger can only be regarded as healthful compared with a double bacon cheeseburger.

Holding out the prospect of vast new domestic reserves, the natural gas industry is promising to make the United States an energy-rich nation once again. But we should be careful what we wish for. Spending those riches could endanger water supplies for millions of Americans while still failing to solve the climate crisis.

Electric utilities have expanded their consumption because gas-fired plants can be "turned up" to meet high peak power demand more quickly than can coal-fired plants. Natural gas is also more climate-friendly than coal and less menacing than nuclear energy.

With the discovery of drilling techniques that can extract natural gas from deep shale formations, the authoritative Potential Gas Committee estimates that the total of confirmed and potentially accessible gas reserves has grown 35 percent in just three years.

Climate bills in the House and Senate contain strong incentives to increase drilling and burning of natural gas. Seized by anti-coal fervor, most major environmental groups have gone along with the gas rush.

But natural gas is "clean" only in contrast to coal - just as a bacon cheeseburger can be regarded as healthful compared with a double bacon cheeseburger. Per kilowatt of electricity generated, gas releases 55 percent as much carbon as coal. And gas drilling poses a growing threat to our water supplies...continued.......
