Gallery: Study Shows Photovoltaics Beat Biofuels at Converting Solar En...


When it comes to transforming the sun’s energy into commuter miles, it looks like photovoltaics beat out our best biofuels. A recent study published in the journal Environmental Science & Technology investigated the relative efficiencies of the two technologies by focusing on traditional methods of turning corn and other plants into ethanol, turning energy crops into electricity, and using photovoltaics to directly convert sunlight into fuel. The team found that PV’s were far more efficient at creating “sun-to-wheels” energy for vehicles.
