Yup pardner, in what is believed to be the largest ever purchase by an American company, Well Fargo figures on buying 550,000 megawatt-hours of renewable energy certificates (from windpower). This will be the equivalent of 40% of their electrical energy consumption. Or put another way, it should have the equal environmental benefit of taking 75,000 cars off the road. (No mention of how many 6 horse stagecoachs that might equate to though.) This isn't the Californian-based banker's only green endeavour. In August of this year they put up finance for their 12th LEED certified building project. Plus they have a raft of their own eco programs, including a downloadable 20 page PDF that helps investors understand the renewable energy market. It includes all the usual suspects like solar, wind, hydro, biomass and such forth. (Was, though, a little surprised to see nuclear also to make the cut.) And at one point Business Ethics magazine even listed the bank amongst the top 10 "Best Corporate Citizens" in the US. ::Wells Fargo, via Mercury News.
