This year brought sparse positive economic news, as soaring energy costs drove steep price increases and the mortgage meltdown stalled residential construction and later commercial construction with the credit crunch.
Earlier this year, the US Department of Energy (DOE) launched Commercial Lighting Solutions, an interactive Web tool that provides lighting templates, supported by construction documents, that can help commercial building owners achieve desirable lighting quality while improving lighting efficiency
DTE Energy is helping Detroit Edison customers make their homes more energy efficient with discounts of up to 50 percent on compact-fluorescent lamps (CFLs). The specially priced bulbs are available now through DTE Energy at several area retailers for as little as 99 cents apiece.
