"30kW per day" makes no sense. It's like saying "100km/h per day". W is a unit of power, Wh is a unit of energy.
It's unintuitive because a guy named Watt decided "Joule per second" is Watt, so the intuitive units Joule and Joule per second got turned on their head to W times hour and Watt. This is opposite to usual intuition of distance and speed for example, km and km/h. If I redefined the km/h to a "tick", then a km would become "tick times hour".
If you want a "better than nothing" but imperfect analogy, Wh is how much water you have in a bottle, and W is how quickly you can get the water out.
The naming of the unit is posthumous
And yet all utilities of the world decided to use kWh as the thing to measure. Also basically all smart measurement devices settled on this being the default to show. Exactly in the way he used it here, kw per day, kw per week, kw per month, kw per year.
This discussion seems super silly, considering he's just using the measurement that the industry adopted decades ago...
Are y'all just coming out of a time travel device from the 70s or something?
