The survey <br />included electricity consumption from solar panels in the consumption/expenditures rate. The <br />extent of solar panel installation onsite within the development’s lifetime is unknown but is <br />expected to be similar to adoption across the Midwest. Annual household fuel consumption in the <br />Midwest for single-family detached homes was reported at 38.2 million Btu per year (11.1953 <br />MWh) for electricity and 86.6 million Btu per year (25.3799 MWh) for natural gas (52) (Table <br />30). <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
