Carbon sources of energy in the nuclear power lifecycle is an argument for more nuclear to me.Joffanhttps://www.blogger.com/profile/18025437863119781181noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-84653086063428727832008-01-16T19:07:00.000-06:002008-01-16T19:07:00.000-06:00Joggan, Mining does use diesel fuel, and other fos...Joggan, Mining does use diesel fuel, and other fossil fuels. Hence it generates some CO2. Milling also does fossil fuels. Uranium enrichment via gaseous diffusion draws a lot of coal fired electricity. <BR/><BR/>You are right though, Wind and Solar do require more building and structural materials. At the moment these are in short supply and growing more expensive. But if the Chinese stop building their economy, who knows.Charles Bartonhttps://www.blogger.com/profile/01125297013064527425noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-51436264938797350702008-01-16T18:47:00.000-06:002008-01-16T18:47:00.000-06:00I seem to recall that wind uses significantly more...I seem to recall that wind uses significantly more concrete and steel than nuclear too. I am a little surprised that solar PV calculates out as high as that.<BR/><BR/>A small note, though - mines don't generated CO2 intrinsically, they just use energy (which <I>currently</I> is supplied by fossil fuels). Uranium enrichment is already undertaken without CO2 generation in France. Making concrete on the other hand has intrinsic CO2 generation as well as energy use.Joffanhttps://www.blogger.com/profile/18025437863119781181noreply@blogger.com
