Nuclear power, not renewable energy, is risky course for U.S.

Given the seriousness of the climate crisis, many thoughtful people, including Deseret Morning News Editor Joe Cannon, have argued that coal cannot be the source of our energy growth. I agree. He also advocated the revival of nuclear power as the mainstay of electricity growth amounting to 300 large power plants. This is risky, costly and unnecessary. Contrary to widely held opinion, renewable energy sources are quite sufficient to provide ample and reliable electricity for the United States.

For instance, the wind energy potential of Midwestern and Rocky Mountain states is 2 1/2 times the entire electricity production of the United States. Utah's neighbor, Wyoming, has almost as much wind energy potential as all 104 U.S. nuclear power plants combined. Solar energy is even more plentiful. The sunshine falling on rooftops and parking lots alone can provide much or most of the electricity requirements of the United States. Utah also has geothermal resources it can tap.

Wind energy is already competitive with or more economical than nuclear energy — about 8 cents per kilowatt hour in very good areas. A recent independent assessment by the Keystone Center, which included industry representatives, estimated nuclear costs at 8 to 11 cents. Intermittency is not a significant issue until very high levels of penetration. For instance, a 2006 study prepared for the Minnesota Public Utilities Commission found that an increase of just over 2 percent in operating reserves would be sufficient to underpin a 25 percent renewable energy standard supplied by wind.

Solar energy is somewhat more expensive today but costs are coming down rapidly. In December 2007, Nanosolar, a Silicon Valley company, produced the first solar panels costing less than a dollar a watt. When installed in megawatt chunks on commercial rooftops and commercial parking lots, the solar electricity is generated at the point of demand, avoiding the need for investments for major transmission lines, which can run into hundreds of millions or even billions of dollars. At an installed cost of $2 per watt, expected in the next few years, delivered parking lot solar energy cost will be 14 to 15 cents per kilowatt-hour. This is comparable to new nuclear plants at a delivered cost 13 to 16 cents. Indeed, recent trends in solar costs indicate that nuclear power may become economically obsolete by the time the proposed nuclear power plants would come on line.

Utah's existing hydropower and natural gas resources can be integrated with wind, solar energy and an efficient smart grid to provide reliable electricity. With the maturing of energy storage technologies, even coal-fired power plants can be phased out over a period of 30 to 40 years.
