Reducing climate change by saving energy is an important effort we should all join, and that's why we're very glad to see the innovative thinking going into a variety of solutions. One idea, suggested by the site called "Blackle" (which is not related to Google, by the way, though the site does use our custom search engine), is to reduce energy used by monitors by providing search with a black background. We applaud the spirit of the idea, but our own analysis as well as that of others shows that making the Google homepage black will not reduce energy consumption. To the contrary, on flat-panel monitors (already estimated to be 75% of the market), displaying black may actually increase energy usage. Detailed results from a new study confirm this.
As computers become a bigger part of more people's lives, they will consume an increasing amount of energy, which is why we've invested so much in making our data centers efficient and we've joined with others to launch Climate Savers Computing, which has a goal of reducing total power consumption by more than 50% for all computers by 2010.
There are some things you can do now to reduce the energy used by your computer, such as:
- turn on the power management features. Virtually all computers today have the ability to switch into low-power modes automatically when they're idle; very few computers have this capability enabled! Here's how to do it on computers running Windows XP.
- turn off your monitor and computer when you're not using them
- turn down the brightness on your monitor
- make sure your next computer meets the efficiency standards of Climate Savers Computing (an efficient computer uses up to 50% less energy than a conventional one)
- to find the most efficient PCs available today, look for the words "EnergyStar 4.0 compliant."
