Solar PV to replace all of South Dakota's spent fuels: 983 sq miles
= 1 square mile of solar PV in every 77.09 square miles of South Dakota's land surface (excluding surface water)
Note; The replacement of gasoline combustion vehicles replaced by electric vehicles would have net reduction of energy effect of approximately 1,242 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 10,886,836 mWh's annually and 8,271 installed megawatts on 49,626 acres. Currently South Dakota consumes 403,573,278 gallons of gasoline annually which is equivalent to 14,770,782 megawatt hours. Electric vehicles similar to the Chevy Volt would only utilize about 3,833,946 megawatt hours for the same rated miles when compared to an automobile combustion ratio of 25 mpg for a total of 10,089,331,950 miles driven in South Dakota. This would also have the affect of reducing the consumption of gasoline in terms of energy by 297,454,535 gallons of gasoline. This would also reduce the equivalent of 2,870,436 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 South Dakota's minimum annual ideal weather 30-year monthly-averaged useful daily hours of solar concentration. These conversions would be South Dakota'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

174,670,359 megawatthours divided by 8,760 hours per year = 19,939 megawatts per hour averaged
x 5.26 (multplier) = 104,879 mW p/hr minimum under ideal weather averaged - accessible with battery storage
x 6 acres = 629,274 acres
= 1 acre of solar PV in every 77.09 acres
= 8.30 acres of every sq mile of South Dakota's land surface. (excluding surface water acreage)
