This is a great tale, but I don’t believe it. The article [

Vol. 5, No. 4, pp. 10-11] implies that insulation and airsealing dropped 30 tons (106 kW) of peak load from this 17,000 ft2 (1,600 m2) building. Nor do I believe the peak load of only 20 tons (70 kW) for this building. Indiana has hot... Read more

The United States took a surprisingly strong position on cutting greenhouse gas emissions this summer at the Second Conference of the Parties to the Framework Convention on Climate Change (COP2) in Geneva. On 17 July, Undersecretary of State Timothy Wirth announced that the U.S. will seek an amendment to the existing treaty to create “binding”... Read more

Both Schuller and NRG have been leaders in improving the environmental characteristics of... Read more

Now that we at

EBN have finally the caught up with the trends and have created our own website, we can slow down long enough to ask: Why are we doing this, anyway? Didn’t we have enough to do just publishing on paper? At least the courts have struck down Internet censorship, so we don’t have to worry about getting in trouble for... Read more

Nuclear proponents have often pointed to the low electricity prices in France as evidence that high reliance on nuclear power keeps electricity prices low. But by comparing

pre-tax electricity rates, that claim is dispelled. According to the May/June issue of

World Watch Magazine, the three European countries with the lowest pre... Read more

A primary weakness of light-gauge steel framing for houses has been its severely compromised thermal integrity. In general, the simplest way to get a steel-framed wall to perform like a 2x6 wood-stud wall is to use 2x4 steel studs and add 2” (50 mm) of insulating foam sheathing. Now, researchers at Oak Ridge National Lab (ORNL) are seeking a... Read more

I’ve worked the last 25 years on developing parts of what is now called “Eco-design,” under the belief that healthier buildings, lower energy use, and less ecological impact were important. This was only to discover recently that all this time I was still looking at things in isolation rather in their ecological interconnectedness!

The pilot lights on gas-fired fireplaces waste a lot of energy. That’s one conclusion of a recent study by Skip Hayden of the Combustion Gas Research Laboratory of CANMET and Consumers Gas, a major Canadian gas utility. Fifty-two homes with significant use of gas fireplaces were surveyed; 38 of these had continuous pilots. In the homes with... Read more

Scientists at the National Renewable Energy Laboratory (NREL) in Golden, Colorado, have achieved a new world record in thin-film photovoltaic cell efficiency. A record 17.7% “sunlight-to-electricity” efficiency was achieved with a compound semiconductor called copper indium gallium diselenide. While this efficiency is 60% higher than the... Read more
