Coal? Natural gas? Nuke? We can wipe them all off the drawing board by using current energy more efficiently. Are you listening, Washington?By Joseph Romm
July 28, 2008 | Suppose I paid you for every pound of pollution you generated and punished you for every pound you reduced. You would probably spend most of your time trying to figure out how to generate more pollution. And suppose that if you generated enough pollution, I had to pay you to build a new plant, no matter what the cost, and no matter how much cheaper it might be to not pollute in the first place.
Well, that's pretty much how we have run the U.S. electric grid for nearly a century. The more electricity a utility sells, the more money it makes. If it's able to boost electricity demand enough, the utility is allowed to build a new power plant with a guaranteed profit. The only way a typical utility can lose money is if demand drops. So the last thing most utilities want to do is seriously push strategies that save energy, strategies that do not pollute in the first place.
America is the Saudi Arabia of energy waste. A 2007 report from the international consulting firm McKinsey and Co. found that improving energy efficiency in buildings, appliances and factories could offset almost all of the projected demand for electricity in 2030 and largely negate the need for new coal-fired power plants. McKinsey estimates that one-third of the U.S. greenhouse gas reductions by 2030 could come from electricity efficiency and be achieved at negative marginal costs. In short, the cost of the efficient equipment would quickly pay for itself in energy savings.
While a few states have energy-efficiency strategies, none matches what California has done. In the past three decades, electricity consumption per capita grew 60 percent in the rest of the nation, while it stayed flat in high-tech, fast-growing California. If all Americans had the same per capita electricity demand as Californians currently do, we would cut electricity consumption 40 percent. If the entire nation had California's much cleaner electric grid, we would cut total U.S. global-warming pollution by more than a quarter without raising American electric bills. And if all of America adopted the same energy-efficiency policies that California is now putting in place, the country would never have to build another polluting power plant.
How did California do it? In part, a smart California Energy Commission has promoted strong building standards and the aggressive deployment of energy-efficient technologies and strategies -- and has done so with support of both Democratic and Republican leadership over three decades.
Many of the strategies are obvious: better insulation, energy-efficient lighting, heating and cooling. But some of the strategies were unexpected. The state found that the average residential air duct leaked 20 to 30 percent of the heated and cooled air it carried. It then required leakage rates below 6 percent, and every seventh new house is inspected. The state found that in outdoor lighting for parking lots and streets, about 15 percent of the light was directed up, illuminating nothing but the sky. The state required new outdoor lighting to cut that to below 6 percent. Flat roofs on commercial buildings must be white, which reflects the sunlight and keeps the buildings cooler, reducing air-conditioning energy demands. The state subsidized high-efficiency LED traffic lights for cities that lacked the money, ultimately converting the entire state.
Significantly, California adopted regulations so that utility company profits are not tied to how much electricity they sell. This is called "decoupling." It also allowed utilities to take a share of any energy savings they help consumers and businesses achieve. The bottom line is that California utilities can make money when their customers save money. That puts energy-efficiency investments on the same competitive playing field as generation from new power plants.
The cost of efficiency programs has averaged 2 to 3 cents per avoided kilowatt hour, which is about one-fifth the cost of electricity generated from new nuclear, coal and natural gas-fired plants. And, of course, energy efficiency does not require new power lines and does not generate greenhouse-gas emissions or long-lived radioactive waste. While California is far more efficient than the rest of the country, the state still thinks that with an even more aggressive effort, it can achieve as much additional electricity savings by 2020 as it has in the past three decades.

I recently testified at a Senate Environment and Public Works Committee hearing on nuclear power and spoke about how alternative technologies, particularly energy efficiency, were a much better bet for the country. Senator George Voinovich (R-Ohio) said this was "poppycock," and then asked all the pro-nuclear witnesses to address the question, "If nuclear power is so uncompetitive, why are so many utilities building reactors?"
Voinovich apparently has forgotten about the massive subsidies he himself voted to give the nuclear industry in 2005. He seems to be unaware that states like Florida allow utilities to sharply raise electric rates years in advance of a nuclear plant delivering even a single electron to customers. If you could do that same forward-pricing with energy efficiency, we would never need to build another polluting plant.
Although he is a senior member of the Senate and a powerful voice on energy and climate issues, Voinovich doesn't seem to know the first thing about the electricity business; namely, that a great many utilities have a huge profit incentive to build even the most expensive power plants, since they can pass all costs on to consumers while retaining a guaranteed profit. But they have a strong disincentive from investing in much less costly efforts to reduce electricity demand, since that would eat into their profits.
The next president must challenge the public service commission in every state to allow utilities to receive the same return on energy efficiency as they are allowed to receive on generation. That single step could lead the country the furthest in solving our ever-worsening climate and energy problems.
