&gt;almost 80% of vehicles could move over to the electric grid with existing base load generation.<p>hmm... I am little surprised with that DOE math.<p>Avarage US Houldhold use 900 KWh per month as per link below.
Electric car takes a total of 425 KWh to re-charge per month ( based on 1000 miles driven per month, see my own Nissan LEAF calc. below)<p>So by 2025-30 when USA Electric vehicles are 25% (of Total vehicles), USA grid needs 12.5% increase in base load.<p>When 80% are EV, then US need 40% increase in base load.<p>----
How much electricity does an American home use? <a href="https:&#x2F;&#x2F;www.eia.gov&#x2F;tools&#x2F;faqs&#x2F;faq.cfm?id=97&amp;t=3" rel="nofollow">https:&#x2F;&#x2F;www.eia.gov&#x2F;tools&#x2F;faqs&#x2F;faq.cfm?id=97&amp;t=3</a><p>In 2014, the average annual electricity consumption for a U.S. residential utility customer was 10,932 kilowatthours (kWh), an average of 911 kWh per month.
----<p>Here is my household Electricity consumption monthly breakdown in Kwh (from my Utility PG&amp;E monthly bill)
- I drive Nissan LEAF 100% Electric car about 1000 miles per month ( typical US avg.)<p>Nissan LEAF re-charge* : 425 Kwh ( monthly total )<p>other household electrify: 400 Kwh ( I am low on household Kwh use, that is why I took US Avg 900 Kwh in above Calc.)<p>* The fact that I re-charge Nissan LEAF only After 11 PM to get Off Peak rate of 11 cents Kwh, my Utility Bill show &quot;Off Peak Kwh used in a month&quot; , that is how I know exact KWh used for my Nissan LEAF re-charging.
