A university’s campus has 20,000 computers with cathode-ray tube monitors that are powered up even when the computer is not being used. This type of monitor is relatively inefficient, and it draws more power than a flat panel display.

(a) If each cathode-ray tube monitor draws 0.1 kW of power over the course of a year, how much energy has been consumed? Express your answer in the conventional units of for electricity.

(b) At the cost of how much does it cost the university each year to keep these monitors powered up?

(c) On average, a computer monitor that has the automatic sleep feature enabled will consume 72% less energy than one that is continually powered. What is the cost savings associated with enabling this feature on all of the university’s computers?
