Drive at 55 mph. Significant fuel savings compared to 65 or even 60.
Consolidate or eliminate extra trips for shopping. Make a note of the stores you see on the way home from work. Stick a few pieces of scrap paper on the fridge with a magnet. When you see something is running out, write it on the page. Take that page to work with you every day. On the way home, stop & get whatever-it-is. If your kids come home from school and put more stuff on the next piece of scrap paper on the fridge, take that list with you the next day.
Teach your kids that there is no more "instant gratification," but instead, whatever they want that isn't in the house at the moment, will have to be posted on the fridge and wait for the next scheduled shopping run.
Buy milk and other core essentials ahead of need, i.e. always have enough to last you in case you have to postpone a regular shopping day for whatever reason.
If weekend shopping trips are needed, talk to the neighbors about car-pooling those. Everyone get everyone else's phone number in the neighborhood, and organize so all plans are made a day ahead.
If everyone in the neighborhood has a computer at home (reasonable assumption), set up a Yahoo Group (groups.yahoo.com) for your street. Set up the access for "members only, approved by moderator," to prevent crafty burglars getting in and collecting information; anyone who wants to join has to send you their phone number so you can call 'em and verify their address is in the neighborhood.
Then everyone post their various transport-related needs, e.g. "Ms. Smith here, my kids want to go to the movies on Saturday afternoon," and see how many of those trips can be carpooled. "Ms. Alvarez here, my kids want to go to the movies too, let's go together," and "Laundromat on Friday night, anyone else?" "Yeah me too, call before you leave and I'll be waiting on the sidewalk."
This can also naturally turn into a carpool-commuting network, for sharing rides to a downtown area or to a local public transport system.
If you need telecommuter systems in the San Francisco Bay Area, private-message me or go to
www.cooperative-digital.com which is my company's website (I haven't posted our URL before because I don't believe in using these forums for free advertising, but it seems appropriate to mention here because telecommuting is becoming a critical need right now). Our web page has a section on telecommuting benefits, that is written with the business owner's perspective in mind. I can make a pretty convincing case to almost anyone that telecommuting will benefit their company.
If you can't telecommute and the public transport in your area isn't adequate, see about getting time-shifted work hours, so you aren't driving in heavy traffic. Stop-and-go is enormously wasteful, any steady speed is far better. You could try starting an hour earlier and leaving an hour earlier, or starting an hour later and leaving an hour later.
Think ahead to the winter heating season:
All the prices will be up unless you heat with solar or with electricity that comes from a hydroelectric, nuclear, or wind site. Now's the time to buy heavy curtains to hang over all of your windows. In a pinch, cheap blankets or almost any other heavy cloth will do. It may not be aesthetic, but neither is an empty bank account after you've paid the heating bill. Open the curtains during the day to let the sunlight warm up the rooms, and close them as sunset approaches.
Buy lots of long underwear, right now, before the seasonal price increase occurs. During the cold months, wear long underwear (top as well as bottom) indoors at home all the time; it's worth the equivalent of a five-degree increase in indoor heat.
Weatherstrip window and door frames. Minimize use of the clothes dryer (buy a drying rack or set up indoor clothes lines). If you can selectively turn off heat in certain rooms, do it: close off the vents, turn off the radiators, or whatever, and keep the doors to those rooms closed.
Turn the thermostat down to 50 degrees when everyone is out or sleeping. You can do this manually before you leave for work and before you go to bed at night. If you want to wake up to a warm house in the morning, get a thermostat with a timer (about $30 - $50, will pay for itself quickly) and set it for your regular weekday schedule. On weekends you can bypass it for heat during the day.
All of this stuff is common sense and we should be doing it anyway, but a sudden price increase is a good nudge to get going on it right now.
