Apple has reached a cool milestone…their data centers, historically facilities of massive power consumption, are now powered by 100% renewable energy! It has accomplished this by building large solar arrays, building a fuel cell power plant, and also purchasing renewable energy credits from its energy suppliers. It’s not just good for the environment…the more a company can rely on already-installed solar panels, the more predicable (and lower) operating costs become over the life of those panels. It just makes good business sense, if you can afford the initial investment.
