“Conserving energy is cheaper and smarter than building power plants” (Dr. Arthur Rosenfeld).

The watt. The volt. The ohm. All electrical terms are named after famous engineers and physicists from the 18th and 19th century. Now, an acclaimed 20th century scientist is lending his name to a new unit of energy savings – the ‘Rosenfeld.’

The proposed term – a ‘Rosenfeld’ – would represent the electricity savings of 3 billion kilowatt-hours per year — the annual output of an existing 500 megawatt coal-fired power plant – and avoid generating three million metric tons of CO2 emissions. The new energy-savings measurement term was authored by 54 scientists from 26 research institutions and announced in the peer-reviewed journal Environmental Research Letters.

“The Rosenfeld” Named After California’s Godfather of Energy Efficiency.

With a decades-long career in energy analysis and standards, Rosenfeld is often credited with being personally responsible for billions of dollars in energy savings.

How to cut energy use, carbon? Do it – One “Rosenfeld” at a time.

Arthur Rosenfeld, who recently retired at the age of 83 after two five-year terms on the California Energy Commission, led the way in helping the state set its first-ever energy standards for household appliances and buildings. His mission as an energy-efficiency evangelist was launched in 1973 during the OPEC oil embargo … rather than rail on the oil producers, he reasoned, wouldn’t it be better if the US could find ways to stop wasting so much energy?

His impact on California’s per capita electricity consumption, which has remained flat since the mid-’70s, has long been dubbed the “Rosenfeld effect.” And he himself coined “Rosenfeld’s Law,” which asserts that the amount of energy required to produce one dollar of economic output has decreased by about 1 per cent per year since 1845.

Arthur H. Rosenfeld, Ph.D. was originally appointed to the California Energy Commission by Governor Gray Davis in April 2000. The Commissioner was reappointed by Governor Arnold Schwarzenegger January 26, 2005. The five members of the Energy Commission are appointed by the Governor to staggered five-year terms and requires Senate confirmation. By law, four of the five members of the Energy Commission have professional training in specific areas – engineering or physical science, environmental protection, economics, law, and one commissioner from the public-at-large. Commissioner Rosenfeld filled the physical science position until his retirement in January 2010.

Commissioner Rosenfeld was presiding member of the Research, Development and Demonstration Committee and the Dynamic Pricing Committee (Ad Hoc Committee); and was the second member of the Energy Efficiency Committee.

Art Rosenfeld received his Ph.D. in Physics in 1954 at the University of Chicago under Nobel Laureate Enrico Fermi, and then joined the Department of Physics at the University of California at Berkeley. There he joined, and eventually oversaw, the Nobel prize-winning particle physics group of Luis Alvarez at Lawrence Berkeley National Laboratory (LBNL) until 1974. At that time, he changed his research focus to the efficient use of energy, formed the Center for Building Science at Lawrence Berkeley National Laboratory, and led it until 1994.…………
