Kipp,
Hats off to you for your energy moves. I have gradiose ideas in the future, but for now we unplugged our extra refridgerator/freezer and consolidated last month. Saved a couple of kw-hr/day. We have also changed our driving habits a bit.
My longer term goals are to invest in a grid-tied PV solar array on our home to supply ~50% of our electricity and purchase a hybrid vehicle in a couple of years. If VM continue for another year or so I may be able to pursue this vision sooner rather than later. Unfortunately, PV is not a good return on investment at current costs and energy prices, but in the long run I know it is the right thing to do.
How well does the on-demand water heating work? Do you have one for each faucet? Is it immediately hot?
