In June 2004 the editor of an energy journal called to ask me to comment on a just-announced plan to build the world’s largest photovoltaic electric generating plant. Where would it be, I asked—Arizona? Spain? North Africa? No, it was to be spread among three locations in rural Bavaria, southeast of Nuremberg.
I said there must be some mistake. I grew up not far from that place, just across the border with the Czech Republic, and I will never forget those seemingly endless days of summer spent inside while it rained incessantly. Bavaria is like Seattle in the United States or Sichuan province in China. You don’t want to put a solar plant in Bavaria, but that is exactly where the Germans put it. The plant, with a peak output of 10 megawatts, went into operation in June 2005.
It happened for the best reason there is in politics: money. Welcome to the world of new renewable energies, where the subsidies rule—and consumers pay.

All of these complications are well known, and all of them have been too lightly dismissed by alternative energy backers and the media. Most egregious of all is the boosters’ failure to recognize the time it takes to convert to any new source of energy, no matter how compelling the arguments for it may be.
An example is the 2008 plan promoted by former vice president Al Gore, which called for replacing all fossil-fueled generation in the United States in just a decade. Another is Google’s plan, announced in 2008 and abandoned in 2011, which envisaged cutting out coal generation by 2030. Trumping them all was a 2009 article in Scientific American by Mark Jacobson, a professor of civil engineering at Stanford University, and Mark Delucchi, a researcher in transportation studies at the University of California, Davis. They proposed converting the energy economy of the entire world to renewable sources by 2030.
History and a consideration of the technical requirements show that the problem is much greater than these advocates have supposed.
