The Ontario government has made a website to teach the homeowner how small changes can be done to make a big difference. Here are the links:

Hopefully if you show your family these links they will understand how easy it can be to be green. Some of the tips they give literally take seconds to do. They also include rebates on purchasing green things, such as bikes. Maybe those incentives will elicit some green behaviour.
