The IT equipment comprising the Internet in the USA uses about $6 billion of electricity every year. Much of this electricity use is wasted on idle, but fully powered-up, desktop PCs and network links. We show how to recover a large portion of the wasted electricity with improved power management methods that are focused on network issues.

This chapter presents some results of an econometric analysis (developed in Patrick and Wolak 2001b) of customer-level demands for electricity of large and medium-sized industrial and commercial customers purchasing electricity under half-hourly spot prices and demand charges coincident with system peaks in the England and Wales (E&W) electricity market. These estimates can be used to forecast ...
