$this->bbcode_second_pass_quote('pstarr', 'v')t, folks will say that indeterminacy is the primary problem with solar, that the sun doesn't always shine or the wind blow. And that this requires the same amount (or more--you have to keep the big coal plants running all the time) of fossil-fuel electric power. Others point out that the power grid is the primary problem with electrical energy. We'd have to completely revamp it, add storage.
There is a simple workaround to this problem. Simply the grid. Disconnect the interconnects. Work when the sun shines, or when the wind blows. Needs only a little storage (make that hydrogen) The rest of the time you commune with nature, tinker, paint, discuss philosophy. Much like the rest of the world. We really don't have to compete and strive all the time. Freedom is great! But of course there are problems with all this: many jobs can not wait, a leaky second-floor pipe, a fire, etc.
A bigger problem is electric wall receptacles. Outlets, There are none where we drive and park.
Run a plug to the street, where city people park their cars. Rough estimate: 50 millions folks don't have garages, would need overnight charging of their EV (takes 8 hrs at 240 volts). Minimal cost to lay a new electric line from mains across the sidewalk
for each car:
--labor to cut holes through building, into the sidewalk, lays electric lines, install a charger and repair damage: $1,000
--cost of 240v charger: $1,500
--cost of manager (for accounts, payments etc like a public gas/diesel pump) and other electric components: $1,000
$3,500 * 50 million street parking chargers==$175 billion. Cost of just charger for suburban garages
50 million suburban cars, $75 billon. Now we have to wire up shopping centers. Oh. Ask me about interstate highways where there is no electricity.

You need to get a grip on the size of America and it's economy.
Last year Americans bought 17 million vehicles at an average price of $33,560 per car. That adds up to 570 billion dollars. Adding on $2500 to get each car it's own dedicated charger would not break the bank.
the USA changes it's working fleet over about a fifteen year period so we could put in all those chargers over the same time frame.
As to the interstate without electricity issue ,I'm glad you brought that up. Consider that a typical four lane interstate has a grass median thirty or more feet wide between the east/north bound and west /south bound lanes and another thirty feet or more of ditch line and slope on each side between the edge of the shoulder and the Right of way fence. Not all of that faces south of course but let us consider that on average you could install solar panels 25 feet wide on average clustered where they work the best. There are just under 48,000 miles of the Interstate system so a 25 ft wide strip would cover 145,000 acres of solar panels. I'll let you figure out how many EVs we could run off that.
