Fuels produced using plant-based materials can offer a promising way to reduce the carbon emitted by road vehicles.
That’s because their plant feedstocks absorb carbon dioxide from the air, bringing them far closer to a carbon-neutral footprint than any fuel refined from crude oil.
But for diesel-powered vehicles, the term “biodiesel” is used loosely and imprecisely–and often covers anything from plant-derived fuels to burning used deep-frier grease in your converted old Mercedes.

With a planned population of 50,000 residents, Masdar City in Abu Dhabi will be the world’s first carbon-neutral, zero-waste city completely powered by renewable energy. As it nears completion of the first leg of development, the futuristic project is now adding another first — a new smart appliance pilot program that will measure and transmit real time power consumption over a two-year period. Involving some of the city’s first residents, the program will test how GE’s smart appliances, also known as demand response enabled appliances, and GE’s Home Energy Manager technology can plug into a smart grid to lower power demand in the home and across the city.
