Burn almost any kind of organic material - corn husks, hazelnut shells, bamboo and, yes, even chicken manure - in an oxygen-depleted process called pyrolysis, and you generate gases and heat that can be used as energy. What remains is a solid - biochar - that sequesters carbon, keeping CO2 out of the atmosphere. In principle, at least, you create energy in a way that is not just carbon neutral, but carbon negative...
...electricity consumption to his own theoretical ones, Lovins’ presentation, “Profitable Solutions to Climate, Oil, and Proliferation,” focused on reducing costs as a means to help the environment. Certain companies, driven by opportunities for increased profit, have shown that cutting back CO2 emissions is possible, he said. IBM and STMicroelectronics were able to cut their emissions by 6 percent while looking for ways to reduce costs. Similarly, when the Dow Chemical Company invested in efficiency rather than buy more fuel, it ended up with a $3.3 billion profit. From a consumer?...
...interest in Silicon Valley science fiction, the most cost-effective green technology can be found in our own homes, simply by improving the energy efficiency of our houses and apartments. On average, heating an American home with natural gas creates about 6,400 lbs. of CO2 a year; using electricity will produce about 4,700 lbs of emissions. Both numbers can be larger if you live in a cold part of the country. The problem is that many American houses are poorly constructed and insulated, leaking heat in winter and cool air in the summer - and that's not cheap...
...Right now, however, there is no definition of BACT for CO2, and environmentalists estimate it will take six months to a year to figure that out. In the meantime, all other coal plants in the permitting process, or stuck in the courts, will be frozen. Over the longer term, it's possible that new coal plants may be impossible to certify at all until a technology exists to greatly reduce or sequester carbon emissions from coal plants - and currently none has been proven. "The decision says the EPA can't ignore CO2," says Nilles...
...That effectively punts the future of coal in America to President-elect Barack Obama's incoming Administration. It's not yet clear how he'll act, but his renewable energy advisor Jason Grumet has said that Obama would be willing to use the EPA to directly regulate CO2 - something President George W. Bush has refused to do. "This lays the groundwork for Obama to move quickly to put in place a regulatory system and begin to achieve CO2 reduction and build that clean, 21st century economy he talks about," says Nilles. Obama's position on coal isn't exactly clear...
