Assuming 2000 calories/day, a human averages 97 Watts/hour.

Ke Jie is currently 19, so he has used an estimate of 670kWH for both his training set and playing his games.

Getting a machine to win that consumes less than 97W/H would be hard.

Taking a new machine and loading training data on it and having it win would be far less than 670kWH

97W, not 97W/h.

> Watts/hour

Watts is already "per hour", mind. Or per second to be precise.

Why is electricity then measured in kW/h?

In my understanding, power (instantaneous) is measured in W, but consumption needs to be integrated over time, thus the per hour part.

It's not kW/h, it's kWh https://en.wikipedia.org/wiki/Kilowatt_hour

[TeMPOraL]

Which is kW * h, i.e. kilowatt times hours, like man-hours are number of men multiplied by time.

[Sharlin]

kW/h would be a unit of the derivative of power, measuring the rate at which power consumption changes.
