Here at PPI, we’ve long argued that for the U.S. to meet its carbon reduction targets, we need to assume a “Leave No Fuel Behind” outlook. Currently, coal — the most polluting and the cheapest of sources — accounts for half of all power produced in the U.S. There’s no doubt that we need to scale back our use of coal. But replacing that base-load capacity will be a tall order.
Ramping up renewable sources like wind and solar should, of course, be a priority, but they simply won’t be reliable energy sources for decades to come. We’ve also argued for an expansion of nuclear power and more research into carbon capture and storage, and we applaud the administration’s recent efforts to jumpstart our nuclear industry. But let’s not forget the quickest interim source we can use to begin cutting back on coal emissions: natural gas.
In a column last Friday, the Washington Post‘s Steven Pearlstein makes a compelling case for scaling up natural gas:
The silver bullet: Decommission about two-thirds of the electric-generating capacity fueled by cheap and plentiful coal, and replace it with power generated from cheap and plentiful natural gas, which emits half as much carbon for each megawatt of electricity.
Pearlstein points out that a confluence of events — the overbuilding of gas-fired plants in the ’90s and an increase in supply thanks to new drilling techniques — has made natural gas a feasible substitute for base-load electricity generation. A Congressional Research Service study found that if our currently underutilized gas plants were to double their production, about a third of coal-fired power would be displaced — a major step toward meeting our emissions reduction targets.
In trying to wean ourselves off coal, the most effective method would still be to put a price on carbon. This week, the Senate is back from recess and will make a “last-ditch attempt” to put together a compromise cap-and-trade bill. But as legislators try to break the gridlock over cap-and-trade, they should keep their eye on alternatives that can begin to ease the grip of coal on our economy. Nudging utilities toward natural gas seems like a good start.
