Electrifying 60 Million US Homes Without Overloading the Grid Artwork

Climate Confident - Practical Climate Solutions That Cut Emissions

Climate Confident is for business leaders, climate professionals and policymakers who need to understand what is actually cutting emissions—and what it takes to make those solutions work at scale.

Each Wednesday, I speak with the executives, engineers, scientists, founders and policymakers turning climate ambition into measurable progress. Together, we examine the technologies, business models, policies and implementation strategies reshaping energy, transport, industry, supply chains, food and finance.

These are not conversations about distant targets, vague pledges or greenwash. They are candid discussions about what is working, what is failing, where the real bottlenecks lie, and how leaders can make better decisions about decarbonisation, resilience, investment and risk.

You will hear:

Proven approaches to reducing emissions
Hard-earned lessons from real-world implementation
Analysis of the markets, technologies and policies driving the transition
Honest examination of costs, trade-offs, setbacks and unintended consequences
Practical ideas for turning climate commitments into action

New episodes are published every Wednesday at 7am CET. Subscribers also receive bonus episodes featuring highlights, analysis and emerging themes from across the series.

Follow Climate Confident for practical climate solutions, informed debate and the insights you need to turn ambition into measurable progress.

What if upgrading your home to be climate-friendly was as simple as scanning it with your phone?

In this week’s episode of the Climate Confident Podcast, I talk with Grant Gunnison, founder and CEO of Zero Homes - a former NASA and MIT engineer who’s now tackling one of climate tech’s toughest challenges: decarbonising existing homes. His company uses smartphone scans and digital twins to design fully-scoped, permit-ready electrification plans - no site visit, no clipboard, no chaos.

You’ll hear how Grant’s team is cutting out the “truck rolls” that make home upgrades expensive and slow, saving homeowners money while helping contractors stay profitable. We dig into why electrifying 60 million U.S. homes is both an engineering nightmare and a golden opportunity, and how technology, not policy alone, can finally make it scale.

We also unpack the human side: what really motivates homeowners to switch to heat pumps, why induction cooking is a secret health win, and how removing the awkwardness of having strangers poke around your home can actually accelerate climate action.

🎙️ Listen now to hear how Zero Homes is reshaping the future of home electrification - making sustainable living smarter, faster, and far more comfortable.
