In particular, the AEO2007 projects
...increased consumption of biofuels (both ethanol and biodiesel), growth in coal-to-liquids (CTL) capacity and production, growing demand for unconventional transportation technologies (such as flexfuel, hybrid, and diesel vehicles), growth in nuclear power capacity and generation, and accelerated improvements in energy efficiency throughout the economy. Despite the rapid growth projected for biofuels and other nonhydroelectric renewable energy sources and the expectation that orders will be placed for new nuclear power plants for the first time in more than 25 years, oil, coal, and natural gas still are projected to provide roughly the same 86-percent share of the total U.S. primary energy supply in 2030 that they did in 2005 (assuming no changes in existing laws and regulations).This should be a wake up call (it was for me). Our over-dependence on fossil fuels may continue unabated for the next 25 years unless policymakers (and the voters) decide otherwise and put in place policies that say "time to do things differently: cleaner, more efficient, more secure." Continuing on this business-as-usual route is going to keep us on the business-as-usual addiction to fossil fuels and worsen the effects of global warming.
