Our thought process is to spend money on energy efficient appliances and lighting rather than on RE systems that will give us minimal return on investment. This is not to say that I won't attempt RE power in the future. The house will be wired using electrical wiring guidelines for residential homes. This means that each circuit will allow for incandescent lighting and power consumptive appliances even though we plan on using compact fluorescent lighting and low wattage appliances. In doing so, all of the electrical circuits will be well within the load limitations.
Current plans are to use conduit throughout the house.
This is overkill, but especially when running electrical cables through cordwood walls, I feel it's important to future proof the design. Trying to replace wire once a cordwood wall is up requires a sledge hammer. And always, check out what is code for your area first. Our county will allow NM cable, but conduit will be used.
