Alternative Fuel and Propulsion Technology
An engine, fueled by petrol or diesel, drives the highest numbers of automobiles. Both fuels are known to cause air pollution and are also blamed for contributing to climate change and global warming.
In 2011 there were more than one billion vehicles in usage in the world.
- About 34 million flexible-fuel vehicles as of October 2013, managed by Brazil with over 23 million units, the United States with almost 10 million flex-fuel cars and light duty trucks, Canada 600,000, and Sweden led by 229,400 units.
