FREE FRICTION CD FROM GENERAL MAGNAPLATENew unit of energy efficiency: The Rosenfeld
Now you can tell people how much energy your newest gizmo saves, expressed in Rosenfelds. It is hoped that the Rosenfeld - named after the "father of energy efficiency" Dr. Art Rosenfeld - will help standardize references to “energy saved,” rather than such variable calculations as “avoided powerplants” or “cars off the road.” Arthur Rosenfeld is an acclaimed high-energy physicist and researcher/educator for Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley.

The GAO formed four fake companies that created 20 bogus energy-efficient products, several of them outrageous on their face. Of the 20 fictitious products, 15 were granted Energy Star status by the Environmental Protection Agency and the Dept. of Energy, which jointly run the program. READ MORE Read More

Water heaters get tougher efficiency standards
New standards from the DoE tighten up minimum conservation standards for three types of residential heating products, which account for about 18% of energy use in homes. The standards will significantly cut energy consumption by these products, says DoE, and will demand large electric storage water heaters use 47% less energy and large gas water heaters use about 30% less.
