General Energy Use, Strategies and Systems
Energy Strategies:
Passive solar design, evacuated tube solar hot water combined with on-demand electric hot water (as considered elsewhere, evacuated tube hot water system was a very poor choice and system was removed and replaced with a second PV system in Sept 2010), energy/water efficient appliances and technologies, and resident behavior of using what is needed and not wasting resources. By making our living space modest in size it is easy to conserve electricity because the radio in the kitchen is clearly heard in the living-dinning room, because reflective LED lighting of the kitchen and living-dinning room is accomplished with 80 watts, and because we only have two lamps in the living-dinning room area.
