Here's some ideas:
Vow to recycle more (This is how long it takes for some of our garbage to break down)
plastic ...over 500 years

organic materials....6 months

Unplug your electronics when they are not in use. Make sure the dishwasher and washing machines are full when you run them.
Switch to compact fluorescent bulbs They’ll save you money in the long run, and the quality of light they emit has greatly improved in the last few years.
Install a digital thermostat Then you can set it so its not running when no one is home and have it cool down or heat up some just before you are due to arrive
Think back to what your driving habits were like when gas was $4/gallon. Have you slipped back into your old habits?
