Keep in mind that’s not accounting for energy consumed from neurons burning oxygen, which accounts for 20% of a human body’s consumption. https://www.ncbi.nlm.nih.gov/books/NBK28194/

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.
