Some of us are working full-time on renewable energy projects - my company is one of them. The US may not have a policy in place, but the Senators we have met with are supportive of our efforts, showing us where more general business policies can be helpful to our business.

FYI, the problem with developing renewable energy is not the actual energy production itself. Every inventor out there has a "better" turbine to try, The barriers lie in regulatory limitations and the massive amount of capital needed to build out projects.
