How big of a solar farm would we need to power the United States?

    One solar farm produces about 1MW per every 8 acres of sun-land.  The US uses an estimated 1 million MWs.  That would mean that a solar farm would need to be approximately 8 million acres in order to power the whole country.

    As technology continues to advance, the field of solar power does as well.  While an average solar farm may produce 1MW per every 8 acres of sun-land, we now have solar farms which produce 1MW of energy per roughly 3.5 acres of sun-land.  This would mean that it would take approximately 3.5 million acres of sun-land to power the whole country.  Even these advanced solar panel systems have a long way to go before they are truly efficient.  Currently, these panels can only transfer a max of 30% of the solar power they receive.  If technology allows us to perfect solar power, we may be able to power the United States with a 1 million acre solar farm.
