Green in brief: MountainTr­ue seeks ban on single-use plastics

A study conducted by MountainTrue found an average of 19 microplastic particles — pieces smaller than 5 millimeters, formed by the breakdown of larger plastics — per liter of water in local river systems. Exposure to microplastics has been tied to allergic reactions and other health impacts in humans, as well as negative effects on fish.

Heat pumps drive rapid growth in WNC’s peak electricit­y demand

Using data provided by Duke Energy, a local task force has shown that much of the growth in WNC’s peak electrical demand is driven by the conversion of existing oil- and propane-fired heating systems to electric heat pumps. Slowing the growth in peak demand is the mission of the task force, which hopes to delay or eliminate the need for one of three new power plants proposed for Duke Energy’s Lake Julian station.
