...soon followed up the blue LED with the first bright green and white LEDs. An LED is a semiconductor that generates light, but very little heat, when an electric current is passed through it. Different semiconductor materials produce different colors; Nakamura used gallium nitride, which generates blue and white light. The resulting LEDs use as little as one-seventh the energy as an incandescent bulb and can last about 100 times as long, up to 100,000 hours. If they were widely used, LEDs could lead to enormous energy savings and carbon-emissions reductions. In the developing world, LEDs paired...
...When I first traveled to the Kurdish North in August of 2004 to escape the heat and violence of Baghdad, the so-called "Switzerland of Iraq" was disappointing in just one respect: summers on the high plains of Erbil are almost as scorching. Otherwise, Kurdistan was a refuge. In Baghdad, journalists had begun hiring security entourages and erecting guarded compounds. Up north in Erbil, as a visiting American, I was practically given keys to the city. I did my reporting by foot or hailed taxis from the street, spent my evenings in beer gardens or pizza parlors, and slept...
JUSTICE JOHN PAUL STEVENS, writing for the majority in the Supreme Court's 5-4 ruling that found that the Environmental Protection Agency violated the Clean Air Act by not limiting heat-trapping greenhouse gases in vehicle emissions; the court said the EPA has the power to regulate those pollutants...
...most polluted cities in a very polluted country, partly as a result of the air-fouling coal that's burned to generate much of its power. The air in Reykjavík, by contrast, is crystal clear, because nothing is burned there. Iceland's capital gets 100% of its heat and 40% of its electricity from geothermal power. (The rest comes from hydropower.) The same forces that have scattered no fewer than 130 volcanoes across the tiny country bring molten rock relatively close to the surface everywhere. When this encounters underground water, it generates steam, which is tapped to produce clean...
...That's a tiny slice, but energy experts believe China has the potential to do much more. "There are geothermal resources in almost every province in China," says Ingvar Fridleifsson, director of the United Nations University Geothermal Training Program in Reykjavík. Geothermal pumps will even be used to heat and cool some of the venues at the 2008 Olympic Games in Beijing...
