Here is perhaps the best sign that computing has really gone mainstream: Starting today, servers can be equipped with the same kind of yellow Energy Star tags as a stove, microwave, or refrigerator.

From a business point of view, the power and hardware savings from code optimization usually don't compare well to the same effort spent on building new services. Power is cheap, today's servers are losing value, and tomorrow's servers will be faster.
