say that with my user name and business....but only for the individual....here are some ideas from my days as a solar consultant. 1) look at the electric water heater, but wait until you have produced for one year. 2) Move to induction cooking...as fast a gas, safer and electric...but you have to have the right pans 3) look at the heating units for the home...would an electric heat exchanger save you money? There are others, but those represent about 90% of the natural gas usage. Good luck. I'll probably tackle mine next year if sales are good this winter.
