* it loses far less power over long electrical lines{{fact}}<!-- No, it won't. For Canada-sized lines, it might even lose more. The real reason is the availability of transformers for voltage step-up, and _this_ reduces losses. -->
 
* it is the most used system as a result
 
* it is the most used system as a result
 
* given that it's the standard system used in [http://en.wikipedia.org/wiki/Mains_power_around_the_world electrical mains power], it is the most practical system to adopt in the domestic electricity system as well.{{fact}} Although power can be generated completely off-grid, there is an advantage to transfering/sell off surplus electricity  to the national power companies; ie via [[net metering]]. Adopting AC power as the standard, allows the use of less equipment (ie [[power inverter]]), also there is no 10% power loss due to the use of this inverter.

* Power lines can be thinner to than comparable DC lines. In practice, ie 12 gauge AC wire can be used, while 10 gauge DC wire would be required. When extrapolating the wiring problem into practice ie in a lightining situation, we see that on AC, 8 lights can be powered, and only 3 on DC<ref>Earthship volume II by Michael Reynolds</ref>
