Do you pay more for non sinusoidal load?

Utility companies charge you by KWH electric usage. This applies to a linear, sinusoidal load.

If you have loads that draw non sinusoidal current (electronics, light dimmers), do you end up paying more, less, or equal to the actual energy used (integrating current x voltage over time)?

You end up paying less, but in your home you never notice the difference.
In industry they pay a power factor fee if their loads get too far out sync.

If you look at the specs for revenue meters, you will find that they measure real energy. Of course, there are limits in frequency response, sometimes rolled into a measurement called crest factor.
