- Here is an item extracted from the Washington Post which may interest you.
-
- The EPA is trying to promote energy-efficient personal computers.
- A single PC doesn't use much electricity. You can keep
- your home computer turned on around the clock for a month and barely notice the
- difference when the electric bill comes around. But with personal computers now
- humming away in tens of millions of offices and tens of millions of homes, the
- EPA started counting kilowatts and came up with a striking conclusion.
- The agency released figures earlier this year suggesting that personal
- computers account for 5 percent of the total commercial electricity consumption
- in the United States; with computer use spreading like crazy, the figure was
- projected to rise to 10 percent by the end of the decade.
- When you start talking about 5 percent or 10 percent of all U.S.
- electricity, you're counting an awful lot of kilowatts. So the EPA, working with
- computer, chip and software makers, has promoted "green computing" as a way to
- save energy and reduce air pollution at home.
- The EPA's analysis is based on the thesis - which sounds right - that most
- people leave their desktop PCs turned on all the time. But those machines are
- actually used only about 20 percent to 30 percent of the time. So if the
- computer could be designed to switch automatically to a low-power "sleep" mode
- when not in use, there could be significant savings in power consumption.
