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.

I think a lot of people are Ok using more energy to recycle glass (if true), instead of having trillions of pieces of plastic filling up the planet.

I doubt that selling Dasani water in aluminum cans in the Northeast US is going to move the needle on global plastic pollution, with the entire US accounting for less than 1% of plastic pollution (below countries such as North Korea and Algeria [1]) despite having 4% of the population and 24% of GDP.

Breaks down better when it escapes into the environment than plastic does.
