I have also been working on changing out our incandescent light bulbs for CFLs. Generally, the only bulbs we haven't changed out are the dimmable lights - chandeliers and flood lights for the most part. I still haven't changed all of the guest room lights but those rooms are rarely used so the impact would be minimal compared to the cost to change them out. I also need to change out the bulbs in a few overhead fixtures upstairs - maybe this afternoon! I generally use the Sylvania bulbs that I buy at BJs Warehouse. The Sylvania CFL instant-on bulbs are really great for bathrooms or anywhere you need immediate bright light. They cost about $10 for four 60 watt equivalent bulbs, compared to $11 for eight of the regular CFLs.
3) Compost. We started composting earlier this year which we hope will have the dual benefit of helping reduce waste that goes to a trash incinerator while also providing some great mulch for our plants. (Read about our composting efforts here and here.)
4) Appliances. Our most recent appliance purchases have been Energy Star Certified or more environmentally friendly. We bought our new washer and dryer earlier this year to replace our energy-hogging 8 year old models. During our whole house renovation we bought an Energy Star rated refrigerator and Bosch dishwasher. We also installed a second tank-less hot water heater, and a second high-efficiency furnace.
5) Insulation. When we redid the house we added foam insulation in the attic and a lot of insulation in the walls in the basement, first and second stories. I think this has made a huge difference in our energy consumption. In fact, our gas and electric bills are only a few dollars more per month than they were before our renovation - and that includes the extra 1800 square feet!
6) Reduce waste. Overall, we try to reduce the amount of waste we create. We use our fridge filter instead of bottled water whenever possible. I use a permanent coffee filter. We rarely use paper cups and plates except for very large parties. We don't use paper towels in the bathrooms. We still use paper napkins and paper towels, but hopefully when the kids are a little older (and maybe less messy?), we'll be able to reduce our paper napkin use. We sell, give away, or donate things that we are no longer using instead of putting them out with the trash.
