Clean tech, minus the hand-waving.
Less Talk, More Action is a brisk clean-tech and decarbonization interview show with a practical chip on its shoulder. It likes founders, builders, policy fights, and climate claims that survive contact with installation, financing, and regulation.

Less Talk, More Action covers climate business from the implementation side of the table. It is not especially patient with vague ambition. The show keeps returning to a useful test: does the thing work, can anyone install it, will customers use it, and does the money make sense? Joel Caesar and Owen Barrett bring a loose, argumentative rhythm to interviews with founders, educators, nonprofit leaders, and operators across clean energy and decarbonization. The tone is conversational, but the questions are practical. A commercial-building plan is not finished because it looks good in an annual report. It has to move into retrofits, consultants, software, tenant realities, and the people who actually execute the work. A heat pump is not just a climate symbol. It is hardware, HVAC distribution, utility resistance, customer education, and legacy partners. The show is at its best when it treats overlooked systems as serious climate infrastructure: hot water, coastal ecosystems, discarded fishing nets, HVAC training programs, and household electrification all get time here. It also has room for irritation. Solo episodes can turn into pointed arguments about regulation slowing down green building work, with examples from composting toilets, water rules, and municipal permitting. Guest episodes often start with a bit of skepticism, then sharpen into admiration when the work proves concrete. Kevin Wilden’s coastal ecosystems work, Vincent Romanen’s heat-pump hardware, Luke Winston Almanzar’s hot-water focus, Cooper Marcus’s fossil-fuel quitting model, Bob Clark’s HVAC education energy, and David Stover’s fishing-net supply chain all fit the pattern. These are not soft-focus climate conversations. They are founder and operator conversations with impatience baked in. The show suits listeners who already believe decarbonization matters but are tired of hearing it treated like a branding exercise. It wants movement. It wants evidence. Above all, it wants fewer declarations and more systems that someone can actually put into use.
Made for: For clean-tech founders, building owners, sustainability operators, HVAC-curious listeners, and climate-business skeptics who want the practical version. It suits anyone who asks how decarbonization survives permits, budgets, utilities, and customer behavior.
What sets it apart: The show’s edge is its operator impatience: big climate ideas are pushed through cost, adoption, regulation, installation, and supply-chain reality. It can get excited about founders, but only after the hard parts are on the table.
The nexus of business, policy, and sustainability is more divided than ever, but Less Talk, More Action is here to cut through the noise. Hosted by clean energy experts Joel Cesare and Owen Barrett, this podcast dives into the front lines of decarbonization, net-zero real estate, and entrepreneurship. Each episode features bold questions, real solutions, and stories from leaders in science, tech, and business who are taking action to make the world a better place. Join us as we move beyond talk and work toward a cleaner, net-zero future.
