U.S. natural gas is being touted as a tool to weaken Russian President Vladimir Putin's influence in Europe. But how effective would an export strategy really be? In this week's show, we'll look at the reality of using American natural gas as a geopolitical tool -- and ask if cleantech could be another option.

We'll also discuss the push among Democrats to talk about climate change in the lead-up to the 2016 elections, and we'll look at the significance of recent venture activity in off-grid solar for developing countries.
