Looking for tips to use less gas, oil, and electricity

The director of the movie Blood and Oil was one of the speakers at our conference yesterday at IE. I am ashamed and shocked by the behavior of our government. Let's stop taking advantage of oil rich countries and just start using less! If each of us makes an effort to decrease our usage by just a bit, we can collectively lower the demand and thus lower the pressure Washington feels to FIGHT for these resources that aren't ours. So, I'm looking for tips. Let me know!
