Bloomberg New Energy Finance Index (CREX)
Bloomberg New Energy Finance Index. The CREX participants are ranked based on the percentage of renewable electricity procured for their own use in 2011, calculated by dividing renewable electricity consumption by total electricity consumption for the period. A company with a 100% score is one that meets all of its electricity needs from renewable sources. If two or more companies have the same percentage score, they have an equal ranking even if they consume different total amounts of renewable energy.
