The “Rebound Effect” Falls Flat
Prompted in part by a recent article in the New Yorker, there’s been a lot of attention to the rebound effect lately. The theory is that increased energy efficiency in effect makes energy cheaper (as measured in cost per unit of benefit), so people actually consumer more energy. The empirical evidence is that this is …

Newer buildings in California put more of a strain on the electric grid than do older buildings. That is the apparent conclusion of a new paper written by Howard Chong through UC Berkeley’s Energy Institute at Haas. The strain comes in the form of a greater “temperature response” – an increase in temperature on a …

It’s good to know that there’s still someone who isn’t afraid to stand up for the use of obsolete technologies and the right of every citizen to overpay for electricity.
CONTINUE READINGChilly in Baltimore: Energy Efficiency and Wind Power
I heard an interesting story on NPR today about “district cooling” in which a company in Baltimore uses ice to produce chilled water, which is transported to a number of building in the city for supplemental cooling. What really struck me as cool about this (sorry about the pun) is the fact that this system …

CONTINUE READINGOne More Try This Year for a National Renewable Electricity Standard
Is something, in terms of a federal renewable standard, better than nothing? There is new talk of setting a national renewable electricity standard before this session of Congress ends, due to the introduction of S.3813, this week. This Bingaman-sponsored bill echoes an earlier proposal that can best be described as imposing a standard of modest …

CONTINUE READINGWhat a Waste of Energy
The Lawrence Livermore National Laboratory has issued its annual snapshot of our national energy use, based on data collected by the Department of Energy’s Energy Information Agency. The good news is that we used less energy in 2009 than we did in 2008 (almost all of the savings probably attributable to the still-weak economy). The …

CONTINUE READINGThe Nano Road to Energy Efficiency
Science Daily reports: Researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a new way to apply nanostructure coatings to make heat transfer far more efficient, with important potential applications to high tech devices as well as the conventional heating and cooling industry. These coatings can remove heat four times faster …

Yesterday, the Federal Housing Finance Administration, the agency that regulates bankrupt mortgage insurers Fannie Mae and Freddie Mac, issued a letter effectively destroying the promising energy efficiency and renewable energy financing program called Property Assessed Clean Energy (PACE). I blogged about Fannie and Freddie’s lender letters on the PACE program a few weeks ago. PACE …

CONTINUE READINGRetrofitting homes to make them more energy efficient
When we ponder ways to reduce the greenhouse gas emissions that cause climate change, nothing says “low hanging fruit” more than retrofitting our existing homes and small businesses to make them more energy efficient. Energy use from commercial and residential buildings accounts for 22 percent of California’s greenhouse gas emissions. But relatively simple steps like …
