save energy

One easy way you can save energy (and money!) in your library is through your computer power management settings.  A typical desktop computer and LCD monitor can use over 200 watts a day. Laptops use less than 45 watts and Macs generally use  a lot less energy too. (more info)  By putting your computer to “sleep” you can cut back to 1-5 watts of energy.  Generally if you are going to be away for more than 20-30 minutes, set your computer and monitor to sleep/hibernate mode. This is especially good to do at night, weekends, or when you are away. Check with your IT folks to find out how they install updates to your computer, but many times they can either remotely turn on your computer, or set the updates to install once you computer is back on the network. (more info) The EPA has some information on computer power management settings for individual computers.  How to access these settings? In Windows XP go to start – control panels – power options:  set your monitor and your standby to 20 minutes. For Macs go to system preferences – energy saver. Also check that your peripherals are turned off – like the printer or copier -as well.  And buy Energy Star computers whenever possible – they use up to 60% less energy than non-energy star computers .  More computer energy saving tips.

Two common myths: no it doesn’t hurt your computer to turn it off and on frequently AND screensavers do nothing to save you energy.
