brooklyn brewery is apparently run by a bunch of hippies.
Brooklyn Brewery isn't equipped with wind turbines on the warehouse roof, however. Instead, the brewery pays a premium rate to Con Edison so that the 285,000 kilowatt-hours it uses off the grid every year is replaced by energy produced at a wind farm located in Madison County, in upstate New York.
It also pays farmers in New Jersey to swing by and pick up the "spent grain" -- the remaining husks that are left over after brewing. The farmers then feed the nutritious grains to their livestock, making good use of Brooklyn Brewery's waste.
ok, here we go. BEER WILL SAVE THE WORLD!!!
After producing its libations, New Belgium puts its waste water inside closed pools filled with anaerobic bacteria. The microbes feed on the water, rich in nutrients from the brewing process, and produce methane gas, which is then pumped back to the factory where it becomes electrical and thermal energy.
