Report shows bioelectricity yields more miles per acre than ethanol

It has been suggested before that it just might be more efficient to turn crops into electricity than biofuel, and here's a study that proves that to be the case.

According to the study co-sponsored by the Carnegie Institution for Science, "Bioelectricity was the clear winner in the transportation-miles-per-acre comparison, regardless of whether the energy was produced from corn or from switchgrass, a cellulose-based energy crop. "

"The internal combustion engine just isn't very efficient, especially when compared to electric vehicles,” says Elliott Campbell, lead author and professor at UC Merced. “Even the best ethanol-producing technologies with hybrid vehicles aren't enough to overcome this."

“Some approaches to bioenergy can make climate change worse, but other limited approaches can help fight climate change,” says Campbell. “For these beneficial approaches, we could do more to fight climate change by making electricity than making ethanol.”

Very useful information provided.

The very severe problem with this study is that it does not account for the embodied energy in internal combustion automobiles. The cost and energy necessary to retrofit existing cars to run on ethanol pales in comparison to the cost of building new electric cars and an infrastructure to power them
