What's with Wal-Mart?

It's positively eerie. Just image cultivation? Actual corporate responsibility? Time will tell. But they have a huge request for proposal out to convert their facilities to solar power, and also are apparently going to be pushing compact fluorescents in a major way to their customers.

The fact that these news stories show up on the same day, so soon after New Year's, is suspicious to me -- I smell a PR campaign. But if they back up the foofaraw with actual policy change, hey, let 'em hog some credit!
