On August 10, 1893, mechanical engineer Rudolf Diesel successfully tested the engine that would eventually bear his name. The test took place in Ausburg, Germany. Unlike engines that run on fossil fuels, diesel engines are able to run on biodiesel fuel (fuel made from plant or animal fats).
Biofuels are in many ways preferable to fossil fuels because their supply is easier to replenish. Biodiesel is considered a renewable energy source. The emissions associated with biodiesel are also less harmful to the atmosphere. Honoring Rudolf Diesel's test, International Biodiesel Day is celebrated each year on August 10.
