Weatherstripping a window is a political act. Enough people join in and it becomes a social reality with real economic impact.
Monthly weatherization parties around the year and weekly energy demonstrations at the farmers' markets throughout the growing season would change the national, regional, and local situation on the ground more quickly than anything else I can think of.
Home Energy Efficiency Team has written a manual on how to throw a weatherization party.
Updated.
Pick a date for the weatherization party. Make it at least a month out. Pick a weekend afternoon (so those who go to church aren’t excluded). Schedule the event to take between four and five hours.
Find musicians or entertainers or local celebrities who will entertain the workers... tell people they can bring their musical instruments and have a jam session.
Get the word out about the upcoming barn-raising. Make an announcement at or send a flyer to nearby climate-change groups, neighborhood groups, schools and the “calendar” section of local newspapers. Give flyers to all your friends, relatives and acquaintances...
Ask people to RSVP so you get an idea of how many people will attend and how much work you might be able to complete. Generally, it’s a good idea to have 4 to 5 attendees per task and team leader. You can always have more than one team on a task if there is a lot of one kind of work to be done (say 40 windows to be weatherized).
Typical items to weatherize are:
Installing weatherization strips around doors
Put in CFL lightbulbs
Caulking exterior holes around pipes, storm windows and wires
Installing pipe insulation over hot water or heating pipes
Installing a programmable thermostat
Tightening storm windows
Insulating the band joist in the basement
Repointing the foundation
Putting a chimney flue pillow in to stop hot air escaped up the flue
Etc.
