Texas would not be the only place struggling to meet demand. If everyone is fueling their cars with electricity, demand is going to be high in all cities.&lt;p&gt;Without fossil fuels we need to find new sources for power. It&amp;#x27;s not good enough to say &amp;#x27;electricity&amp;#x27;, how do you generate it at a capacity that fills in for the 20.5 million barrels of oil consumed a day in the USA?&lt;p&gt;The numbers are interesting. There is 17500 kw&amp;#x2F;h or 1.7 mw&amp;#x2F;h in a barrel of oil. Using 20.5m barrels a day, that&amp;#x27;s 34.85 million mw&amp;#x2F;h a day. The US currently generates around 10 million mw&amp;#x2F;h of electricity a day[1].&lt;p&gt;Granted, a fraction of a barrel of oil is used for gasoline, but you can see that the grid will need a sizeable upgrade if it is to fill in for our dependency on oil.&lt;p&gt;Please forgive me if I have some of this wrong!&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;List_of_countries_by_electricity_consumption&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;List_of_countries_by_electrici...&lt;/a&gt;</text><parent_chain><item><author>zaroth</author><text>That&amp;#x27;s over ~$750 for the power stored in a single Tesla battery pack.

That would avoid the need for expensive and complex grid connection equipment in individual EVs. Even if the reused batteries are down to 60% capacity, stacking a bunch of them could deliver enough power for demand spikes.</text><parent_chain><item><author>zaroth</author><text>That&amp;#x27;s over ~$750 for the power stored in a single Tesla battery pack.
