8. Replace old dying appliances with new (or newer) energy efficient ones.
If you really want to be green, check the Co2 cost ito manufacturing vs using the device until it is properly broken.

Point to ponder here is the sustainability of the wood source and smog if too many people decided to do it. Unless it is gas. With gas the thing to keep in mind is the cost of energy of a unit of gas vs unit of electricity. Gas where I am is more expensive then electricity, and in some cases, not as effective ito transfer of the energy than for example a stove top or the best thing ever, induction stove / plate.
