It's official: New York just gave the green light to build the largest offshore wind farm in US history. The project will be located 30 miles southeast of Montauk, and it will produce enough energy to power 50,000 homes. Meanwhile, researchers have developed a revolutionary new wind turbine that trades spinning blades for flapping wings reminiscent of a hummingbird. Dubai kicked off phase three of the world's largest solar park. When it's complete it will produce a whopping 800 megawatts of clean energy. Speaking of the sort, Elon Musk is a champion of clean energy -- so imagine our surprise when Musk threw his support behind former ExxonMobil CEO Rex Tillerson as Secretary of State. And Ireland just voted to become the world's first country to fully divest from fossil fuels.
