Turning off lights that aren’t being used is a simple and effective way to save energy. It does not require any equipment and the energy savings can be significant. AffordabilityTurning off lights is free. Breaking old lighting habits is the challenge. Cost savingsThe moment a light is turned off, it stops using energy, so your savings add up by the minute. If every household in B.C. turned off a 100-watt incandescent light for four hours each day, each bulb could save 3.3 cents a day. It would also save the province 227 GWh, which could power Whistler for 12 years. Health & comfortMany people find cutting electric light in favour of natural light to be calming. Natural light covers the full light spectrum, which gives it a comfortable colour temperature and tone that is difficult to mimic. Turning off unnecessary lights also reduces light that may shine onto your neighbour’s property and into bedroom windows, reducing privacy and hindering sleep. Environmental considerationsSince there is no equipment required, there are no environmental impacts from product manufacture, shipping or disposal. Get everyone in your household into the habit. Turning off unnecessary lights also reduces the light that may be cast up into the sky, preserving our view of the stars. |
Does it take more energy to turn a light back on than is saved by turning it off for a short period of time?
No. For most home lighting, there is no extra energy draw when a light is switched on. While fluorescent lamps do use a tiny bit more upon start-up, if the light is off for more than five seconds, you'll save energy.
Will turning lights on and off wear out the light bulbs faster?
While it is true that Compact Fluorescent Lamps (CFLs) can be sensitive to rapid on/off cycling in situations where only brief illumination is required, it is still better to turn lights off, even when it’s only for a few minutes. The energy savings will easily offset any reduction in lamp life.

B.C. star-gazers couldn’t be happier to hear that BC Hydro Power Smart has launched a campaign to fight light pollution in this province.
