An innovative start-up is targeting a low-tech problem with high-tech solutions. With about 70% of New York City’s greenhouse gas emissions coming from its buildings, for Brooklyn native Donnel Baird the solution is simple: bring green power to those who need it most, block by block. Baird is the founder of BlocPower, a Brooklyn-based company working to green American inner-cities using cutting-edge data analysis and green energy solutions. Baird takes the NYC Rising crew door-to-door in Brownsville, Brooklyn, one of the poorest neighborhoods in New York City, to see his vision already coming to life with an unprecedented number of solar-panel installations in a single community. What would it take to reduce greenhouse gas emissions in the U.S. by two to three percent in five years?
