Brazil has the most advanced biofuels program in the world, by far.

Ethanol alone accounts for roughly 1/5 of all energy in Brazil, with almost 50% of light-vehicle fuels being renewable.

For heavy vehicles, biodiesel is gaining in. Ethanol started in the 70s, the biodiesel program is much more recent (10-15% mixture in regular diesel).

It's not just electricity here, we're doing serious work on the fuel front.
