That's a general statement I'd agree with, but it's a losing battle. So many consumer products are rated by power that "I turn this 2000 W thing on for 1 hour, thus it consumes 2000 Wh of energy" is kind of convenient, if weird.

My real surprise and problem comes with Wh/x, where x is any unit of time. Why not cancel h/x for any dimensionless factor? This is what the grandparent is referring to.
