Having worked with the TVA for many years, Alexander is well aware that the rather large Tennessee Valley region has an unused nighttime electricity capacity that is equal to the output of six or seven nuclear plants. He hopes that a lot of that energy can go to power transportation vehicles in the future and help offset imported oil. Although he believes this goal will take 15 to 20 years to achieve, he calculates that if half of our current fleet of cars and trucks had similar capabilities as his shiny black Prius, we could cut our oil imports by 4 to 5 million barrels a day - just about half. This, of course, would be great but we hope it happens a lot sooner than 2028.
