Abstract
The world could be powered by renewable energy: more energy from the sun hits the earth in one hour than all of the energy consumed on our planet in an entire year. Achieving a low-carbon economy is less technology dependent than it is dependent on new, well-designed energy law that broadly shifts private incentives towards efficient use of renewable energy using of “game-changing” technology such as Vehicle-to-Grid (V2G) motor vehicles that could shift the world to a low-carbon economy.

V2G vehicles integrate separate energy conversion systems: the electricity grid and light vehicle transportation fleet by storing electricity from the grid when it is not needed and returning it to the grid when it is needed. The total U.S. light vehicle fleet power capacity is about 39 times the power generation capacity of the U.S. electrical generation system. The grid could use power stored in idle V2G batteries whenever needed, yet each vehicle would be tapped only within the constraints of its drivers’ specific schedule and driving needs. 20,000,000 V2G cars (just 10% of the U.S. fleet) with an average peak power rating of only 50 Kw would have the combined power capacity equivalent to the entire U.S. Electric grid. This fleet would be the backup system for a fully renewable (e.g., solar and wind) energy generation system. The benefits of a V2G system could be enormous: dramatic reductions in CO2 emissions and the adverse health effects of air pollution from burning fossil fuels and a more robust electric grid. A renewable energy V2G system could replace fossil fuels in many regions of the world.
