Why can’t a nuclear power plant get built without the taxpayers promising [...]

Smart windows save energy

NREL color changing window

Researchers at the National Renewable Energy Laboratory are working on “dynamic windows” that change shadings so as to better regulate energy and efficiency.

Buildings consume 40 percent of the nearly 100 quadrillion Btus (quads) of energy the United States consumes annually. Conventional clear windows account for about one-tenth of the [...]

Glycerin byproduct from biofuel refining now being reused

Prodigious amounts of glycerin are produced as a byproduct of biofuel, and sometimes was being landfilled. However, scientists now have devised a multitude of ways it can be used and reprocessed.

Waste glycerin can be made into a profit center, yielding high-value chemicals (alcohols and acids) that can be used to make fabrics, insulation, and [...]

Using waste heat energy for industrial-scale air conditioning

New technology from China use multiple forms of waste heat to heat water. Absorption chillers then use that heat to create AC cooling. This saves considerable money and uses no fossil fuels.

Energy-aware Internet routing coming soon

Researchers from MIT, Carnegie Mellon University, and the networking company Akamai recently published results from a study that suggest big Internet companies could save up to 40 percent on their electricity bills by using an algorithm to send Internet traffic to data centers where electricity is less expensive.

Wow. Imagine what such a smart grid [...]

Chevy Volt’s 230 mpg in perspective

GM, using EPA standards, predicts that the Chevy Volt will get 230 mpg– an astounding figure for a big-six vehicle.  It’s commonly compared with Toyota Prius’s 48 mpg.  But that’s only because several higher mileage cars, like the 70 mpg VW Polo, aren’t sold in the U.S.

The mpg figure makes the [...]

USPS green roof

This new 2.5 acre green roof in NYC is a park for employees, saves energy by providing more insulation, and reduces water runoff. The plants are drought resistant and watered by collected rain.
