John Berger has won big and lost big. He founded Sunnova out of his Houston apartment in 2012 and grew it into one of the largest residential solar companies in the country, before it ended in bankruptcy. Now he’s back as CEO of Otovo, betting that the next big solar business isn’t installing panels but keeping them running. In this far-ranging conversation with host Elisa Wood, Berger explains why installation and service are two different businesses, what it means for a solar system to be “orphaned,” and why he built a company that avoids heavy debt and policy exposure. He also shares why he wishes the Inflation Reduction Act had never been so politically visible, why data centers and oil producers are turning to behind-the-meter power, how Otovo is using AI to run service operations, and whether humanoid robots could soon be working in the field. Plus: Europe as a “sleeping giant,” balcony solar, and what eating glass has to do with entrepreneurship. Subscribe to the Energy Changemakers newsletter free at energychangemakers.com.

Utilities and distributed energy companies often talk past each other, and each side blames the other for the stalemate. Navneet Trivedi, co-founder and COO of Vrinda Inc., has spent more than three decades working with over 100 utilities in eight countries, and he calls himself an "energy transition realist." In this episode, host Elisa Wood talks with Navneet about why utilities behave the way they do, why he called New York's REV initiative flawed when everyone else was celebrating it, and his proposal to change the relationship. If batteries, microgrids, and other DERs make customers more resilient, Navneet asks, should responsibility for reliability, and the pay that comes with it, be shared between the grid and distributed resources? It's a candid conversation from someone who loves utilities and wants them to change. Check out Vrinda's latest white paper: https://energychangemakers.com/resource-library/grid-utilization/

Autonomous vehicles are more than cars without drivers. They’re “robots on wheels” — and they will need enormous amounts of electricity at the grid edge. In this episode of the Energy Changemakers Podcast, host Elisa Wood talks with Mike Calise, CEO of EV charging company Tellus Power, about why the rise of autonomous fleets could make microgrids and distributed energy a strategic necessity. Calise sees two massive transformations colliding: the electrification and automation of transportation, and a power system already confronting soaring demand from AI and data centers. Microgrids could help bridge the two by generating and managing electricity close to where autonomous vehicles operate — while bidirectional charging allows the batteries inside those vehicles to become grid assets rather than simply new loads. The conversation explores a real-world example at Oakland Unified School District, where 74 electric school buses can act as dispatchable batteries, returning energy to buildings or the grid when the buses are sitting idle. It also looks ahead to robotaxis, delivery vehicles, drones and other forms of “physical AI” — and what it will take to power them as they scale. Calise calls it a collision between the multi-trillion-dollar energy and transportation industries. At the center of that collision may be one of distributed energy’s biggest opportunities yet: using microgrids, storage and vehicle-to-grid technology to power the machines emerging at the edge.

What if the model to solve many of our biggest electricity problems already exists—we've just never used it to its full capacity? In this episode, Keith Taylor, a UC Davis  institutional economist, makes the case that America's 800-plus co-ops are a form of "latent community capacity" hiding in plain sight. Keith proposes federating cooperatives so that they compete in the microgrid era, and what a Lake Tahoe utility crisis reveals about who really gets served when data centers come knocking. It's a hopeful, practical conversation about doing "policy from below." Look beyond the market and the state. Drawing on Nobel laureate Elinor Ostrom's insight that "there are no panaceas," Keith argues we systematically overlook the civic economy — a third leg of the stool alongside the market and government — where cooperatives operate on logics of service at cost rather than profit. We already have energy democracy. The U.S. has more than 800 electric cooperatives serving roughly 42 million Americans, generating about $42 billion a year in revenue. Of those members, some 8,000 serve as elected board directors — a political economy of its own that's ready to be leveraged, not built from scratch. Co-ops are often more efficient, not less. Investor-owned utilities serve about 30 households per mile of line; the average co-op serves about 7 — yet co-ops deliver comparable rates. In the 1930s, IOUs claimed lines would cost $2,000/mile; co-ops innovated the cost down to under $650/mile. Keith sees the same pattern today in broadband, where a South Carolina co-op (Carolina Connect) is stringing fiber for ~$15,000/mile against incumbent telco estimates of $200,000–$300,000/mile. Small doesn't mean weak — they federate. Individual co-ops stay locally controlled but pool into federations for financing (CoBank, the National Rural Utilities Cooperative Finance Corporation, and USDA's Rural Utilities Service together hold over $300 billion in assets), insurance (Federated Insurance), and white-label marketing (Touchstone). Keith's vision: a "microgrid federation" that makes co-ops a trusted vendor for communities building distributed energy. The Tahoe warning. A pocket of ~50,000 Californians around Lake Tahoe is served by the Nevada grid — and as Nevada's data-center demand grows, that region may be dropped in about 18 months, facing spot-market rates and rolling blackouts. It's a concrete example of customers losing out to data centers, and of why platforming alternative institutional models matters. Policy parity works. Co-ops have lagged on renewables largely because of incentive structures — they were historically excluded from renewable subsidies and often exempt from state renewable portfolio standards. When the Inflation Reduction Act's "direct pay" provision finally gave them parity with IOUs, co-ops rapidly expanded their renewable and distributed-energy portfolios. Start local, start now. Keith's call to action is bottom-up: engage your co-op's board and member-relations staff, join a member advisory committee, or run for the board. Where there's no co-op, look to public utility districts, community choice aggregators, or form a new association. As Ostrom put it: "We can, so we must."

Most people in solar assume the industry started with the trade-show boom of 2006–2007. It didn't. It started decades earlier, in the logged-over hills of Humboldt County, California, where back-to-the-land hippies were hacking a self-sufficient life out of the wilderness — powering their homes off car batteries, micro-hydro, and windmills just so they could keep the lights on and play a little music. Host Elisa Wood sits down with filmmakers Jeff Spies and Jason Vetterli, whose two-hour documentary Solar Roots: The Pioneers of PV traces how an expensive military, space, and petrochemical technology found its way into the hands of ordinary people — and, in doing so, became a real industry. It's a story of catalog salesmen, off-grid homesteaders, cannabis-funded land deals, conservative ranchers won over one panel at a time, and a scrappy magazine that connected them all. Along the way, Jeff and Jason make the case for why solar has already won the price war, why the remaining fight is cultural, and why this history had to be captured now, while its pioneers are still here to tell it.

From homeowners to businesses to AI data centers, customers are investing in distributed energy for their own reasons — and collectively rewiring how the entire electric system evolves. Recorded live to open The Great Transformation conference in Bend, Oregon, host Elisa Wood sits down with three people who aren’t just watching this shift — they’re shaping it: Cameron Brooks of Think Microgrid, Greg Castle of Schneider Electric, and Mike Grenier of Elexity. The panel digs into the data center power boom (a reported 114 GW of behind-the-meter generation in the pipeline — roughly 20% of U.S. peak load), why falling battery prices are flipping "two yeses out of ten" into "eight," the "Frankenstein microgrid" phenomenon, and how flexible interconnection deals in New Jersey and the Google–Voltus capacity agreement point toward a grid that’s built from the outside in. It’s a candid, optimistic conversation about ownership, resilience, and scaling what already works.

Wildfires, record heat, and a grid under more strain than ever have turned “resilience” from a buzzword into one of the fastest-growing categories in energy technology. Host Elisa Wood talks with Julia Hamm — who spent nearly 20 years growing the Smart Electric Power Alliance (SEPA) before becoming a partner at The Ad Hoc Group — about how resilience became its own market, the AI cameras and wildfire-spread software utilities are deploying today, why microgrids are still an emerging (not mainstream) resilience play, and why the length of the utility sales cycle remains startups' biggest obstacle. They also discuss why Julia launched the Power Resilience Forum to keep this conversation from being crowded out by the AI and data-center load-growth story dominating the industry right now.

Plug-in solar — widely known as “balcony solar” — is one of the fastest-growing entry points into clean energy, and it is finally gaining a legal foothold in the United States. In this episode, host Elisa Wood talks with Stephan Scherer, co-founder and CEO of CraftStrom, who spent roughly a decade in the European plug-in solar market before bringing the technology to the U.S. The conversation unpacks what plug-in solar actually is, how small systems can offset a meaningful chunk of a household's electricity bill for a fraction of rooftop-solar costs, and why the technology sidesteps the interconnection agreements and “soft costs” that make traditional residential solar expensive. Scherer addresses the two big safety debates head-on — line-worker protection and grid export — and explains the certifications, anti-islanding shutoffs, and “zero-export” approaches that underpin safe deployment. They also explore the technical breakthroughs that made plug-in solar practical (lightweight bendable panels, integrated Wi-Fi monitoring, simplified installation), the economics and payback math, the addition of plug-in batteries and virtual power plants, and the wave of state laws — now five enacted — reshaping access for homeowners and renters alike.

The grid is straining under AI-driven demand, aging infrastructure, and climate-fueled weather events — and Robert W. Cross believes the answers already exist. The harder question is whether the industry can come together to deploy them. In this episode, host Elisa Wood talks with Cross, founder of Cross Consulting and principal at the cleantech design studio Outfit, about why distributed energy may be the relief valve utilities need, why storytelling is the industry's most underrated tool, and what he's building at The Great Transformation 2026, a curated, single-track summit in Bend, Oregon (July 8–10). They dig into the collision between an "irresistible force" — distributed energy resources — and the "immovable object" of the legacy utility model, the gap between feasibility and bankability, and why Cross is intentionally designing his event to create constructive professional conflict. It's a candid conversation about scale, finance, policy whiplash, and the case for getting builders, bankers, regulators, and dreamers into the same room.

Electricity prices are rising, data centers are struggling to connect, and consumers are feeling the pinch — yet utilities keep reporting record earnings. What's going wrong, and how do we fix it? In this episode, Elisa Wood speaks with Michael Lee, former CEO of Octopus Energy US and founder of Distributed Grid, about the structural flaw at the heart of the American utility model: an incentive system that rewards building infrastructure regardless of whether it is needed. Lee argues that this cost-of-service model — largely unchanged for a century — is driving an inflationary spiral in electricity rates and blocking the distributed energy resources that could make the grid more affordable and resilient. But his argument is not simply that utilities are bad actors. It is that utilities are rational actors operating under the wrong rules. Change the rules — and the business model — and utilities could earn more revenue by coordinating a decentralized grid than by building poles and wires. Lee lays out a detailed roadmap: from reframing utilities as "network coordinators" to paying them for outcomes (reliability, affordability, speed to power) rather than capital deployed. He also confronts the political and social complexities — utility shareholders who depend on dividends, governors who fear blackouts, and a public that has never had to think about how electricity works. The conversation is both an indictment of the status quo and a genuine blueprint for a better grid.

This episode revisits one of the most-listened-to conversations in Energy Changemakers history—a three-way dialogue between Kay Aikin (CEO of Dynamic Grid, Maine), Lorenzo Kristov (independent grid market architect and formerly of California ISO), and Mark Paterson (Principal and Lead Systems Architect, Energy Catalyst, Australia). The original episode aired in 2024; this return engagement goes deeper, reexamining the concept of energy abundance through a more refined and urgent lens. The conversation takes direct aim at the dominant political narrative of “generate, generate, generate”—the idea that energy problems are simply solved by producing more power. The guests argue that this approach confuses quantity with quality, and supply with access. They introduce the concept of “smart abundance” versus “dumb abundance,” and make the case that a truly abundant energy future must be planned from the bottom up, starting closest to the user, not at the distant bulk power system. Ranging across economics, physics, regulatory law, and systems theory—and drawing analogies from photosynthesis to mycelial forest networks to Windows 97—the three guests explain why the current grid architecture is structurally incapable of delivering on the promise of energy abundance, and what reforms in planning, regulation, and market design would make the transformation possible. Australia’s experience with surplus renewables and minimum system demand serves as a real-world case study of what happens when abundance arrives without the right operating system to manage it.

The Pew Charitable Trusts has released a long-awaited policy playbook for scaling distributed energy resources (DERs) across the United States. In this episode, host Elisa Wood sits down with the two co-chairs of the Pew DER Advisory Council — Audrey Zibelman and Pat Wood III — to unpack what the playbook says, why DER deployment has stalled despite a clear business case, and what policymakers can do right now to change the trajectory. The conversation moves from high-level regulatory philosophy to the practical mechanics of utility incentive design, FERC jurisdiction, virtual power plants, and the pros and cons of America's 50-state laboratory approach to energy regulation. Both guests bring decades of first-hand experience reshaping the grid — Zibelman from New York's REV framework and Australia's national DER strategy, Wood from opening the Texas and wholesale power markets.
