Google really are a contradiction. I guess it’s what happens when you become a large organisation with megalomaniacs at the top, ex-Microsoft middle-management psychopaths, and a lot of crazy engineers trying to solve big problems. From Coding Horror:
Google wants to extend that same efficiency outside their datacenter to your home PC. The three page Google whitepaper High-efficiency power supplies for home computers and servers (pdf) outlines how and why:
At Google, we run many computers in our data centers to serve your queries, so energy conservation and efficiency are important to us. For several years we’ve been developing more efficient power supplies to eliminate waste from power supplies. Instead of the typical efficiencies of 60-70%, our servers’ power supplies now run at 90% efficiency or better, cutting down the energy losses by a factor of four.
We believe this energy-saving power supply technology can be applied to home computers, too. So we’ve been working with Intel and other partners to propose a new power supply standard. The opportunity for savings is immense — we estimate that if deployed in 100 million PCs running for an average of eight hours per day, this new standard would save 40 billion kilowatt-hours over three years, or more than $5 billion at California’s energy rates.
