Binge drink, save the environment

The Sierra Club has an interesting report on how to pick a "green beer"... there are apparently multiple ways to do this: either choose a brewery which uses renewable energy and recycles its beer waste, drink local beer which does not take carbon emissions to transport, or just buy a keg which reduces the amount of packaging the beer comes in and can be recycled (and usually is, since you get some cash back for your keg deposit).

So really, the right thing to do for the environment is to install a keg refrigeration system that will allow you to drink a keg over time... except that would use a lot of energy, leaving the only real option to drink excessively or throw a lot of parties.

But if you go the innovation route try New Belgium or Brooklyn breweries for using renewable power, or Foster's which actually manages to recycle its beer wastewater and feed it through a fuel cell, producing enough electricity to power a house. Any guesses on how many times the amount of power the fuel cell produces would be spent on transporting that beer from Australia into your refrigerator?
