re Powerdown and food: Rockcliffe has interesting possibilities, first in having more garden space for vegetable growing, the possibility of replacing ornamental trees with fruit and nut trees, and possibly tapping more maple trees.
I've often wondered if a geothermal installation could be installed in the common corner of four back gardens, providing cheaper house warming than four separate installations would allow.
Your social media and graphic skills sound great. The first stages of transitioning involve raising awareness. At this point people are pretty much aware of climate change, dimly aware (still contesting) peak oil, but the solutions are rarely on people's horizon - home power down, moving to local resources, changing transport modes. We have power point slides if you would like audio visuals to give a talk in your neighbourhood, and are collecting various films and DVDs which we hope will soon have a library for members to borrow these films to show others.
Some of the best awareness raising starts by chatting over a garden fence, or inviting neighbours for a drink.
