I agree that electric cars are a pipe dream. In addition to the insurmountable technical hurdles (i.e. laws of physics), there is the upcoming apocalypse nightmare which will end this particular pipe dream.
Good article on the less helpless approach:

A Solar Grand Plan
By 2050 solar power could end U.S. dependence on
foreign oil and slash greenhouse gas emissions
Ken Zweibel, James Mason and Vasilis Fthenakis
KEY CONCEPTS
■ A massive switch from coal, oil, natural gas and nuclear power plants to solar power plants could supply69 percent of the U.S.’s electricity and 35 percent of its total energy by 2050.
■ A vast area of photovoltaic cells would have to be erected in the Southwest. Excess daytime energy would be stored as compressed air in underground caverns to be tapped during nighttime hours.
■ Large solar concentrator power plants would be built as well.
■ A new direct-current power transmission backbone would deliver solar electricity across the country.
■ $420 billion in subsidies from 2011 to 2050 would be required to fund the infrastructure and make it cost-competitive.
Excerpts:
Although it is not possible to project with any exactitude 50 or more years into the future, as an exercise to demonstrate the full potential of solar energy we constructed a scenario for 2100. . . . Under these assumptions, U.S. energy demand could be fulfi lled with the following capacities: 2.9 terawatts (TW) of photovoltaic power going directly to the grid and another 7.5 TW dedicated to compressed-air storage; 2.3 TW of
concentrated solar power plants; and 1.3 TW of distributed photovoltaic installations. Supply would be rounded out with 1 TW of wind farms, 0.2 TW of geothermal power plants and 0.25 TW of biomass-based production for fuels. The model includes 0.5 TW of geothermal heat pumps for direct building heating and cooling. The solar systems would require 165,000 square miles of land, still less than the suitable available
area in the Southwest. In 2100 this renewable portfolio could generate 100 percent of all U.S. electricity and more than 90 percent of total U.S. energy.
The greatest obstacle to implementing a renewable U.S. energy system is not technology or money, however. It is the lack of public awareness that solar power is a practical alternative— and one that can fuel transportation as well. Forward-looking thinkers should try to inspire U.S. citizens, and their political and scientific leaders, about solar power’s incredible potential. Once Americans realize that potential, we believe the desire for energy self-sufficiency and the need to reduce carbon dioxide emissions will prompt them to adopt a national solar plan.
