Scheduled to be up and running by 2013, this particular alcohol-powered project is Scotland’s first whisky-fueled energy project that will provide electricity to the public.

Sixteen whisky labels located in Speyside, Scotland—including Glenfiddich, Chivas Regal, and Famous Grouse—will contribute material to the new power plant. They’ll transport their  spent grains (or draff) from the distilleries to the biofuel plant, where it’ll be combined with wood chips and burned, generating over 7.0 MW of power. This energy output—about the same as two large wind turbines—is expected to power at least 9,000 homes.
