Half?
The amount of power generated by an acre of turbines or solar panels in a year can be measured in kilowatts. The US consumes in terawatts.
We would most likely need to convert most of the open (read: farm) land west of the Mississipi to generate green energy on that scale.
In 2004, the total energy consumption of the US was 90.94 Quadrillion BTU’s or 3.2 TWh. This is from all energy sources not just electrical.
With 10% efficient Solar panels we can produce 0.5 KWh per day from 1 meter squared. So to provide for half the US energy needs from all sources never mind just electrical would require 2,179.45 acres
However the current record for solar photo-voltaic is now 42.8% efficiency not 10% with 65% just around the corner hence we should really only need 335.3 acres if we used the quantum dot 65% efficient solar panels.
