My heating bill is too high.  How can I lower it?  Give me three suggestions.

(1) You can insulate your house better.  This can often be done cheaply, such as by covering your windows with plastic during the winter.  You can also invest in permanent insulation such as double-paned windows and new attic insulation.
(2) You can wear warmer clothing and turn down the heat.  It's not too bad to bundle up during the winter!
(3) You can invest in a heat pump.  Heat pumps are more energy-efficient than traditional heaters.
