The most popular concept of sustainability revolves around energy use, and while I have no issues with energy as an issue, I think in business the idea goes further -- all the way to products and customers. I will leave the last couple of ideas for another time and concentrate on energy today. Actually, energy is a huge topic, and the only thing I want to focus on is the data center, not whatever you have in the garage. The data center might sound like a funny place to start, but it is both germane to CRM and a great place to kick this off.
