Patenting seems smart, but if the Green idea relies on government funding or mandates (laws) in any way to achieve profitability or sustainability you should be careful. As soon as the other side of the political spectrum takes over, the Green stuff might get unwound. It is a political target for both sides, meaning a lot of unpredictable risk. One side is pushing it on people who do not want it and the other side doesn’t want that. There will still be a target market for certain Green things no matter who is in control though, because there is an identifiable subset of consumers who value it enough to pay for it.
