This week, the Obama administration finally completed its landmark climate rule that will require states to cut power plant carbon emissions. It's been hailed by supporters as historic, and demonized by opponents as an economic threat.

But is it really all that big of a deal? That depends on how you look at it.

In this week's show, we'll talk with Michael Grunwald, a senior reporter at Politico, who argues that the climate law is not very ambitious when it comes to carbon reductions. However, it will still be good for clean energy businesses, which will see new state markets open up because of the rule. We'll examine all the implications.

Later in the program, we'll look at why the U.K.'s Green Deal efficiency program failed, and ask if there are lessons for U.S. efficiency programs. In our last segment, we'll discuss the philosophy behind Bill Gates' billion-dollar investment in clean energy.
