An inexpensive combination of two metals common in the manufacture of computer chips can generate hydrogen from water, using only sunlight as an energy source. If the process can be made commercially viable -- and the simplicity and cost suggests it might -- it would mean yet another way to produce energy directly from sunlight, and a potential source of hydrogen for the kind of fuel cells that power both buildings and vehicles.
After suffering recalls, an earthquake, and a tsunami, the maker of the ever-popular Prius pins its hopes for rebirth on a new green model: the Camry Hybrid.
So last week Irene was all like, "HERE I AM! I'm going to rock you like myself!" And off the coast of Jersey (where else?) the U.S. Navy's PowerBuoy was like "bring it!"
A stadium-sized balloon tied down by a giant garden house could mimic the cooling effect of volcanoes, say British researchers.
Workers broke ground this week in Seattle on a six-story building that will generate its own power, collect and reuse rainwater, compost its sewage, and depend on daylight instead of halogen lamps. Its owner, the Bullitt Foundation, which supports work in sustainability, set out to build the greenest building on Earth. We'd say they're earning that title.
Just because your lungs are blackened doesn't mean you can't be green. San Diego-based company Greenbutts makes cigarette filters that not only biodegrade, but sprout when buried into what have to be the world's least healthy plants.
Is continued economic growth inevitable and necessary to drive improvements in the human condition? Or is continued economic growth impossible, constrained by biophysical limitations? I let the two sides battle it out in my brain.
When state leaders react to mild criticism of coal like it's an assault on the dignity of all West Virginians, they're doing more than overreacting: They're cheating the Mountain State out of a clean energy future.
Less-educated workers with green jobs get higher wages than their peers with other low-skill jobs. Could it be because more green jobs are union jobs?
