Re: [Phys-L] climate change continues apace



This is an interesting table--http://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/2/

While these things are always somewhat suspect, what I find interesting (besides how safe nuclear is even with Chernobyl and Fukushima included) is how different the numbers are for coal as used in the U.S. and the rest of the world, especially China.

Energy Source Mortality Rate (deaths/trillion kWhr)

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)
