Mike Casey, founder and President of Tigercomm, a 100% cleantech communications firm, talks with CleanTechnica CEO Zachary Shahan about the history of the fossil fuel industry's influence on US politics, the influence it had (including on Senator Joe Manchin) on delaying and almost killing recent US climate legislation, whether or not ANY politicians fear the political power of the renewable energy industry, and how to change all of that for the better.
