Mynydd y Betws is the site of a wind turbine farm. It was granted planning permission in 2009 and started producing electricity in 2013. The original developers of the site were the renewable energy generating company Eco2, but in 2010, they sold the site to the Irish state-owned electricity utility ESB. The mast of each turbine is tall and the blades are long. With fifteen turbines, the wind farm has an installed capacity of 34.5 MW and is said to generate enough electricity to power 23,800 households, one third of the domestic usage in Carmarthenshire. The Mynydd y Betws Wind Farm community benefit fund provides grants for projects in neighbouring areas of Carmarthenshire, Swansea and Neath Port Talbot.
