A 'Credible' Afghanistan?; The Cost of Renewable Energy

Hosted by

Hamid Karzai has been declared re-elected as President of Afghanistan. Now that Abdullah Abdullah has dropped out, there won't be a run-off. The UN Secretary General is among those telling Karzai to find another way to demonstrate "credibility" to his own people and the rest of the world. What will this mean for sending more American troops? Also, billions of federal dollars are going to "clean energy" projects.  Are they as "clean" as they're made out to be? How much will the "hidden costs" of renewable fuels counteract their benefit to the environment?
