Do you genuinely believe that a company with such a huge investment in data centers is demonstrating a lack of focus by concerning themselves with energy?
IMO they would do better to offer hard-to-turn down deals to energy companies in return for guaranteed clean power. (it would be a hell of a thing to have on your power companies adverts)
Is it any stranger than designing and commissioning the manufacture of their own server hardware as to achieve a more efficient ratio of price/reliability for their specific use-case?
There's a lot of information to organize, and doing it efficiently at scale requires moving quite a bit farther down the stack.
Designing your own hardware also, incidentally, lets you control power consumption.
