Amory B. Lovins, Cofounder and Chief Scientist, and Titiaan Palazzi, Special Aid (photos, left), of the Rocky Mountain Institute in Snowmass, CO, presented "Nuclear Power's Competitive Landscape and Climate Opportunity Cost" at "Three Mile Island 35th Anniversary Symposium: The Past, Present, and Future of Nuclear Energy" held at the Thayer School of Engineering at Dartmouth College in Hanover, NH, on 28 March 2014.
Lovins and Palazzi report that, when compared to nuclear power: (1) Efficiency and renewables are far cheaper; (2) Renewables can deliver similar or better service and reliability; (3) Renewables can scale faster; and (4) For climate protection, efficiency and renewables are far more effective solutions than new nuclear build, which indeed is counterproductive.
Lovins and Palazzi's economic critique extends not only to proposed new atomic reactors, but even to existing, age-degraded reactors. They state "Reactors are promoted as costly to build but cheap to run. Yet as Daniel Allegretti ably described, many existing, long-paid-for U.S. reactors are now starting to be shut down because just their operating cost can no longer compete with wholesale power prices, typically depressed by gas-fired plants or windpower."
Lovins and Palazzi conclude that "efficiency is clearly cheaper than average nuclear operating costs, which exceed 4¢/kWh [4 cents per kilowatt-hour] at the busbar and 8¢ delivered. Thus overall, for saving coal plants’ carbon emissions, efficiency is about 10–50x more cost-effective than new nuclear build—or about 2–12x more cost-effective than just operating the average U.S. nuclear plant."
Regarding nuclear power's retreat, Lovins and Palazzi report:
