It was a very bad surprise to know that professor hansen supports nuclear power plants instead of fossil fuel plants. Alternative energy means clean energy, which means eolic power, photovoltaic and other presently less popular plants. My comments:

One more risk-related point. Professor Hansen is against fossil fuels but supports the use of nuclear power. Too easy!!  I would never exchange CO2 pollution for the sneakier and deadly radioactive pollution. Maybe Professor Hansen forgets that some states are small and with a high population density. The Fukushima disaster in Japan has affected whole communities. I cringe if I think what would happen in Italy, where efficiency and controls are much more relaxed than in Japan; In Italy luckily nuclear power has been outlawed by overwhelming direct polls. Seismic, densely populated areas, pose serious safety problems to the use of nuclear power, with risks which may outweigh the risk of inundation caused by sea level rise. This issue just reinforces my belief that Professor Hansen’s opinions may carry a hefty bias. He says, let’s close up coal plants and let’s open up more nuclear power plants. Let’s swap one kind of risk for another. Now he should provide a very detailed risk analysis which considers the very high risk of exceptional events and of more frequent leaks in the atmosphere and in the water masses. The Japanese coined the word ‘Tsunami’, yet they could not guarantee the safety of the Fukushima plant, which was exposed to the recurring and historically well known phenomenon of Tsunami inundation.


From Wikipedia, ‘James Hansen’
In March 2013, James Hansen co-authored a paper in Environmental Science & Technology, entitled "Prevented mortality and greenhouse gas emissions from historical and projected nuclear power". The paper examined mortality levels per unit of electrical power produced from fossil fuels(coal and natural gas) as well as nuclear power. It estimated that 1.8 million lives were saved worldwide, between 1971 and 2009, through the use of nuclear power instead of fossil fuels. Hansen also concluded that the emission of some 64 billion tonnes of carbon dioxide equivalent were avoided by nuclear power use between 1971 and 2009. Looking to the future, between 2010 and 2050, it was estimated that nuclear could additionally avoid up to 80 to 240 billion tonnes.[93]
This paper elicited a response to criticize Hansen's analysis, from those who have historically advocated against nuclear power in general and dedicated themselves to other low carbon power technologies, including Benjamin Sovacool and Mark Z. Jacobson.[94] Hansen and his initial co-author then countered each of their attempts at rebutting his paper and rigorously displayed that all the data these scientists use to make their criticism, "lacks credibility".[95]
In 2013, with three other leading experts, Hansen was co-author of an open letter to policy makers, which stated that "continued opposition to nuclear power threatens humanity's ability to avoid dangerous climate change."[96]
