Goodbye Hoover Dam?
SEARCH BLOG: GLOBAL WARMING
No, Hoover Dam has not sprung a major leak. Neither have the Tennessee Valley Authority dams. And China's Three Gorges Dam which is due to start generating hydroelectric power in 2008 has not run out of water. These hydroelectric dams are damning us all... according to an article in Scitizen.
What had sparked the reaction was my calculation that Brazil’s Balbina Dam was worse than fossil fuels in terms of greenhouse-gas emissions (Fearnside, 1995). A Canadian group had also shown that northern reservoirs can release greenhouse gases (Rudd et al., 1993). This was only the beginning of the long debate that continues to this day. Large emissions from water passing through the turbines of tropical dams have been have confirmed by direct measurements of methane release immediately below the Petit-Saut Dam in French Guiana (April et al., 2005) and the Balbina Dam in Brazil (Kemenes et al., 2006). Dr Philip M. FearnsideAre you beginning to get the sense that no option for human civilization is either politically-correct or global warming-correct? Well, actually, this tells me that the U.S. should earn CO2 credits by shutting down hydroelectric plants and building old-technology coal-powered plants.
Are you beginning to get the sense that none of this is making a whole lot of practical sense?
The other day, I pointed out that a rather mundane elimination of traffic signal inefficiency would have real benefits for both the environment (not just CO2 reduction, but a host of toxic gases) and all of us individually by reducing our driving cost and time.
What I don't see from those who are demanding reductions in CO2 or other "greenhouse gases" are practical approaches. Rather it's all about creating penalties. Raise taxes. Create fees. Force uneconomical changes in the name of "risk management."
Okay, who is going to tell the Chinese that they can't start operating their new hydroelectric dam that was "clean" until this study said it wasn't?
(sssshhh... nuclear power the French were right)
