Sunday, September 21, was a national day of action on climate. SUN Day had a particular focus on promoting solar and other renewable energy sources such as wind and geothermal to respond to global warming. In Albany, there were displays and workshops beneath the Egg at the Empire State Plaza. Workshop topics included packaging reduction, solar, and how your local community can promote sustainability. We talk with Paul Fisk about why the stock transfer tax is a climate solution; Sue Cottner of the Green Energy Hub; Brennan Howell of Capital District DSA and the Public Power Coalition; Monica Gray of the Hudson-Mohawk Group of the Sierra Club; Hannah Miller of RPI Sunrise; and Bruce Frishkoff of Citizens Climate Lobby.
