CleanTalk

Need help turning an idea into a real product? Work with Hard Stuff to build your MVP today: https://www.hard-stuff.com/__________________________In this episode of CleanTalk, we sit down with Matt Stedman, a startup engineer and fractional CTO who helps early-stage companies turn ambitious ideas into real, working products, particularly in climate and clean technology.We explore what founders consistently get wrong when building MVPs, why “perfect” products are often the enemy of progress, and how marrying yourself to a solution instead of a problem can quietly kill a startup. Matt shares hard-won insights from working with hardware founders, from breaking perfectionism to testing whether anyone will actually pay for what you’re building.We also dig into why climate tech isn’t just about big infrastructure and renewables, how niche physical products can make a meaningful impact, and why building “stuff that matters” requires humility, iteration, and the willingness to fail fast.This episode is for startup founders, engineers, climate tech builders, product leaders, and anyone navigating the messy early stages of turning an idea into something real, especially when time, money, and certainty are in short supply.Enjoy!__________________________Connect with Matt on Linkedin: https://www.linkedin.com/in/m-a-stedman/Join the CleanTalk community on Linkedin:https://www.linkedin.com/groups/12991627/__________________________CleanTalk is produced by Harmer Visuals, a film & media company specialising in brand & case study storytelling for organisations across the renewable energy and clean technology sector.

The film documents the reality of working at height, sea survival, fire awareness, manual handling, and first aid, and why these skills are non-negotiable for anyone working on or around wind energy infrastructure.In today's discussion, Iain shares insights from decades working offshore across oil, gas, and wind. We talk about dynamic risk assessment, complacency as a leading cause of incidents, how training must evolve as turbines move further offshore and increase in scale, and why human judgement still matters even as automation and robotics improve.Audio-only listeners: this episode includes short excerpts from the full vlog. You’ll still get plenty of value listening, but for the best experience we recommend watching on YouTube or Spotify.This episode is for offshore wind technicians, safety professionals, trainers, operators, engineers, and anyone curious about what it really takes to keep people safe while building the energy system of the future.Enjoy!Connect with Iain on Linkedin: https://www.linkedin.com/in/iain-tindall-8137817b/Join the CleanTalk community on Linkedin:https://www.linkedin.com/groups/12991627/CleanTalk is produced by Harmer Visuals, a film & media company specialising in brand & case study storytelling for organisations across the renewable energy and clean technology sector.

From there, the conversation opens up into three deeply interconnected themes: systems thinking, infrastructure, and intergenerational responsibility.We explore why energy systems are often invisible despite shaping everyday life, how Europe’s electricity grid reflects decades (and centuries) of political and social decisions, and why renewable integration cannot be solved by engineering alone. Ivo breaks down systems thinking as a lens rather than a solution, a way of understanding complexity, feedback loops, and unintended consequences without pretending the world is simple.A major thread running through the discussion is youth engagement. Not as a branding exercise or slogan, but as a structural necessity. Energy infrastructure lasts for decades; decisions made today will be executed by people who currently have little formal power. Ivo argues that excluding younger and marginalised voices isn’t just unjust, it actively weakens the transition.We also tackle uncomfortable but necessary topics:- Why the energy transition is inherently political- Why disagreement and disruption are features, not bugs- Why labelling communities as “NIMBYs” misses deeper justice concerns- Why changing the goal of a system matters more than tweaking its rulesThe episode closes with reflections on learning, career uncertainty, and why inspiration usually follows action, not the other way around.This is a conversation for anyone working in energy, infrastructure, policy, research, or climate communication, especially those who sense that the hardest problems ahead aren’t technical, but human.Enjoy!__________________Connect with Ivo on Linkedin: https://www.linkedin.com/in/ivo-wakounig/Join the CleanTalk community on Linkedin: https://www.linkedin.com/groups/12991627/____________________CleanTalk is produced by Harmer Visuals, a film & media company specialising in brand & case study storytelling for organisations across the renewable energy and clean technology sector.

In this episode of CleanTalk, we sit down with Thaddeus Anim-Somuah, a corporate sustainability professional, chemical engineer, World Energy Council contributor, and advisor on impact and energy-transition investments, to explore how energy, materials, finance, and human behaviour are deeply interconnected, and why sustainability only works when it creates real value for people.Drawing on his upbringing in Ghana, his engineering background, and his work across industry, finance, and policy, Thaddeus unpacks the circular economy, material efficiency, behavioural change, sustainable finance, and the limits of “moralised” renewable energy narratives. We discuss why optimisation often matters more than abundance, how regulation like CSRD is reshaping corporate behaviour, and why finance, more than technology alone — will determine the pace of the energy transition.This episode is for sustainability professionals, engineers, investors, policymakers, founders, and anyone trying to understand how the energy transition actually works beyond slogans, marketing, and moral posturing.Enjoy!_______________Connect with Thaddeus on Linkedin: https://www.linkedin.com/in/thaddeusanimsomuah1/Join the CleanTalk community on Linkedin:https://www.linkedin.com/groups/12991627/_______________CleanTalk is produced by Harmer Visuals, a film & media company specialising in brand & case study storytelling for organisations across the renewable energy and clean technology sector.

This week on CleanTalk, Film Director-Producer Luke Harmer sits down with James Sterling, Communications and Social Value Manager at Bristol City Leap, to explore how one city is pioneering a socially just energy transition.In this episode, we dive into Bristol City Leap’s innovative approach to building a fairer, cleaner energy system — one designed not only to decarbonise but to protect the people who contribute the least to climate change from bearing the greatest cost. James unpacks how their model is creating a replicable blueprint for other regions and cities to follow, while ensuring that community voices remain central to the process.From tackling fuel poverty and embedding social value, to driving investment and inspiring wider systemic change, this conversation highlights what a just transition can look like in practice and why Bristol’s story could mark a turning point for the way we think about local energy systems across the UK and beyond.Enjoy!____________________Connect with James on Linkedin: https://www.linkedin.com/in/james-sterling-a96169104/Unlock support for decarbonising your home, business or community: https://www.bristolcityleap.co.uk/Join the CleanTalk community on Linkedin: www.linkedin.com/groups/12991627/____________________CleanTalk is produced by Harmer Visuals, a film production company specialising in brand & case study storytelling for organisations across the renewable energy and clean technology sector.
