Deaths by energy source

Forbes has an interesting article looking at the health effects of different energy sources, more specifically, the number of (human) deaths per unit of energy produced.  For all the publicity nuclear energy accidents get, it’s worth noting that the mortality rate from nuclear energy is about 90 deaths per tkWhr (trillion kilowatt hour of energy produced), while coal is 170,000 deaths per tkWhr!  To be fair, that coal rate is the global average and the US is much better than that (mainly because of existing pollution controls)…but even then, it’s a whopping 15,000 deaths per tkWhr.  The complete list:

Energy Source               Mortality Rate (deaths/trillionkWhr)

Coal – global average         170,000    (50% global electricity)

Coal – China                         280,000   (75% China’s electricity)

Coal – U.S.                               15,000    (44% U.S. electricity)

Oil                                               36,000    (36% of energy, 8% of electricity)

Natural Gas                                4,000    (20% global electricity)

Biofuel/Biomass                    24,000    (21% global energy)

Solar (rooftop)                              440    (< 1% global electricity)

Wind                                                 150    (~ 1% global electricity)

Hydro – global average          1,400    (15% global electricity)

Nuclear – global average            90    (17%  global electricity w/Chern&Fukush)
