I am therefore surprised that Ike Solem (# 14), Joseph Romm (# 15) and SecularAnimist (# 18) all prosetalise about the risks we face and the benefits of wind and solar energy solutions but, nevertheless, appear to turn their faces against any major expansion in the use power from nuclear fission, apparently regardless of the type of fission.

Other fossil - fuel replacements occasionally touted in print or on the Web include nuclear fission, subcritical thorium fission, high - altitude wind power, enhanced geothermal, hot dry (or hot fractured) rock geothermal, wave power, tidal power, open - cycle ocean thermal energy conversion, and advanced biorefinery products like 2,5 - dimethylfuran, various other furans and furfurals.

Two more important solutions that would obviate the need for his list are: switching to limitless energy sources (solar, tidal, geothermal, organic fuel, wind, and even nuclear fission or fusion once we have fusion power); and reducing humanity's growth.

But with advanced nuclear power, such as LFTR or LENR or any one of 15 other safe fusion and fission schemes, we can solve it.

Mike: Nuclear fission in a power plant is a very controlled situation, unlike the natural tendency of an accumulation of a sufficient amount of the fuel.

But there are three other major energy options that need to be considered to help fill this need for non-fossil energy by 2050, one or all of which may end up being more cost effective and thus less harmful to global economic growth: nuclear fission (chapter 7), fusion (chapter 8), and solar power collected in space rather than on Earth's surface (chapter 9).
