After years of scientific research and public debate, America has reached the practical consensus that we must address climate change. Our company, Xcel Energy, agrees and so do our customers, who have joined us in promoting cleaner energy alternatives for the future.
If the debate about whether to act is over, however, the debate about what to do is just beginning. As Congress begins to create a national climate policy, I believe a few simple principles should guide its deliberations:
Any program to reduce greenhouse gas emissions must focus on the deployment of the new, cleaner technologies that are emerging today.
The nation should not abandon our domestic energy resources and become more reliant on natural gas imports and other foreign sources of energy.
No national climate change policy can be successful unless it reduces emissions at a reasonable cost.
Today in Washington, the preferred climate policy appears to be placing a cap on the nation’s carbon dioxide emissions and allowing companies to trade permits to emit at levels that decrease over time. Under a cap-and-trade system, many of the nation’s utilities would face a difficult choice: purchase expensive carbon emission credits or switch to a low-carbon fuel to generate electricity. The easy way out would mean a switch to natural gas. Natural gas emits approximately half the carbon that comes from a traditional coal plant in order to produce the same amount of electricity. Problem solved, right? Hardly.
Energy prices would rise dramatically if a significant portion of the nation’s coal-fired generating fleet were scrapped in favor of natural gas. According to a recent study by the Department of Energy, even modest carbon cap-and-trade legislation could increase a typical family’s future electricity and gas bill by $366 per year or more.
Moreover, to meet increased natural gas demand, our country would have to import significantly more gas from foreign countries, further hampering our efforts to attain energy independence. At the same time, utilities would have little incentive to develop the new, clean technologies critical for meeting the challenge of climate change.
But the true unintended consequence of a carbon cap-and-trade program would come in the form of home heating costs that would hit low-income families the hardest. These families spend a large percentage of their income on heating, and they could face dire circumstances if natural gas prices skyrocket because of a cap-and-trade program.
I believe there is a largely overlooked alternative that will reduce utility greenhouse emissions at low cost while protecting the nation’s energy security. The alternative is a Clean Energy Portfolio Standard (CEPS), similar to that proposed by Sen. Pete Domenici, R-N.M..
Similar to the successful renewable portfolio standards already found in many states, but unlike a cap-and-trade plan, the CEPS would mandate that utilities generate a portion of their electricity using renewable energy. The CEPS also would encourage them to pursue other clean energy resources, including low-emission coal technology and advanced nuclear generation. These technologies would allow utilities to reduce carbon dioxide emissions far more than renewable technologies alone. Most importantly, the CEPS would directly promote the best energy resource of all: conservation.
This flexible combination of options would spur technological development for long-term carbon emissions reduction without adversely impacting customer electricity rates. The Department of Energy predicts that a CEPS would affect electricity prices imperceptibly – only two one-hundredths of a cent per kilowatt-hour. And natural gas demand and prices would actually be lower when compared to business as usual. The need to import new natural gas supplies would be reduced, and home-heating costs would likely go down. In short, CEPS would help transform the utility industry and its technological base, reduce reliance on imported energy sources, and reduce carbon dioxide emissions at very low cost.
Our customers tell us that they are concerned about the environment and that they want to make the planet a better place for future generations. Our nation has always taken pride in its innovative spirit. We can apply the same spirit to the challenges of climate change and energy security – with the right public policy. CEPS is just such a policy, and it should be on the congressional agenda.
