1. Save Energy - Turn Off Your Monitor!
As summer has apparently descended upon us already, it's a good time to
review your energy usage patterns. Computers and monitors (especially) do
use a fair amount of electricity, and it's good to try and conserve as much
as possible. This is especially important for those of you in locations
without air conditioning, since monitors put off a lot of waste heat!
Here's what I do, and what I strongly recommend:
- whenever you are away from your desk, turn off your monitor. Even for five minutes, this makes a difference.
- every night, shut down your computer completely.
- this also applies to public computers (kiosks and clusters). It may not be practical to turn the monitors off during the day (though you could stick little notes on them and try), but do shut them down and turn off the monitors at night! At LEAST turn off the monitors at night, please.
Some people may argue that turning off equipment this frequently will
cause wear and tear. It's possible it does, but I've never seen an
increased rate of demise on equipment treated this way - even a possible
reduced life span is probably beyond our replacement cycle. For instance,
the two monitors on my desktop, which are power-cycled several times a day,
are still going strong at almost 5 years.
Although the University generates it's own power at the cogen plant, it
sells excess to the state - the more we conserve, the better off everyone is.
So, stay cool and save energy!
