If you are looking for a great source of environmental news and views you can use then look no further than Grist Magazine the legendary "beacon in the smog" which gives you all the news you need but with a dose of humor which is much appreciated when the discussion turns to things like global warming.
Anyhow they featured a story on famed record label Sub Pop and their becoming "the first Green-e certified record label company in the United States." What they have done is bought enough Green-e certified Green Tags, also known as renewable energy credits which will enable the company to be powered by environmentally friendly energy sources 100%.
What these Green Tags do is fulfill Sub Pop’s energy requirements by using environmentally friendly renewable energy sources such as wind, solar, biomass and geo thermal in place of the more traditional and destructive energy sources such as electricity drawn from coal fired plants or nuclear.
