@rgbrenner post below with US census data confirms US Population rise till 2050. In my above post my calculation of required increase on US electric grid base load is based on 'one CAR' per household which I just realized as wrong calculation. Based on the info. below US avg. Household size is 2.6 , then number of CARS per household is at least 2. so when 25% of cars are Electric Cars, you need 25% increase in utility Electric base load, and for 80% EV cars you need 80% increase. That is huge!!!!!!!!!!!! @toomuchtodo , anyway It is good discussion. I am glad I digged all this info in order to reply. Now it is crystal clear in head what are the US electric grid increasing load needs for the next 20 years. Hope our Policy makers and Politicians do this simple MATH and prepare with more SOLAR future accordingly .. https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=total%20number%20of%20households%20in%20usa https://www.google.com/webhp?sourceid=chrome-instant&ion=1&e... # of Households: 133,957,180 # of people in a household: 2.6
