A Voluntary Performance Label for Industrial Equipment Is Bringing Together Manufacturers and Efficiency Experts
Most of us involved in energy efficiency have realized at one time or another that there are greater opportunities to save energy through system optimization than through improvements to the efficiency of an individual device. A good way to visualize this is to picture a well-designed pump driven by a high-efficiency motor pumping water through a mostly closed valve that not only wastes most of the electricity going into the motor, it causes backpressure on the pump that will cause it to wear out quicker.
Washington, D.C.—A new analysis of devices and equipment commonly found in U.S. homes and businesses concludes that these products, with more than 2 billion in use, consume more energy each year than many large countries use to power their entire economies.
On a personal note, I learned about an additional benefit of investing in a super-efficient refrigerator. About two months ago my wife and I finally bought a new refrigerator—the new Whirlpool model that is the most efficient on the market.
The energy bill provides tax credits for heavy-duty hybrid vehicles in the period January 1, 2006 through December 31, 2009. The credit amount depends on the weight class of the vehicle, its fuel economy relative to a comparable conventional vehicle, and the incremental cost.
A hybrid vehicle's incremental cost is defined as the amount by which the manufacturer's suggested retail price of the hybrid exceeds that of a "comparable" vehicle; but it is capped by class:
