When I'm designing a house to perform at a high level of efficiency, I like to simplify the energy equation to one mind-set: Convert the energy as inexpensively as possible, and then hold on to it as long as possible. The beauty of this approach is that as my energy-conservation efforts increase, my energy needs decrease. As the energy needs decrease, the conversion of that energy becomes more efficient, and so on.
