In most homes, utility bills are affected by a complex set of factors. Regional climate, orientation and exposure to natural light, and building materials are just a few of the many. For most homeowners, saving money by cutting down on electricity costs first involves the complicated task of assessing where energy waste is occurring.
Here, the Home Energy Saver web site can prove especially useful. In addition to offering practical energy saving advice, the HES allows users to enter detailed information about their homes and provides an instant usage comparison with other homes nearby. This data is also used to render personalized recommendations for home efficiency upgrades along with the corresponding payback period for each investment.
