Is biochar a solution to climate change? Maybe, or maybe not.
The EPA is waffling on the mandate, big oil is suing, biofuels companies are pressing for E15, pols want probes … it’s crazy times for the ethanol industry.

Cellulosic ethanol, the stuff that doesn’t use food crops, makes a big advance with the official opening of a plant in Italy.
An audit of U.S. advanced biofuels support wants to know: Where are the promised commercial-scale plants making cellulosic and bio-based hydrocarbon fuels?
Researchers now say their study of giant panda feces has yielded some 40 microbes that could help turn lignocellulose material into biofuel.
Whether what propels a car is electricity, liquid fuels, natural gas, or hydrogen, the critical impacts all occur far from the car itself at locations where fuels originate and natural resources are exploited.
