Energy Star Appliances May Not All Be Efficient, Audit Finds
WASHINGTON — The Energy Department has concluded in an internal audit that it does not properly track whether manufacturers that give their appliances an Energy Star label have met the required specifications for energy efficiency.
Some manufacturers could therefore be putting the stickers on unqualified products, according to the audit, by the Energy Department’s inspector general, Gregory H. Friedman.
The Energy Star program, jointly managed by the Energy Department and the Environmental Protection Agency, has benefited from a renewed emphasis by the Obama administration, as a mechanism for reducing the waste of energy and curbing resulting greenhouse gas emissions. Under the federal stimulus bill, $300 million will go to rebates for consumers who buy Energy Star products.
Some consumers choose energy-efficient appliances for the same reason they might choose a car with good fuel economy: to save money or reduce the environmental impact.
Teams from the Energy Department and the E.P.A. oversee different categories of products. Last December, the environmental agency’s inspector general said the Energy Star ratings for products it oversees, like computers and television sets, were “not accurate or verifiable” because of weak oversight by the agency.
The Energy Department vowed then to scrutinize its performance in evaluating the products that it oversees, like windows, dishwashers, washing machines and refrigerators.
The new audit, a copy of which was obtained by The New York Times, indicates that the Energy Department has also fallen far short. Those shortcomings “could reduce consumer confidence in the integrity of the Energy Star label,” according to the department’s inspector general. The audit is to be submitted to Energy Secretary Steven Chu this week. While the Energy Department requires manufacturers of windows and L.E.D. and fluorescent lighting to have independent laboratories evaluate their products, the report said, companies that make refrigerators, washing machines, dishwashers, water heaters and room air-conditioners, which consume far more energy, can certify those appliances themselves.
