Does Turning Off Lights Really Save Money?

Turning off your lights saves a bit of energy, sure.

However, things like your water heater or air conditioner use tons of energy.

Far more than your light bulbs use.

That doesn’t mean that you can’t save money and energy by switching off the lights or the TV.

How much money do you save by turning off lights?

We’re typically gone for about 52 hours. Thus, if we turn off those same four 20 watt bulbs, we save 4,160 watt hours of energy. That’s 41.6 cents, which is getting to be worthwhile for two minutes of effort. This is assuming only lights, of course.

Is it cheaper to leave a light on or turn it on and off?

Fluorescent lights do take a small surge of power when turned on, but this is significantly smaller than the amount saved by turning them off. It used to be that starting them shortened their life, but again this is not significant. It’s always better to turn off modern lights if leaving for more than a minute.

How much does it cost to leave a light on for a month?

A “normal” incandescent bulb costs about 0.75cents per hour, and LEDs or CFLs cost only one-sixth of that – so leaving the lights on (either overnight or while you’re at work for the day, say both are about 8 hours) costs you roughly 6 cents for a normal light and a bit over 1 cent for modern bulbs.
