There sure are a lot of handy saving hints on this thread that I can personally attest to doing!
Where I live, we have a green bin recycle program, where you are supposed to throw out your food scraps, egg shells, pits, bones,etc. They sell these compostible bags for this purpose, but I collect my scraps in a bucket & wrap in newspaper before disposing (and I recycle my newspaper at the same time, too).
It definitely pays to switch to energy saving light bulbs. When I did this, my bill showed a significant saving. I found that if I switch off the lights when we are not in a room and unplug commonly used small appliance items when not in use, the savings adds up even further. Our bill dropped approximately $18 in a month doing this! I also try to do things in off peak electricity hours - it really does help!
