Everyone knows that wind and solar have significant carbon footprints because of the energy and materials that go into the manufacture of their components. It’s why research continues on how to get that footprint down. Emily Mercer at NREL describes research there that has developed a glue, used to hold a wind turbine blade together, made of resin made from plant waste using a low-energy process, and is easily recycled. In contrast to the current … [Read more...]
