Unsettlingly, usually, these discussions involve more strong opinions than data. Some people believe that one of these alternative (they are not all sustainable) energy options is the silver bullet that will solve both the climate and the energy crisis. Other argue that there is no silver bullet and that what is required are a variety of silver BB’s: a mixture of technologies, along with greater energy efficiency and preservation of habitat (forests). Do we really just need to build huge number of nuclear plants or wind farms to solve the problem? If, instead, we are going to use a mix of alternative energy sources, which ones should we use and in what quantities?

The IAEA has revised upwards its nuclear power generation projections to 2030, while at the same time it reported that nuclear´s share of global electricity generation dropped another percentage point in 2007 to 14%. This compares to the nearly steady share of 16% to 17% that nuclear power maintained for almost two decades, from 1986 through 2005.
