Consider some of the traditional myths about equipment and energy use:

Myth: Leaving computers on helps them last longer.

Reality: Today’s computers do not suffer from being turned on and off thousands of time. In fact, turning computers off when they’re not being used lowers the amount of dust buildup inside, which helps them last longer while saving you money.

Myth: Energy costs are an insignificant part of total expenses.

Reality: Energy savings can always be used to fund materials, supplies and publications. In addition to your reduced utility bills, improved comfort is common after building upgrades.

Myth: Fluorescent light last longer if not turned on and off.

Reality: Switching fluorescent lights on and off does slightly shorten their life. However, any time lights are not needed for more than 10 minutes, you save more money by turning them off than by leaving them on.

Myth: I should replace old equipment with more efficient versions only as the old equipment breaks.

Reality: With some new technologies, such as T-8 fluorescent lights (20 to 60 percent savings) or light emitting diode (LED) exit signs (up to 90 percent), there’s just no reason to wait. You can start saving money on energy and maintenance cost right away.
