What does the US look like in 2020, 2050 or 2100? Can California and the US meet its goals for reducing GHG and ending petroleum dependence? Can we reach those goals with one dominant vehicle technology or fuel source? How much does it cost to reach the goals? Will new technology be affordable? Is one fuel clearly better than another?

A number of academic, government, and industry organizations have studied the potential futures in transportation. They use research, modeling, testing and demonstration to predict what needs to start today to reach goals that are decades away. On these pages, you’ll find links to reports and studies that are peer reviewed and well vetted.

No one can predict the future, though. And it’s hard to tell what consumers will ultimately accept. Will the adoption of new automotive technology follow a curve similar to cell phones, or the hybrid vehicle curve, or Twitter curve? As more vehicles of all types enter the marketplace, you’ll see studies and reports about consumer acceptance.
