Green Roofs - Innovation Nation

The video discusses the high temperatures of asphalt roofs and introduces a project supported by the National Science Foundation to transform these roofs into green, plant-covered spaces. Climate scientists Stuart Gaffin and Patricia Culligan are developing lightweight substrates for green roofs, which help cool urban areas, manage rainwater, and reduce the strain on electrical grids. The video emphasizes the potential energy savings and blackout prevention benefits of widespread green roof adoption.
