Review & Outlook: The Post-Global Warming World - WSJ.com: "And so it goes with every technology that claims to promise greenhouse-gas salvation. Wind power may emit zero carbon, but windmills need up to 90% of their capacity backed up to prevent blackouts—usually with coal and gas plants. Windmills also kill a lot of birds. As for solar power, a new study from the University of Tennessee and Occupational Knowledge International finds that manufacturing the necessary lead batteries threatens to release more than 2.4 million tons of lead pollution by 2022, or one-third of today's total global lead production.
The science on climate change and man's influence on it is far from settled. The question today is whether it makes sense to combat a potential climate threat by imposing economically destructive regulations and sinking billions into failure-prone technologies that have their own environmental costs. The earnest people going to Durban next month may think so. The rest of the world is wearier and wiser."
