Make a couple of your new year's resolutions green ones! Here are just a few easy suggestions:
Actually use those reusable bags that have been hanging in your closet for the past year. I have 1 Bag at a Time bags, which are great and I highly recommend. If you have none, spring a few bucks - you can find them practically anywhere these days.
Turn your heat down a few degrees when you leave for work during the day. Ask yourself the age-old question: if the heat is down during the day when no one is home to feel it, is the house actually cold?
Replace regular light bulbs with CFLs. Yes, they are pricy, so look for sales (at Target, Home Depot, Lowes, etc.) and buy just a couple at a time to reduce the financial strain. If you are somewhat crafty, get some glass paint and create holiday ornaments out of the old bulbs.
Start thinking of a green project to take on when the weather turns: build a compost bin, plant a vegetable garden, plant a tree. Be creative!
