...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 with solar panels could provide a cheap, sustainable light source that doesn't need a traditional power grid...
...Sunni and Shi'ite massacres have destroyed order in a city famously pacified by counterinsurgency tactics in 2005. Bush's indifference to reality in Iraq is not an isolated case. It is the modus operandi of his Administration. The indifference of his Environmental Protection Agency to the dangers of carbon dioxide emissions was rejected by the Supreme Court on April...
That would be good for everyone. Last year alone, China added 102 gigawatts to its electrical grid--roughly twice the total capacity of California's--and about 90% of that came from carbon-belching coal plants. Geothermal energy can at least make a start on cleaning up this mess. The China Energy Research Society expects 110 gigawatt hours (GWh) to be produced through geothermal power nationally by 2010, out of 2.7 million GWh in total. 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...
...strategies they have identified could prevent a total of 25 billion tons of emissions by 2056. (We're now adding 7 billion tons annually, and that figure would double by 2056 without some action.) They are all so-called stabilization wedges, which lower the angle of the line representing carbon-emissions growth and together would reduce CO2 emissions enough to stabilize the carbon concentration in the atmosphere. Efforts to reduce energy use form one kind of wedge. So does improving power plants. Another wedge addresses alternative energy...
...codirectors of the Carbon Mitigation Initiative at Princeton University, Socolow and Pacala oversee research exploring the potential of wind, solar, hydrogen, geothermal and, yes, even nuclear power that should contribute to several of the wedges...
