The numbers I've seen say that glass uses less energy than plastic. 100% recycled aluminum beats glass, but a more realistic mix, or virgin aluminum, uses more energy than glass.

Glass uses less energy per kilogram by a factor of 3 or so, according to your source. But plastic bottles use an order of magnitude or two less material, so still use less energy per bottle.
