Counting the Sins of Chinese SynGas

Heavy water use, threats of tainted groundwater, and artificial earthquakes are but a sampling of the environmental side effects that have tarnished North America’s recent boom in natural gas production via hydraulic fracturing or fracking. No surprise then that in European countries such as the U.K. that are looking to frack for cheap domestic gas, the environmental protesters often arrive ahead of the drill rigs.

But countries seeking fresh gas supplies could do far worse than fracking. So say Duke University researchers who, in today’s issue of the research journal Nature Climate Change, shine a jaundiced spotlight on China’s plans to synthesize natural gas from coal. Nine synthetic gas plants recently approved by Beijing would increase the annual demand for water in the country’s arid northern regions by over 180 million metric tons, the Duke team concluded, while emissions of carbon dioxide would entirely wipe out the climate-cooling impact of China’s massive wind and solar power installations.

Subversive Additives to Save the “Cash-for-Clunkers” Bill

Bike parking in Freiburg Germany COPYRIGHT P FAIRLEYProspects for a “cash-for-clunkers” bill to stimulate new car sales in the U.S. are dimming amid dissatisfaction with the law’s slim environmental benefits. There are some creative options available to green the bill.

As Energywise reported, representatives in the House led by Michigan Democrat John Dingell converged on an automotive scrappage bill earlier this month that would provide cash vouchers worth up to $4,500 to buyers of new cars and trucks that get at least 22 miles to the gallon if they scrap an old one that gets no more than 18 mpg. Duke University researchers estimate that the reduced energy consumption from such a swap would make up for the energy required to manufacture the vehicle. But some senators were hoping for a more.

California Senator Dianne Feinstein is leading the charge. Continue reading “Subversive Additives to Save the “Cash-for-Clunkers” Bill”
