However, before you even think about that, energy conservation is the best strategy that offers, by far, the greatest cost savings and positive environmental impact with the lightest investment. Conservation will ensure that you get the most for your money when purchasing a clean energy system. One cannot always accomodate for this entire checklist, but it is the best idea to try. We want a house to be highly energy efficient before installing a solar energy power system.
