Redefining Energy

Where is Climate Tech heading? Certainly not dead — but constantly reinventing itself. So much so that you begin to wonder whether the label itself has outlived its original meaning.  

Laurent and Gerard welcome Kim Zou, co-founder and CEO of Sightline Climate, the data and research platform mapping the climate-tech economy, and author of some of the sector’s most influential newsletters, including CTVC and the newer Powerstack. Sightline has become essential reading for investors, utilities, corporates, and policymakers trying to understand where capital is flowing and how the energy system is evolving.  

Together, they explore how Climate Tech has transformed over the past decade. Decarbonisation alone is no longer the central narrative. Today, AI, energy security, and industrial resilience dominate the conversation — often pushing sustainability itself into the background.  

The discussion traces how funding has shifted from venture capital toward infrastructure and large-scale project finance. The spotlight has also moved away from “green molecules” — hydrogen, SAF, and carbon management — toward “green electrons”: virtual power plants, grid-enhancing technologies, and the race to accelerate datacentre construction.  

They also examine the contrasting innovation models shaping global competition. In China, much of the breakthrough innovation happens inside corporations themselves, with companies like BYD employing more than 110,000 R&D staff, and CATL relying on a 20,000-engineer workforce. The United States, meanwhile, benefits from unparalleled access to capital and world-class universities and research centres. Europe sits somewhere in between, attempting to combine industrial policy with scientific excellence.  

Finally, the conversation turns to one of Sightline’s newest areas of focus: tracking data-center construction. The company currently follows 140 sites representing roughly 16 GW of announced capacity. Yet only about 6 GW are actually under construction — a reality check that has sent a chill through Wall Street.

And Laurent goes on a rant of epic proportion against certain Hyperscalers!!!

The power system is aging and poorly equipped to handle the rapid, large-scale shift toward renewables. According to Philipp Schröder, CEO of 1KOMMA5°, the real solutions lie “behind the meter.”  

Gerard and Laurent sit down with Schröder to unpack what it will take to unlock the so-called “Behind the Meter” revolution.  

Schröder is among a small group of European founders aiming to build a vertically integrated, consumer-focused clean energy company—something akin to a European hybrid of Tesla Energy and Sunrun. His approach combines hardware (such as solar PV systems, home batteries, heat pumps, and EV chargers), installation networks, intelligent software (including IoT-driven energy management like “Heartbeat”), and active participation in energy markets.  

Software is becoming increasingly critical. Grid management and pricing systems remain outdated and inefficient, especially in Germany, where reform has been slow due to entrenched interests and the slow deployment of smart meters. By contrast, countries like Sweden are already moving ahead with more modern approaches.  

The company’s growth appears to validate this strategy. 1KOMMA5° now employs over 3,000 people, is approaching EUR1 billion in annual revenue, and has raised EUR400 million from investors including Eurazeo, CalSTRS, and several prominent family offices.  

Key questions remain: How does Schröder position 1KOMMA5° against competitors like Octopus, Enpal, Base, and Thermondo? Is he building the next kind of utility—or deliberately staying outside that model? And how does he navigate policy challenges, particularly when engaging with energy leaders in Germany who remain supportive of fossil fuels?  

A fascinating conversation with a formidable entrepreneur who gives back literally “Power to the People”.

Gerard and Laurent welcome Tinne Van der Straeten, CEO of WindEurope—the leading voice of the wind industry in Europe, representing more than 600 members across the entire value chain. Tinne brings a distinctive perspective to the discussion. As Belgium’s Minister for Energy during the 2022 Russian invasion of Ukraine, she experienced an energy crisis firsthand. Her background in policymaking offers a different vantage point from that of investors, shaped by the practical realities and trade-offs of government decision-making.  

The conversation highlights that, despite ongoing challenges, wind energy continues to expand rapidly across Europe, with €45 billion in final investment decisions recorded in 2025. There is now a clear opportunity to repower first-generation onshore turbines, which could double installed capacity and potentially triple electricity generation. Offshore wind also stands out as a major growth area, with the North Sea remaining the central hub, while the Baltic Sea is developing steadily and early signs of momentum are emerging in Spain.  

At the same time, the discussion points to the persistence of outdated, ideologically driven debates around energy sources—such as gas in Germany or nuclear in France—which increasingly feel disconnected from current realities. Policies like bans on onshore wind in Poland and offshore wind in Sweden illustrate decisions that risk slowing progress.  

A central theme is the urgent need to electrify demand, particularly through the adoption of electric vehicles, heat pumps, and the expansion of data centers.  

The conversation concludes by emphasizing that the missing piece is a large, integrated pan-European grid—potentially extending to Canada—combined with battery storage. Such infrastructure would accelerate decarbonization, support economic resilience, and help Europe regain control over its energy future.

Ember released its 2026 Global Electricity Review (GER26) last week—an extraordinary report showing that 100% of new global electricity generation has been met by renewables. At the same time, the decade’s “twin energy shocks” (Russia in 2022 and Hormuz in 2026) are accelerating existing trends.  

What do the latest numbers tell us—and what do they mean? Laurent and Gerard are joined by a great friend of the show, Kingsmill Bond, Lead Energy Strategist at Ember, to break it all down.

They begin with the GER’s key findings, looking closely at China, the United States, Europe, and India. The figures are striking: in 2025, wind and solar alone accounted for all net global power growth—roughly equivalent to Japan’s total electricity consumption. And even that may be an underestimate, given likely gaps in data from Africa and behind-the-meter generation.  

From there, the discussion shifts from long-term trends to sudden shocks. These shocks act as accelerators. Consumers, responding quickly, are installing rooftop solar and buying electric vehicles at record rates. Governments, by contrast, often move more slowly, seeking to protect incumbents and hoping for a return to the old status quo. But that return is increasingly unrealistic.  

Looking beyond the numbers, the episode explores how energy shocks reshape the system. The oil shocks of the 1970s drove gains in efficiency and a wave of nuclear investment. Today’s shocks are pushing electrification, expanding renewables, and speeding up EV adoption.  

Four major long-term implications stand out: 1) Asia is set to electrify faster than the rest of the world 2) Transport electrification will accelerate 3) LNG will be pushed out of the power sector 4) The long-anticipated “peak oil demand” is drawing closer.   

In summary, we are shifting from a world defined by range anxiety to one increasingly shaped by pump anxiety.

In episode 219, we analysed the relationship between hyperscalers and US utilities from the hyperscaler perspective. To complete the picture, we revisit the debate from the utility’s point of view.

Gerard and Laurent welcome Rajiv Bazaj, VP of Solutions Sales at Constellation, to understand how utilities approach this rapidly evolving landscape. Spun out of Exelon a few years ago, Constellation was initially seen as the “ugly duckling,” but it was sitting on a major advantage: a large nuclear fleet. What was considered a liability in the 2010s has become a strategic asset as hyperscalers search for clean, reliable 24/7 power.

The acquisition of Calpine and its large CCGT fleet turned Constellation into the largest US utility in terms of capacity, with around 60 GW (half nuclear, half gas) and roughly 200 TWh of annual generation—placing the company at the centre of discussions with hyperscalers and data centre developers.

Constellation’s approach remains cautious. The company is only gradually moving into batteries, is bullish on demand response following the surge in PJM capacity prices and is exploring upgrades to its nuclear fleet while remaining sceptical about. Geothermal. where the Company is active, is attractive but seen as difficult to scale.

The overall picture is one of disciplined conservatism. Constellation cannot easily be pushed by aggressive data centre developers because it already has the right generation mix at the right time. Its core objective is simple: maximise fleet load factors and sell MWh at the highest possible price. Gas assets operate in the mid-merit order with strong spark spreads, while nuclear requires higher long-term prices to justify further investment, as illustrated by the Microsoft-supported Three Mile Island restart.

With around 90% of its capacity built in the 20th century, Constellation is focused on upgrading and optimising its existing fleet rather than pursuing large-scale expansion. For hyperscalers, understanding this mindset is key when engaging with utilities.
