More from Al Gore: Climate bill failure costs the U.S. billions of dollars

Al Gore, who days ago called for mass demonstrations on climate change, is also arguing that the failure of Congress to pass a global warming bill is “already costing our nation billions of dollars.”

The former vice president, in a blog post on his website Wednesday, highlights a recent Reuters story about investment in green energy.

“Alternative energy investment prospects have shriveled in the United States after the U.S. Senate was unable to break a deadlock over tackling global warming, a Deutsche Bank official said,” the Aug. 11 Reuters story notes.

Kevin Parker, who heads the bank's Deutsche Asset Management Division, told Reuters that “You just throw your hands up and say ... we're going to take our money elsewhere.”

“Amid so much political uncertainty in the United States, Parker said Deutsche Bank will focus its ‘green’ investment dollars more and more on opportunities in China and Western Europe, where it sees governments providing a more positive environment,” the story notes.
