Visit the hardware store. Buy low-flow showerheads,
faucet aerators, and compact fluorescent light bulbs, as
needed. These can be purchased from any hardware or home
improvement store. CFLs are now sold at some drug stores
and grocery stores.
If
your water heater is old enough that its insulation is
fiberglass instead of foam, it clearly will benefit from
a water heater blanket from the local hardware or home
supplies store. (To tell the difference, check at the
pilot light access (gas). For electric water heaters,
the best access is probably at the thermostat, but be
sure to turn off the power before checking.)
Rope
caulk very leaky windows.
Assess your heating and cooling systems. Determine if
replacements are justified, or whether you should
retrofit them to make them work more efficiently to
provide the same comfort (or better) for less energy.
