...approaching 2,000°F, performing on par with what is called Advanced Wood Combustion (AWC) technology developed in Europe. "AWC is so clean and safe that AWC systems are commonly deployed in the midst of picture-perfect European towns and villages," says Daniel Richter, professor of soils and forest ecology at Duke University. They are different from ordinary plants that generate electricity by burning wood. In a piece in the journal Science last March, Richter wrote that 90% of the solar energy stored in wood is transformed into heat and power by AWC technology, compared with...
...Schools is a six-state program funded by federal and state money that helps to retrofit school boilers, switching them from burning oil and gas to wood. Starting in Vermont, it spread westward, giving budget-strapped local districts huge savings and a way to cut into buildups of forest deadfall that might otherwise fuel wildfires. However, it is now almost out of federal money. Even after the program helped retrofit heating systems in 10 Montana schools, the last state legislature refused to renew appropriations...
...that's rarely how it works in most biofuel production today. Instead, a long-standing forest might be clear cut in Indonesia and replaced with a plantation of palms to make biodiesel. That's where the accounting error crops up: we should assess the carbon lost in deforestation when we measure the greenness of biofuels, but that's not how it works under Kyoto, which simply exempts all CO2 emissions that come from using biofuels. CO2 emissions resulting from deforestation or other changes in the way we use land are not evaluated at all. The result is a huge...
...emissions and comply with a tightening carbon cap. One study estimates that if the world were to meet a 50% "cut" in global greenhouse gases by 2050 under the current calculations, the necessary biofuel-crops expansion would be large enough to displace 59% of the world's natural forest cover - which would release an additional 9 billion tons of CO2 a year. "Carbon capture and storage, solar power, electric batteries - all of these alternatives have serious costs," says Searchinger. "But if you can just use up the world's carbon in forests to meet your cap, that turns...
Riding high on its own top ten status, the Crimson was brought down to Earth with a 1-0 loss at Wake Forest. Harvard followed up that loss with a 4-0 drubbing at the hands of then-No.17 Connecticut...
