Farmers in many places have found additional sources of income by allowing wind turbines to be built on their land. One example is the Amazon Wind Farm, which is a massive project of over 100 turbines near Elizabeth City, North Carolina. The 494-foot tall turbine towers scattered over 34 square miles are rising up above farms that grow corn, wheat and soybeans. It is the first utility-scale wind farm in the Southeast.
The boom in natural gas drilling by conventional methods and by fracking has led to a spike in methane emissions from pipelines, storage tanks, processing facilities, and other parts of the natural gas system. Natural gas is mostly composed of methane, so these emissions constitute waste and lost revenues. But they also represent a serious environmental problem because methane is 25 times more effective in trapping atmospheric heat than carbon dioxide.
In March, United Airlines began using a new biofuel for flights between Los Angeles and San Francisco. The fuel is a renewable product called Honeywell Green Jet Fuel that can replace up to half of the petroleum jet fuel used in flight without any changes to the aircraft technology and it meets all current jet fuel specifications.
