You're joking right?
There is no way that the extra stress put on an alternator by the EWP will sap as much power as a mechanical pump.
The headlights and tailights draw more current than the EWP, and I don't know about you, but I don't feel the difference between driving with my lights on, and driving with them off.
Hell, I barely feel the difference between driving in the day with no lights and no stereo, and driving at night with all lights and stereo cranked.

Umm I have to pull this up. This is so far wrong its not funny. The laws of thermodynamics state that its impossible to transfer 100% of energy, some is always lost.
To turn the pumps impeller requires the same amount of energy regardless of its source. In the case of the mechanical pump its takes its energy directly from the engine.
In the case of the EWP the energy has to go from mechanical, back to electrical. The electric pump is powered by the alternator, the alternator gets its power from the mechanics of the car. This is several more conversions of energy, all of which result in lost energy, the EWP uses more energy from the engine than the standard water pump. Reviews stating this fact and finding the pump useless have been removed from magazines because DC threatened legal action.
The only use is if you were cruising along and didn't require the full power of the pump to give adequate cooling. This would mean the pump is not working as hard and might be using slightly less energy. The amount of power we are talking about is very small and wouldn't be noticed on any engine bigger than a Briggs & stratton.
