Speaking to the nation about the energy crisis recently, President Bush proclaimed, "if there was a magic wand to wave, I'd be waving it". Bush then proceeded to wave the perpetual "magic wand" for energy, urging more nuclear power. Candidate John McCain followed suit in his speech on global warming, linking his carbon emissions cap-and-trade proposal to massive subsidies for the nuclear power industry. The nuclear industry has launched a major effort to convince Americans nuclear power is the solution to global warming. This public relations campaign can be traced directly to a 2003 MIT study, "The Future of Nuclear Power", which recommended it. Why would public opinion matter? The MIT authors noted, "Today, nuclear power is not an economically competitive choice. Moreover, unlike other energy technologies, nuclear power requires significant government involvement because of safety, proliferation, and waste concerns." They concluded nuclear power faced "stagnation and decline", without billions in new government subsidies. The U.S. nuclear industry has in fact been in stagnation for 30 years. The last nuclear plant built in the United States was ordered in 1978. The industry blames environmentalists for its collapse, yet government policies have always favored nuclear power. Nuclear power lost its market primarily to coal-fired power plants decades ago. However, coal is one of the largest carbon dioxide emitters, and now recent actions by state regulators, environmentalists and Wall Street have resulted in a virtual moratorium on new U.S. coal-fired power plants. The nuclear industry seeks to exploit this, by promoting the message that nuclear power is our only choice left -- regardless of cost.
Some U.S. utilities are now proposing a new wave of nuclear plants. However, recent cost estimates are causing "sticker shock" -- at least $9-$12 billion per plant, roughly double the $5 billion per plant estimated just last year. Few private projects in the history of the world have been so costly.
Making a leap from economical coal-fired plants, straight into buying a nuclear power plant is akin to shopping for a Rolls Royce, because your good old Chevy died. Sure, the Rolls Royce will get you around -- but can you afford the payments? Will utility customers be happy to pay so much more for electricity?At $9 billion for an 1100 megawatt nuclear plant, nuclear generating capacity is more than 12 times the price of the same power capacity in gas turbines, and 2 to 3 times more costly than comparable power output from wind farms. In addition to costing far more, the nuclear plants would not come on line for at least 10 years, delaying reductions in greenhouse gases by at least a decade.
Faced with such bad numbers, the nuclear industry has admitted it cannot find backing from Wall Street. Instead, the industry is turning to taxpayers. Congress has authorized $18.5 billion in Federally guaranteed loans for new nuclear plants. This will only be enough to fund two plants, so the industry is pushing for hundreds of billions more. The Congressional Budget Office has estimated the risk of default on these nuclear loans to be at least 50 percent. This massive new outlay for nuclear power would eclipse all public funds for all other energy sources combined.
The nation is now reeling from the aftermath of people buying homes they could not afford, because someone was reckless enough to loan them the money. Do we want our utilities to buy power plants they can't afford?The taxpayer funded banquet for the nuclear industry would not end with power plants. This initial pork would be followed by taxpayer subsidies for fuel enrichment, plant decommissioning costs, and perpetual taxpayer funds for thousands of years to maintain the nuclear waste.
There is another way. Most utilities across the country have adopted a strategy of prudence, recognizing we are finding our way to a renewable energy economy. These utilities are using gas turbines as an inexpensive way to add generating capacity needed to assure reliability of power supply. They then minimize actual fuel consumption, by purchasing wind and solar power and funding improved efficiency. Midwestern utility Xcel Energy, a leader in this approach, plans to reduce greenhouse gas emissions by 20% by 2020, while increasing output and keeping rates affordable.
Large solar electric farms are now being installed in the desert Southwest, and wind farms chiefly on the Great Plains. This is already making a big impact. Latest figures from the American Wind Energy Association show new wind farms made up about 30% of new U.S. generating capacity in 2007. Wind energy is now cost competitive even with coal. The U.S. Department of Energy recently announced wind energy can provide 20% of our electricity by 2030, equal to nuclear energy's current proportion.The sun does not shine nor the wind blow all the time, so peak solar and wind power can be stored using simple compressed air technology, to provide a steady source of power. Mason, Fthenakis, and Zweibel (Scientific American, Jan. 08) show by 2050 these technologies, together with sporty new plug-in hybrid automobiles, can completely eliminate our need for imported oil, with renewables producing 69% of U.S. electricity. Additional technologies to provide even more clean energy include plasma generation plants that cleanly burn municipal waste, cellulosic or algal biofuels, geothermal, and ocean source generation. With no federal loan guarantees, billions in venture capital is flooding into renewable energy, a new growth industry.
We need not accept the message of fear that nuclear power is our only choice left. There are a lot of ways to generate a kilowatt-hour.

Indeed, not the only way
At $9 billion for an 1100 megawatt nuclear plant, nuclear energy allows $0.8 billion per year in savings through the use of uranium fuel instead of natural gas. Severance speaks of natural gas combustion turbines as "an inexpensive way to add generating capacity". Don't be deceived: this is not at all the same thing as a way of adding inexpensive capacity. Some of that $0.8 billion is government royalties. The CBO's estimate that loans to nuclear developers have a 50 percent chance of default is wishful thinking. If government did not guarantee the loans, it would be able to profit by interfering with the nuclear developments, and given that incentive, it might be able to scuttle half of them. But if its ill-gotten natural gas revenues are taken from it by the creditors of the sabotaged nuclear projects because it guaranteed those loans, it has no reason not to do the right thing: let the nukes start. It isn't nukes, after all, that have had fatal accidents in recent years. That would be wind power, at such a rate that if it were scaled up to equal nuclear energy in the USA, it would kill around 500 a year. And natural gas has, of course, frequent fatal explosions. by GRLCowan (0 articles, 0 quicklinks, 0 diaries, 10 comments) on Friday, Jun 13, 2008 at 10:56:44 AM

Reply: Gas turbines as bridge strategy
Most of this commenter's remarks make no sense, so do not need a reply. However, the commenter did raise a valid concern about utilities continuing to use gas turbines -- i.e. the cost and availability of natural gas. The commenter quoted the first part of the clip that utilities can build economical gas turbines to have enough power generating capacity to assure reliability of power supply. However he failed to mention what I said is the last part of that strategy, which is to purchase wind and solar power, and fund conservation efforts, to minimize the actual fuel consumption by these gas turbines. Note that with these strategies, Xcel Energy is actually projecting a 20% reduction in its total carbon emissions by 2020. We are not necessarily talking about any net increases in overall natural gas usage. Natural gas is an essential "bridge" fuel to a renewable economy. As the authors of the Scientific American study note, it will continue to play this role for decades to come, but primarily as an economical means to assure grid reliability, not as a primary fuel source. As renewable energy sources grow, it will be gradually phased out. As noted a key part of this utility stategy is to fund conservation programs, including programs specifically designed to cut existing natural gas use such as heating our homes. Also, solar power is an excellent peak-following power source, so bringing in more solar power will automatically cut existing utility uses of natural gas for peak power turbines. I do not argue we have unlimited natural gas supplies. However a prudent course of action can conserve this resource while continuing to use its flexibility as a cost-effective bridge to a renewable economy. by Craig Severance (1 articles, 0 quicklinks, 0 diaries, 1 comments) on Friday, Jun 13, 2008 at 2:04:06 PM
