In an effort to cut down on carbon emissions produced by the hundreds of thousands of cars and trucks on the road every day, alternative fuels, namely electricity and hybrid powers, are making great strides in becoming the vehicles of the future. But cars and trucks aren’t the only way people get around. Airplanes notoriously use huge amounts of fuel, and up until recently, this fuel was petroleum-based. But as the concern over the non-sustainability of fossil fuels mounts, some airlines are looking to alternatives.
Recently, Alaska Airlines flew 75 commercial flights using planes powered with biofuels, which were derived mainly from used cooking oils, like the kinds found in deep-fryers. While biofuels can be pricey at this stage for airlines, they are hoping that with more research, biofuels can be a viable alternative to fossil fuels. Alaska’s flights used a mixture of biofuel and traditional petroleum-based fuel, and the choice to use old cooking oil was made so that biofuel collection would not compete with or otherwise put a strain on food production. Now, other airlines are looking into petroleum alternatives as well. Check out some of the links below to learn about this new trend in aviation.
