Buoyed by the success of electric vehicles, other transportation sectors including planes, boats and trains are following their own paths toward petroleum replacements in an attempt to lower emissions.

What’s at Stake?
Transportation accounts for much of the world’s CO2 emissions due to the use of petroleum-based fuels. Reducing those emissions is among the keys to slowing climate change. One solution is substituting a carbon-neutral fuel for gasoline, diesel and their variations. The technology for doing so is on the way, but it will take tremendous amounts of renewable and inexpensive electricity to create these carbon-neutral fuels.
