I don&amp;#x27;t.  You rarely need to charge an electric car from empty.&lt;p&gt;I agree that solar is significantly less attractive in high-latitude, cloudy locations, though.  All of those panels that Germany installed would have been much more useful in Arizona.&lt;p&gt;Hydrogen, of course, is a boondoggle:  it&amp;#x27;s primarily a fossil fuel, needs a whole new distribution system, is less efficient than pure electric, and requires very expensive vehicles.</text><parent_chain><item><author>sandworm101</author><text>&amp;gt;&amp;gt; they would most likely even out 24-hour usage patterns rather than overstressing the grid.&lt;p&gt;Take a look at exactly how much power goes into an electric vehicle.  I once worked out how many solar panels one would need to charge a tesla once per day in my local.  The math pointed to something like a solid acre of land dedicated to sustaining a single car.  (not an acre of panels, at my latitude you need proportionally more land on which to mount panels).  A shift to all-electric transport would produce a demand for which LEDs could never compensate.  Only the very wealthy would ever own enough land to actually self-sustain through renewables.  Cities will need power grids for a long while.&lt;p&gt;Take electric transport out of the equation and things start looking much better.  Hydrogen-powered vehicles would imho at least allow the possibility of &amp;quot;de-electrification&amp;quot; in north america.</text></item><item><author>flyinghamster</author><text>The first thing I noticed about the article was the complete non-mention of energy efficiency.
