Dim Bulbs (The Sequel)

I did a post last November about the surprising tea party anger regarding energy-efficient light bulbs.  The furor seems to be continuing.  Here are some quotes from Republican Senators courtesy of EE News: “People in Idaho are just astonished that the federal government is telling them what kind of light bulb to put in their …

Michele Bachmann’s Unconstitutional Light-Bulb Bill

Congress can repeal the light bulb requirement (or not). It can mandate that an executive agency like DOE or EPA decide the three issues specified by Bachman. But Congress can’t make the validity of the light bulb requirement turn on a determination by GAO.

A Roadmap for Sustainable Consumption

Individual consumption – including household heating and cooling as well as non-business transportation – creates roughly one-third of U.S. energy use and carbon emissions. It would feasible to reduce these emissions by twenty percent in a decade: there is a lot of low-hanging fruit yet to be picked. A range of individual actions, while seemingly …

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 …

Buidlings and Energy Efficiency — Just Being New Isn’t Enough

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 …

Dim Bulbs

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.

Chilly in Baltimore: Energy Efficiency and Wind Power
