ENERGY STAR matters
- As of December 2012, families and businesses have realized estimated savings of more than $239 billion on utility bills and prevented more than 1.9 billion metric tons of greenhouse gas emissions over the past two decades. The interplay of government, business, and market forces brought together through ENERGY STAR has changed the energy efficiency landscape.
- By choosing ENERGY STAR qualified products, the typical household can save $146 to $501 per year – while improving home comfort and helping the environment.**
**The U.S. Environmental Protection Agency and the Department of Energy. Savings estimates based on an even mix of one- and two-story detached homes of 1700 or 2600 sq. ft. respectively, with 15% of their floor space in windows that are equally distributed across compass directions. Heating and cooling systems are modeled as either natural gas heat with electric air conditioning or electric heat pump, according to the regional breakdown reported in the Energy Information Administration's (EIA) 2005 Residential Energy Consumption Survey. Estimates use the EIA's 2006 average natural gas prices and the 2007 electricity prices. Actual savings will vary by local climatic conditions, utility rates, and individual home characteristics.
