Help Americans 'Go Electric'
No matter what, energy consumption for automobiles and for everything else we already use is going to be electricity in the very near future ... from solar, wind, nuclear (?), geothermal, tidal current, etc. sources. In order to do this, the electric grid portion of the U.S. infrastructure is going to need major expansion. The sooner we do this, the sooner we will be able to "go electric". This work would be perfect for a WPA or CCC project to increase employment.
Trying to use more ethanol, hydrogen and LPG for automobiles and the like is a waste of time. We need heavy federal investment in battery research to expand the potential for hybrids and all-electric cars. Your grandchildren will not be able to drive cars running on hydrocarbon fuels. Peak oil has passed.
