BackgroundBackground

Electricity used for lighting in residential, commercial, Electricity used for lighting in residential, commercial, and manufacturing = 16% of total U.S. electricity and manufacturing = 16% of total U.S. electricity consumption = 588 billion kWhconsumption = 588 billion kWh

Use and cost of electricity is growing Use and cost of electricity is growing

This poses challenges to tight local budgets, the grid, This poses challenges to tight local budgets, the grid, and household incomesand household incomes

More efficient use of electricity = saving local More efficient use of electricity = saving local government and taxpayer dollars = reducing our region’s government and taxpayer dollars = reducing our region’s carbon footprint carbon footprint
