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.

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

But not electrical. 20W of power, but not electrical power
