My proposal, How to Change US Energy in One Growing Season, is a finalist in the national category. You can see it at http://climatecolab.org/web/guest/plans/-/plans/contestId/5/planId/15206
You can vote for it or other proposals in the contest until November 15 at the URL's above. Please take a look.
