Would 1100 square miles of solar collectors meet the annual electricity needs of the USA? (Approximately 4x1012 kWhr of electricity are needed in the USA each year.) Assume that all of the collectors are capable of tracking the sun and are in an area where the average annual solar irradiation is Gb=440 W/m2. Make appropriate assumptions as to conversion efficiencies.
