I've cut down driving a lot. I drive approximately 10 minutes Mon, Wed, and Friday. I take one other 40 minute total trip once per week.
I'm grocery shopping every two weeks.
I could cut out my Mon,Wed, Frid driving if my younger boys would just learn to ride a bike.
The boys also all need new bikes. *sigh*. I only have one that would fit any of them right now.
We installed a programmable thermostat, and are replacing nearly all of our single-paned windows asap. We've been doing them one or two at a time, but we have decided just to lay out the cash now and be done. We are also replacing our front door which is old and leaky.
