In fact electric cars today still only go as far as electric cars did 100 years ago. Without some kind of breakthrough in electric energy production or storage it will stay that way.
Coal and oil are still the most plentiful and easily stored forms of energy and overall considering those things, the cheapest. Moving to something else will happen when other forms of energy are available at the prices and convenience of coal and oil.
If we were to pay for the oil hegemony motivated wars in the middle east.. add in all the bribe money we pay Pakistan, Afghnistan, Egypt, Israel. ..direct oil (welfare)subsidies and oil would cost over 300 dollars a barrel...
At present photoelectric conversion efficiency and under typical seasonal cycles and weather, a solar panel one square meter in area produces about .5 kilowatt-hours of energy per day. Since a barrel of oil contains 1700 kilowatt-hours of energy, it would take 3400 square meters of solar panels to produce the equivalent energy of a barrel of oil per day.
Currently, Iraqi oil fields produce 2.2 million barrels a day. To match this output with sunlight, we would need 7500 square kilometers of solar panels (= 2.2 million barrels x 3400 sq. meters/barrel). At a market price of $600 per square meter, the total cost of replacing Iraqi oil-produced energy with sunlight would be $4.5 trillion – approximately $410 million a day when amortized over a thirty year hardware lifetime. The equivalent cost in terms of oil-derived energy would then be $190 per barrel.
Expensive, yes, but the official cost of occupying Iraq is $400 million a day, which means that we are already paying a "war subsidy" of $180 a barrel for Iraqi oil!
Currently we are deficit-spending to fund our bloated military and all the war costs and oil hegemony motivated "foriegn aid".
Cut out all the oil related spending like subsidies, war, military related.. and Solar energy will be easily competitve with fossil fuels... add to that the benefits to our national security and new industry potential( solar panels have to be manufactured and replaced) and solar energy in the U.S is a no-brainer... if your intersted in the wellbeing of the U.S as a whole.. and not beholden to the Fossil Fuel industry and the Military Industrial Complex
Instead of Deficit spending to fund all these collateral costs...and the costs were added to all our energy consumption as a tax... Resdidential Solar Energy would take off like a proverbial rocket.
