 Most biomass fuels (biofuels) are used for heating and power. Some, however, can be used as fuel for cars and trucks. You may have already heard of ethanol, a biofuel made from plants such as corn or sugarcane. Other plants, like soybeans, can be used to make biodiesel, another biofuel. These fuels can be used pure or blended with standard automotive fuels to lower carbon dioxide emissions. In Brazil, millions of cars already run on ethanol. Someday soon the same might be true for other countries around the world. Shell is one of the world’s leaders in developing new biofuels technology. As the process of making ethanol and other biofuels becomes more efficient, fast-growing crops could one day be grown specifically for making fuel. And waste from farms or forestry operations could be used to make electricity, instead of being thrown in landfills. That gives a whole new meaning to the term "power plants!"
