EPA touts software to save energy


Computer users hoping to reduce their carbon footprint should learn how to use the “hibernate” function, which saves 57 times more electricity than screensavers, the Environmental Protection Administration (EPA) said at a press conference yesterday.

“The Directorate General of Budget, Accounting and Statistics said there are about 11 million personal computers in Taiwan. If everyone saved a little electricity on their computers, reductions in carbon emissions could be significant,” said Chu Yu-chi (朱雨其), director-general of the EPA’s department of environmental monitoring and information management.

Although computers put in hibernate mode consume only 2 watts per hour — a fraction of the energy used by computers with the screensaver on, which consume 115 watts per hour — Chu said about a third of computer users did not know such a function exists.

To help people learn about this function, the EPA has developed personal and business versions of a software called “Energy Saving Assistant,” which makes switching to hibernate mode automatic, Chu said.

“If every computer ran this software and was in hibernate mode for two hours a day, the nation could save 900 million units of electricity, or about the annual energy consumption of all of Taitung County,” he said.

In addition to switching computers to hibernate mode, the Energy Saving Assistant can also calculate a computer’s carbon footprint based on its duration of usage and display energy saving tips on screen.
