Things you can do that save you money while also reducing pollution and other planet harming activities:
Indoors, in the winter when you are heating the house, wear a sweater and other warm clothing, and turn the thermostat a few degrees cooler. You will save money on your heating costs. You will still be comfortable. You just have to wear more clothes in your house. That's not much of a sacrifice, is it? And a dollar saved is a dollar earned*. Another advantage, not often thought about, is that when you go outside there is less of a sudden change, so you may be less likely to catch cold or other illness.
Use less gasoline. You can do that by putting on fewer miles each year. Don't make unecessary trips, combine errands, choose closer destinations when there is a choice, etc. When it comes time to get a different car, get a smaller one, or a more fuel efficient one. When it comes time to move, move closer to where you work. Or maybe you can get a job nearer to where you live.
I asked for suggestions on this topic on our Earthchurch discussion list, and I got dozens! There are too many to list here, but here's a selection:
Take the bus instead of driving. (also, walk or bike)
If you drive, set up a rideshare system so several people can leave their cars at home.
Have an automatic thermostat that lowers temperature at night and raises it during the time you are at home.
Get up earlier and go to bed earlier, to save using electricity for light;
also get fluorescent bulbs.
Use solar barbecue instead of coal, gas, or electric.
Take shorter showers to use less hot water hence less energy cost.
Wash your clothes with cold water, using a cold-water detergent.
have fewer or no children
live in an apartment
buy services instead of things
repair things instead of trashing them
Get some canvas grocery bags and take them with you to the grocery store.
tell others about the things on this list
*A dollar saved is worth quite a bit more than a dollar earned, because it's tax free!
