The best way to improve your home's energy efficiency is to make sure all of your windows and doors are properly sealed. You can also install insulation in walls, ceilings, floors, and attics; use LED or CFL light bulbs; replace any old appliances with more energy-efficient models; and switch to energy-efficient heating systems such as geothermal or heat pumps.
