The recently announced offer by Wall Street financiers and private equity firms to buy Texas electric utility TXU is not your typical leveraged buyout, by any definition. It is the largest LBO in history -- but that only makes it interesting as an answer to a Trivial Pursuit question a few years from now (until it is supplanted by a larger deal). What truly makes one sit up and take notice is the inclusion of prominent environmental groups in the deliberations that culminated in the TXU offer by Texas Pacific Group and Kohlberg Kravis Roberts & Company (KKR). I address the significance of these events, and the interesting juxtaposition of this green LBO with Al Gore's recent Oscar for "An Inconvenient Truth", in my most recent column for Ethical Corporation.
