@rgbrenner post below with US census data confirms US Population rise till 2050.<p>In my above post my calculation of required increase on US electric grid base load is based on &#x27;one CAR&#x27; per household which I just realized as wrong calculation.<p>Based on the info. below US avg. Household size is 2.6 , then number of CARS per household is at least 2.<p>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!!!!!!!!!!!!<p>@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.<p>Hope our Policy makers and Politicians do this simple MATH and prepare with more SOLAR future accordingly ..<p><a href="https:&#x2F;&#x2F;www.google.com&#x2F;webhp?sourceid=chrome-instant&amp;ion=1&amp;espv=2&amp;ie=UTF-8#q=total%20number%20of%20households%20in%20usa" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;webhp?sourceid=chrome-instant&amp;ion=1&amp;e...</a><p># of Households: 133,957,180<p># of people in a household: 2.6
