Green Oxford turning sludgy grey?

According to the BBC, Oxford University (where I've heretofore been proud to be a long-term part-time visitor in Astrophysics), presently the fourth largest consumer of green electricity in the UK is considering moving back to fossil fuels. More specifically, it's hired `"energy-purchasing consultants" Epal' (whom I can't find anywhere on the web, strangely) to investigate its options. Despite all the talk about top-up fees and science funding in the UK, Oxford (and especially its Colleges) is one of the wealthier entities in the UK, and it should use its cash to worry about the long term, not the bottom line.
