The author is rebutting assertions that internet based computers account for roughly 10% of electrical power used in the US.  In addition to reviewing different sources of power consumption numbers he hooked up a digital power meter to his system.  In normal usage he figured it came to 150-170 watts of which 50 watts was for the CPU versus a rating of 400 watts according to the manufacturer and about 100 watts for the monitor.
