It was estimated back when incandescent was standard.

Keep in mind that’s not accounting for energy consumed from neurons burning oxygen, which accounts for 20% of a human body’s consumption.

20% of your bodies energy is about 20 Watts.

Normal-weight humans burn about 2200 kilocalories a day, which is about 9.2 megajoules. There are 8640 seconds in a day, so that works out to roughly 100 joules per second, or 100 Watt. 20% of that is 20 Watts for the brain.

That's rest consumtion tho.

Well done. So even added to the electrical consumption it’s less than an incandescent bulb. Incredible.
