This week on the show, we meet someone on a mission: to decarbonize America’s buildings. Decarbonizing buildings is is actually a huge piece of decarbonizing our economy: carbon pollution from heating, cooling, and powering our buildings accounts for 30 percent of U.S. carbon emissions – that includes our homes, schools, hospitals and office buildings.  So is it possible to decarbonize all of our buildings – and make strides in health and economic development at the same time? Our guest this week, Keith Kinch, thinks so. He’s the co-founder of BlocPower, a company that’s electrifying buildings across the country. He walks us through a road map of what it’s going to take to get our buildings to net zero.  Guest: Keith Kinch is General Manager and co-founder of BlocPower.
