To replace Iowa's energy and fuels consumption with solar PV the estimates are as follows.

Iowa

626,791,122 megawatthours divided by 8,760 hours per year = 71,551 megawatts per hour averaged

x 6.43 (multplier)  = 460,072 mW p/hr minimum under ideal weather averaged - accessible with battery storage
x 6 acres = 2,760,432 acres
= 1 acre of solar PV in every 12.95 acres
= 49.42 acres of every sq mile of Iowa's land surface.  (excluding surface water acreage)

Iowa Energy Consumption Estimates 2014

Note; The replacement of gasoline combustion vehicles replaced by electric vehicles would have net reduction of energy effect of approximately 4,624 megawatts per hour.  (Example; Chevy Volt automobile with a rating of 100 miles per 38 kilowatt hours with an 80% recharge in 20 minutes.) This would have a net reduction of 40,514,035 mWh's annually and 32,599 installed megawatts on 195,594 acres. Currently Iowa consumes 1,494,982,814 gallons of gasoline annually which is equivalent to 54,716,371 megawatt hours. Electric vehicles similar to the Chevy Volt would only utilize about 14,202,336 megawatt hours for the same rated miles when compared to an automobile combustion ratio of 25 mpg for a total of 37,374,570,350 miles driven in Iowa. This would also have the affect of reducing the consumption of gasoline in terms of energy by 1,106,940,847 gallons of gasoline. This would also reduce the equivalent of 10,681,979 tons of carbon dioxide emissions. One gallon of U.S. automotive gasoline is equivalent to 36.6 kilowatt hours of electricity.

The above megawatt estimated requirements are for the replacement of energy and fuels consumed for electricity, heating and cooling, gasoline transportation fuels converted to its electric megawatt equivalent utilizing solar PV. We utilize Iowa's minimum annual ideal weather 30-year monthly-averaged useful daily hours of solar concentration.  These conversions would be Iowa's approximate energy demand equivalents in terms of energy, land, and cost.  For this conversion data set, one solar PV megawatt is equal to approximately six acres.  However, other solar PV installations are currently utilizing up to ten or more acres per installed megawatt. There are thermal solar installations utilizing 44 acres per installed megawatt.  ("resulting in a land-to-power ratio of 44 acres (180,000 m  ) per 1 megawatt.") ref; Thermal Power Towers - "Power Tower Designs"  wikipedia

This installed PV solar energy estimate does not include land cost, taxes, additional infrastructure, or any other cost.  And, additional at-load losses when the solar collection minimum service hours can not be met because of less than ideal weather, nor the cost of future growth.
