From development to financing to construction to operations, Alexandre Cleret is right at the center of it at Decade Energy, making sure things move in the right direction.

As our Co-Founder and Chief Operating Officer, Alexandre leads our IPP team which covers: Sales, Infrastructure, Financing and Energy Markets teams. He also plays a key role in shaping company strategy, ensuring that Decade Energy moves toward its mission.

From Launching Companies to Reshaping Energy Systems

Before co-founding Decade Energy, Alexandre built a career at the intersection of entrepreneurship and energy. He’s scaled high-growth teams, structured complex financing deals and led the development of over €250 million worth of renewable energy projects, spanning wind, solar, battery storage (BESS) and green hydrogen.

Alexandre has worked across a range of large-scale projects, from supporting the rollout of electric trucks and charging infrastructure to developing a 132MW wind farm in Poland that replaced coal-fired generation, contributing directly to Europe’s CO2 reduction. 

“It’s one thing to talk about reducing emissions,” he says, “it’s another to help make it happen, megawatt by megawatt.”

Why Decade Energy, Why Now

For Alexandre, Decade Energy brings together everything he’s passionate about: renewable energy, electric mobility and building companies that scale fast.

“27% of EU emissions come from energy. 24% come from transport. That’s more than half, and it’s where the real work needs to happen,” he explains. 

“Decade Energy gives me a chance to combine everything I’ve worked on and go all-in on impact.”

He’s clear-eyed about the urgency: “We’re in the middle of an unstoppable transition. Renewables, BESS, EVs – they will take over. The question is how fast. Speed matters.”

Tackling the Next Big Challenge

When it comes to decarbonization, Alexandre sees one critical blind spot: depots. These logistical hubs are set to become some of the biggest energy consumers in Europe, but most of them aren’t ready for what’s coming.

“Depots are where transport and energy intersect. They’re the frontline of the EV transition,” he says. “At Decade Energy, we’re helping make them electrification-ready, quickly and cost-effectively.”

"We’re in the middle of an unstoppable transition. Renewables, BESS, EVs – they will take over. The question is how fast. Speed matters.”

What Drives Him, In and Outside of the Office 

Alexandre has been focused on the energy transition since 2018, when he decided to shift his career towards work that directly supports decarbonization. “This is my life mission,” he says, and a commitment that’s shaped his path ever since.

Colleagues describe him as thoughtful, driven, and open-minded, with a steady focus on what’s ahead. Outside of work, he enjoys cycling, spending time with his family and wingfoiling when the conditions are right. He’s also a certified sailing skipper – a skill that reflects his love of being out on the water and navigating with intention.

Over the coming weeks, we’ll share more about the people behind Decade Energy, on what they’ve done before, what brought them to Decade Energy and on their motivations and learnings so far.
