Venture Capitalists are really excited about the energy technologies and are putting more and more money into three main areas: renewables, energy efficiency and transportation.
Trae Vassallo made a comment that struck me: Energy industry has been around a long time with little innovation." There has been a lot of movement from the Goldman Sachs of the world and others, and investors are excited about that.
From a communications point of view, I think there's also a lot of excitement about energy solutions because of the breadth of issues the topic touches: energy independence, global warming national security, clean air, healthy people, etc. People can wrap their minds around it, understand how it touches so many facets of our lives and the wealth of solutions.
