Leave it to Dyson to come up with the most beautiful, (pricey), and energy efficient fan. Using an airfoil-shaped ramp (like a cross-section through an airplane wing), airflow is amplified 15 times. Apparently this creates "smooth, powerful airflow," with no need for fast-spinning blades. Up to 5.28 gallons of air per second is drawn in by an energy efficient brushless motor....read more
On a visit to Home Depot in Alexandria, VA yesterday, President Obama said retrofitting homes to improve energy efficiency is "sexy". What's sexy about it, he said, is "saving money". Ohhkayyy. We can think of a few sexier things than saving money - like, for example, grilled cheese sandwiches, or clipping our nails - but anyway. Whatever floats your boat, Mr. President.......read more

But, according to a newly released report from the Energy Efficiency Council (EEC) of Australia, it's not nearly as important as taking measures to improve energy efficiency. "The International Energy Agency estimates that energy efficiency will deliver 65 per......read more
Italian lighting manafacturer ewo develops and produces advanced lighting systems for public spaces.

No more Mr. Nice Guy: "End of Nature" author Bill McKibben says it's time to get pissed off about climate......read more
Cars have miles-per-gallon ratings, neighborhoods have walkability rankings, and people have carbon footprint calculators. What's up with homes then? Why isn't there be a comparable, affordable way to size up your home's energy performance? Well, now there is. The Department of Energy just released a program called the Home Energy Score that shows the energy efficency of a home on......read more
DIY Kyoto's flagship product, the Wattson 01, is a sleekly-designed energy meter that measures your electricity use and projects energy expenses. Like most home energy meters, the Wattson consists of three devices: a magnetic clamp that attaches to your home energy meter, a battery-powered transmitter that attaches to the clamp via a short cable, and a display unit. The difference is in the......read more
French designer Mathieu Lehanneur has set a new design standard for home energy monitoring systems. Created for Schneider Electric, Efficient Home debuted at the St-Etienne Design Biennale last week. The quirky collection is conceived as a series of symbols that act like an energy alphabet, complementing each other in various combinations. The objects, which include a temperature sensor,......read more
Believe it or not, Capitol Hill is a hotbed of eco efficiency. The Christmas tree out front of the Capitol is outfitted with energy-saving LED lights. Inside, staffers print with recycled paper and eat with compostable utensils under the glow of eco-friendly CFL lights. Most (but not all) of these green measures can be attributed to Nancy Pelosi's Green the Capitol program, which replaced a......read more
