$5/W sounds hideously expensive.  It's nearer $2.6/W installed here in the UK!

But as far as your analysis goes, you haven't factored in the money that 
hundreds of companies that supply the armed services have made out of the war.  
That means jobs which keeps the politicians in power and everyone's a winner... 
except for all those who are killed, wounded, displaced etc etc.

Of course, you could still have lots of jobs but in the renewable energy sector 
instead but try telling that to your average politician or gargantuan ICE SUV 
driver!

Peter,
You are very generous with install cost of $5 per Watt and I think that
cost level is old. Today's solar panels are all under $1 per Watt with
few exceptions and installation typically doubles or triples that with
the man-hours and the inverter  installation material costs. What I
have heard is closer to $2 per installed Watt for standard residential
systems.

You flip twice (cancelling the error) between 7.2 and 7,200

Most EVs are better than 3 miles per kWh, a few are less.
It is a safe (relatively low) number since the majority of EVs get
closer to 4 miles/kWh.

Just some quick feedback. Good thought-provoking issue.

Here's a parallel way to look at it, except with wind generation:

According to the US DOE, in table 1:
http://www.eia.gov/forecasts/capitalcost/pdf/updated_capcost.pdf

the cost to build a wind farm is $2213/kW to build + $40/kW-yr to 
operate.  Add to that pumped storage of the same capacity: $5288/kW to 
build + $14.13/kW-yr to operate and you would have about $7500/kW to 
build + about $54/kW-yr to operate.

The US used about 1000MW peak during summer of 2012 - see table 4.2.B in

To build out with 100% wind, that would cost:
wind generation = $7500/kW to build or $7500k / MW to build
1000MW would cost 1000 * $7500k = $7,500,000k = $7,500M = $7.5B

That's about 0.4% of the $1.7T.

In other words, we could completely replace our existing power 
generation with zero-carbon production and have plenty of money left 
over for operations, hyper-quick chargers everywhere, and just about 
every other government expense conceivable!


By the way, you can do the math, but wind is substantially cheaper than 
building nukes if you include the operating costs of nukes.

[corrected! And results are 10 times better!]

Remember this solar investment is the upfront cost.  From then on, it has
paid for free transportation energy for emissions free EV's  forever...

 Lets try this

 $1.7T divided by $3.30/Watt cost of solar = 500 BWatts of  capacity.

 In Maryland each kW of solar capacity delivers about 1200  kWh of energy
per  year.

 So the result is $1.7M generates 600 B kWh per year  forever.
 An average EV drives say 10k mi/yr at 3miles per kWh or  3,000 kWh per car
(corrected)
 But remember this investment buys continuous FREE power from  the sun
FOREVER (25-to-50 yrs anyway)
 So the $1.7T investment would power 200 million EV's  FOREVER and, we'd be
70% transportation emission free by now.

BUT we didn’t.  BUT,  we ALSO spend over $1B per DAY for foreign oil,  that
is another 40  million EVs PER YEAR that can be added to the list of
continuously powered
 (forever) emission free transportation from the sun.

If we just started NOW investing the $1B per day we spend on foreign oil and
spent it on solar for EV's we'd get to the same drive-forever on solar for
70% of our transportation in 5 y ears.

 Why aren't we doing this?

Big mistake! (I knew something was wrong).

US peak in 2012 was 1,000,000MW (not 1000MW).  So, total build-out cost 
would be $7.5T.   Ok, that exceeds the challenge.


How about just looking at coal?

US peak in 2012 (same table) was about 300,000MW.  The build-out to 
replace coal would be:

300,000MW * ($7,500M/1000MW) = 300 * $7,500M = $2,250,000M = $2.25T.

That's not so far off the challenge.   So we could replace 75% of US 
coal power plants!  Who-hoo!  That would pretty much eliminate the 
pundits' claim that EVs simply displace the CO2 output.

This produces a result of 2.04 billion miles.

How does this equate to miles driven per day using an equivalent 
gasoline powered sedan?


Assume for discussion purposes:

1)The USA uses 20 million Barrels of Oil Per Day (BOPD).In recent 
years, this figure has decreased to about 18 million BOPD.


2)Each barrel of oil can be refined to produce 18 gallons of 
gasoline.This is close to the actual production figure.


To derive the amount of average car miles that can be driven in a day 
using gasoline, the above factors were multiplied together like so:


20 million BOPD * 18 gallons of gasoline/BOPD * 20 Miles/Gallon = 7.2 
billion miles/day


We drive roughly 7.200 billion miles per day.

21 million BOPD over 7.2 billion miles
