Wondering if that beer on your counter was made with renewable energy? The Environmental Protection Agency might be able to tell you. That's because the agency just released its list of the top 20 organizations running on "green power", or energy from solar, wind, and biogas sources.
The IT industry is known for its electricity-sucking tendencies and carbon emissions, which is why Dell's announcement that it now sources 26% of its electricity from renewable sources—up from 20% in 2008—is so admirable. The company now powers nine facilities in the U.S.
Lünen, Germany is about to get a whole lot smellier now that it's set to become the world's first town to be powered by animal waste. The town will use biogas from cow and horse manure to power a biogas plant, that will produce 6.8 MW of power—enough for 30-40% of Lünen's overall needs. Biogas technology isn't new, but this is the first time it will be used to power a town.
