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.

District of Columbia Energy Profile Analysis

Solar PV to replace all of the District of Columbia spent fuels: 373 sq miles
= 54.14 square miles of solar PV for every 1 square mile of the District of Columbia land surface (excluding surface water)

As can be seen the net result is impossible.

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

49,034,159 megawatthours divided by 8,760 hours per year = 5,597 megawatts per hour averaged

x 7.12 (multplier) = 39,850 mW p/hr minimum under ideal weather averaged - accessible with battery storage
x 6 acres = 239,100 acres
= 1 acre of solar PV in every .16 acres (6.08 times more land than Washington DC has)
= 54.14 sq miles for every sq mile of Washington DC's land surface. (excluding surface water acreage)

Note; The replacement of gasoline combustion vehicles replaced by electric vehicles would have net reduction of energy effect of approximately 248 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 2,495,508 mWh's annually and 1,607 installed megawatts on 9,642 acres. Currently the District of Columbia consumes 68,183,278 gallons of gasoline annually which is equivalent to 2,495,508 megawatt hours. Electric vehicles similar to the Chevy Volt would only utilize about 874,313 megawatt hours for the same rated miles when compared to an automobile combustion ratio of 25 mpg for a total of the 2,302,129,075 miles driven in the District of Columbia. This would also have the affect of reducing the consumption of gasoline in terms of energy by 68,183,278 gallons of gasoline. This would also reduce the equivalent of 657,968 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 the District of Columbia's minimum annual ideal weather 30-year monthly-averaged useful daily hours of solar concentration. These conversions would be the District of Columbia'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.
