There are a lot of myths out there about energy efficiency. For instance, it is a myth that turning your computer off-and-on takes more energy than just leaving it on or in “sleep” mode; and the Patrick administration just announced it is taking advantage of this ridiculously easy way for the state to save some serious cash.
Boston (WBZ) – The Patrick Administration says it can save $2 million and 12 million kilowatts a year just by turning off computers at executive branch agencies. The administration on Friday announced a new policy of shutting down the computers or switching them to energy saving “sleep mode” when they aren’t being used. Aside from the energy and cost savings, the administration estimates the policy will reduce 5,051 tons of carbon emissions — roughly equivalent to driving 925 cars for a year or providing electricity to 669 homes for one year.
So how about a few other myths along these same lines:
- Myth #1 – Turning off lights uses more energy. Turning off lights, even for short periods of time, really saves energy, with little impact on the lifespan of the bulb.
- Myth #2 – Turning off car uses more energy. Idling a modern car always wastes more energy than turning it off and then on again (even for short periods of time).
- Myth #3 – Turning down thermostat uses more energy. It is good to turn down the thermostat while you’re away from the house for the day. If you are out for a good stretch of time (say 8 hours or so), this temperature “set-back” will save more energy than it will take to bring your home back to the desired temperature.
