A 100 kW rooftop can be a meaningful source of energy savings—and a difficult project to finance. How do you make solar work for affordable housing, churches, and nonprofits? In this episode of the Clean Power Hour, Tim Montague sits down with Ben Underwood and Isaac Baker, founders of Massachusetts-based Resonant Energy, to discuss how they built a solar development business around nonprofits, houses of worship, and low-income multifamily housing. Ben and Isaac explain how a portfolio approa...
Rising electricity demand and prolonged outages are pushing the Tennessee Valley to rethink how it builds and operates the grid. Where do solar, batteries, and community-scale microgrids fit? In episode 374 of the Clean Power Hour, Tim Montague welcomes Gil Hough, Executive Director of the Tennessee Solar Energy Industries Association (TenneSEIA), for a conversation following the organization’s 2026 conference. Gil explains how the Tennessee Valley Authority (TVA) shapes this distinctive publ...
Solar and storage are moving into a new phase, and this week's Clean Power Hour Live covers the technologies, policies, and market shifts shaping that transition. Tim Montague and John Weaver break down the latest developments across solar, batteries, wind, grid infrastructure, and electrification. In California, Governor Gavin Newsom has signed legislation supporting virtual power plants and making plug-in solar officially legal.
