Hotels Using Alternative Energy

My bedtime reading of late has mainly consisted of research reports on alternative energy investment opportunities. All that got me thinking about which hotels use alternative energy. As always, the answer was just a quick Google search away:
1. A recent Interior Design article: "Green Upscale Hotels -- No Longer an Oxymoron"
2. Environmentally Friendly Hotels website
3. Alternative Energy blog

Am sure there's a lot more hotels out there. Could be another Little Cream Book in the making.
