Even an LED Draws Some Electricity

What is it about an LED that draws my attention? Well, for one thing, I expect complete darkness in my bedroom at night. Even an LED bothers me. So I hide my computer monitor's LED at night, as well as any other LEDs in the room.

So I notice them. So what? Well, to me they are a nuisance and a waste of electricity. Oh, I know there are other useful purposes to which they are put, and I have no complaint there. But I hate waste.

So how much electricity does a "useless" LED waste? Not much. But they do draw some electricity. Multiply that quantity by a gadzillion of the things and I suspect you'll come up with a surprising quantity. Now there is a mathematical equation for that waste...

P = K x Q

Pollution equals some constant times the number or quantity of LEDs of no value.

I know some years ago, a calculation was made that a"stand by" LED used about £10 in electricity a year. That might be £20 now, about $25 a year. You could have one on your CD player, the amp that powers it, your TV and many other electrical appliances. Some need to be there but I agree, as many as possible should be turned off. The LED doesn't bother me, though I think one sleeps better in total darkness.

Electricity does not come clean in this world. Solar is not prominently used. Nor is wind, steam, or any other such form.

And even when they are used, manufacturing the panels or turbines costs a lot in terms of materials and pollution.
