"Five miles off the coast of Shanghai, the Chinese recently completed the country's first offshore wind farm.The project was completed before construction on the first American offshore wind farm has even begun.
..
In 2009, nearly $35 billion in private money flowed into Chinese renewable energy projects, including factories that make wind turbines and solar panels, according to the research firm Bloomberg New Energy Finance. The United States attracted under $19 billion.
"Within the past 18 months, China has become the undisputed global leader in attracting new investment dollars," Ethan Zindler, head of policy analysis at New Energy Finance, recently told a congressional committee."
Green cars such as the Chevy Volt are bound to be abject failures with their $40,000 price tags, so there's no reason to believe that the push for 'green jobs' in this country will be attainable without trillions of dollars in funny money from Uncle Ben's printing press.
If green jobs were profitable and made business sense, companies such as ADM, Weyerhauser, Caterpillar & tons of others would have jumped in two decades ago.
There is a electrician in my area that took a old TRECEL with 100,000 miles reworked it to be electric and drives it back and forth to work all week.It was made with a small budget with good old American ingenuity and is superior to the VOLT .Portsmouth Daily Times May 2 2009 edition you will have to pay archive fee.

That's wonderful - on its face.
What about some facts?
How FAR does he travel between recharges?
How BIG a battery does he haul?
What amount of watt-hours does he dissipate each trip?
Until you know those facts, the cheers may be premature.
Even the best EV advocates keep mum about their range on a full charge.

A fully depleted battery pack requires just under 21 kWhrs.
Your statement is not accurate, for watts and watt-hours are a measure of two different things.
Let me be clearer, for a 30mpg car going 12,000miles a year you average 400watts energy consumption. They have the same watt hrs.

In response to your really big numbers for the amount of solar you are looking at replacing the fleet in one year it doesn’t work that way. Cars last about 10 years on average. So 240 million/10 =24 million a year are replaced. If you take 1 million as new EVs with PV for power then you are looking at 1/240 or 0.416667% of the amount of production that you are talking about each year.
Tesla chose li ion laptop batteries, total cost over $20,000. Batteries requires hours to recharge, making public charging stations impossible for these vehicles.... Even if one put a lot of miles on the Tesla and managed to log 100,000 miles before the batteries needed replacing (almost impossible), battery cost per mile is still an exorbitant 20 cents. Drive a normal 50,000 miles and the cost per mile is 40 cents, or the equivalent of $12 a gallon gasoline, plus the electricity cost of around 2 cents per mile (assuming 10 cents per kWhr). I don’t think the public is screaming for $12 a gallon gasoline.
Can you see the problem NOW?
You can travel with $3 / gallon gasoline or the electrical equivalent at 4 times the cost... just for the BATTERY, alone.
My concept is to put PV on the roof of your house having a battery that recharges another battery (Li ion) or a switchable battery (lead acid) at home. Come home and plug it in overnight or switch the batteries. Good for 80~90% of most people’s driving. The Tesla is far from an economy car it a sports cars. With a reasonable energy consumption rate the battery pack size goes down as does the cost. Also with the subsidy the cost of purchasing the batteries will be spread around some. I will be doing a bit more research on this and will be getting back to you. But your $12 a gallon gas isn’t far from what they pay over the pond for gas.

The news paper article has all the info pay the fee. If i remember right he lived in Franklin Furnace Ohio and drove to Piketon Ohio everyday which is 40 miles away and back... 80 + total a day.The re-charging is done each day he returns & the plug is where the old gas tank was. I believe it a series of batteries that he recycled. For some reason i can no longer add links?
In physics, energy (from Greek ἐνέργεια - energeia, "activity, operation", from ἐνεργός - energos, "active, working") is a quantity that is often understood as the ability to perform work.
If you have 1 kW-Hr, and you draw 100 watts, you can do that for 10 hours.
If you draw 500 W, you can do that for 2 hours.
If you draw 1000 W, you can do that for 1 hour.

The figures were not to imply that conversion was to be done in one year, but that the actual cost of operation of an equivalent number of EV vehicles is not reasonable nor economical.
And as previously expressed, the inherent efficiency of rail based transportation trumps the EV car.
If you have X amount of energy, and you need to move Y number of people, and your choice is:
A) the automobile - which consumes 20 times as much energy as rail versus
B) the train, which is the logical choice?
(I omit the other beneficial points of rail - less surface area - scalability - efficiency - durability)
Don't think like the government, that can "burn money".
Think like a budget bound family, and you have to make a hard decision.
You have a fixed and finite budget of energy, and you need it to do work, moving passengers and cargo.
Storage material * Energy type * Energy per kilogram Gasoline (petrol) Chemical 47.2 megajoules Coal Chemical 24 megajoules Lithium battery Electrochemical 1.30 megajoules
It would take 36 times as much weight in lithium batteries to carry the equivalent amount of energy contained in gasoline.
The EV automobile is inherently a waste, needing tremendous weight for any long distance trip, or has very limited range.
The electric traction train does not carry batteries, tapping into power distribution, thus is inherently more efficient, as well as requiring less energy to overcome rolling resistance.
