A Google engineer has warned that if the performance per watt of today’s computers doesn’t improve, the electrical costs of running them could end up far greater than the initial hardware price tag.

That situation that wouldn’t bode well for Google, which relies on thousands of its own servers.

“If performance per watt is to remain constant over the next few years, power costs could easily overtake hardware costs, possibly by a large margin,” Luiz Andre Barroso, who previously designed processors for Digital Equipment Corp., said in a September paper published in the Association for Computing Machinery’s Queue. “The possibility of computer equipment power consumption spiraling out of control could have serious consequences for the overall affordability of computing, not to mention the overall health of the planet.”
