What about a list of ideas that will save $$ and also reduce greenhouse gas emissions? The bike ones should be obvious to most of us here, but I'm listing them anyway. I would also like to know how much money and how much GHG is saved. Problem is I can't find a good calculator. Anyone know of one?
1) Ride your bike to the gym. Most folks drive to the gym, then run around a track to warm up. If you rode your bike, this you eventually might figure out that you don't need to have a gym membership. Save you $20-50 a month. Not to mention the saved gas.
2) Replace all the bulbs in your house with curly compact flourescents. This would drop your lighting costs by 70%. The bulbs are more expensive, but they last longer. The EPA says "If every household in the U.S. took this one simple action we would prevent more than 1 trillion pounds of greenhouse gas emissions."
3) Wear a sweater around the house in winter. This will cause you to turn your house thermostat to 68F or lower. Since heating consumer about 30% of the annual energy bill in northern US and Canada, this should add up fast. You should be able to save at least 10% of your bill.
4) Ride your bike to the library. If you are in the habit of buying books at Borders, the savings here is obvious. Not to mention the gas you don't burn.
5) Wash your bike clothes in cold water. Water heating accounts for 90 percent of the energy used by washing machines. Washing in hot water costs 20 to 40 cents per load.
6) After washing in cold water, hang up your bike clothes to dry. Clothes dryers eat up more energy than washers. Hang them inside in the winter if you need humidity in the air. Hang them up outside in the summer. My wife claims the clothes last longer this way.
Please add your own ideas.
