Private investment moving to renewables, rejects nuclear

The private sector is clearly moving rapidly in the renewable direction. Clean Edge, a research and advisory group, asserts that the clean energy market grew 35 percent in 2010, and global installation of photovoltaics doubled.

The biggest positive result of the accident at Fukushima Daiichi could be renewed public support for the development of renewable energy technologies. Many influential policy makers, including President Obama, continue to insist that we must expand nuclear power to help meet our energy needs. But plenty of experts disagree…

More important is the rate of change in the cost and utilization of these technologies, particularly those that rely on wind, water or solar power and will not contribute to global warming.

The cost per kilowatt hour of generating electricity from wind and solar power has declined steadily in recent years and is projected to decline further. Energy Secretary Steven Chu predicted that they would be no more expensive than oil and gas by the end of the decade.

The cost of nuclear power, by contrast, has increased, even without factoring in the huge social costs imposed by accidents. These costs include the disruptive effects of major evacuations such as those under way in the vicinity of Fukushima Daiichi, as well as ominous — and difficult to measure — health risks.

In “Nuclear Power: Climate Fix or Folly,” Amory Lovins, a physicist with the Rocky Mountain Institute, and two colleagues argued that expanded nuclear power does not represent a cost-effective solution to global warming and that investors would shun it were it not for generous government subsidies lubricated by intensive lobbying efforts.

In The Wall Street Journal, Prof. Benjamin K. Sovacool of the National University of Singapore recently argued, in “The Business Case Against Nuclear Power,” that subsidies for nuclear power during its first 15 years of use in civilian power generation far exceeded those provided to solar power and wind power in their initial years.

Still, the big question remains. Can wind, water and solar power be scaled up in cost-effective ways to meet our energy demands, freeing us from dependence on both fossil fuels and nuclear power?

Yes, they can, say two highly respected scientists, Mark Z. Jacobson of Stanford University and Mark A. Delucchi of the University of California, Davis. In 2009 they published “A Plan to Power 100 Percent of the Planet With Renewables” in Scientific American….
