Energy transition

On 28 April 2025, a sudden blackout plunged the Iberian Peninsula into darkness. Within hours, renewables were blamed. Months later, experts found a voltage surge – not green energy – triggered the collapse. This article explores how blackouts fuel anti-climate disinformation and distort Europe’s debate on the energy transition.

When a series of power outages hit Europe last year, the finger of blame was quickly – and falsely – pointed to an unlikely source: renewables. Blackouts are being used as a political tool to oppose the energy transition. But they can also become an opportunity for open discussions about energy infrastructure – a topic too often reserved only for technical audiences.

Independent energy system operation is a live EU debate. The Commission may raise it in the Grids Package or White Paper. Institutional reform is slow and costly, but failing to deliver policy goals is far worse. We cannot wait to fail before acting.

Europe once set the standards the world followed. Today, others are pushing back, challenging the EU’s regulatory power and exposing its reluctance to act strategically. Our Böll EU Newsletter 11/2025 examines Europe’s shifting role in global power politics, the rise of the green euro, new debates on security and offensive capabilities, fresh insights on the MFF, and our latest work on citizen participation in the EU energy transition.

Europe’s energy transition has achieved a lot. The high share of domestic renewables in our energy mix buffered the fossil gas price crisis. During the last decade, solar power became the cheapest source of electricity, accessible at basically all citizens’ homes. So, if your bill goes through the roof, just put solar panels on the rooftop? Yes, but if things were so easy, the Green European Foundation (GEF) and the Heinrich-Böll-Stiftung European Union would not have worked with a knowledge community of 30 energy geeks and social policy nerds during the past year on how to let citizens benefit better from the energy transition

There are good reasons to wish for a future with more heat pumps: less fossil gas in the heating sector and therefore less methane leakage and less CO2 and NOx emissions; lower costs for households; and more energy independence for nations. Most of this works best with powering the heat pumps with a bigger share of renewables. In Europe, heat pumps boomed until 2023 and then dipped to 2020 or 2021 levels in 2024. Starting points and paces of change in the heat pump market differ wildly. Let’s have a virtual trip to Sweden, France and Germany and find out why those timelines are so different.

For citizens, the energy transition brings many opportunities to cut their bills. They can benefit from cheap renewables, for instance by using solar power from their rooftop. They can reduce their energy consumption, for instance through energy efficient appliances or building renovation. They can also use renewable electricity to move from one place to another. But not every household can afford the new technologies such as solar photovoltaic panels, electric vehicles or heat pumps. The EU offers several rights and regulations that facilitate citizens’ fair participation in the energy transition. Explore our infographic to see which tools make it easier to benefit from the different technologies. This will empower households to escape from rising fossil fuel prices.

New policy briefs by a broad range of stakeholders in energy and social policy outline key levers for the EU to improve citizen participation and inclusion in the energy transition. 

Levies, charges, and taxes make electricity expensive – and hinder the switch to the climate-friendly, electricity-based alternatives that we urgently need. Yet many companies and consumers have long been ready to make the change. The technology is already available, often from German manufacturers, who have been waiting for years for a market breakthrough. Instead, Katherina Reiche's reckless wrong-way drive continues unabated.

As Europe’s energy system shifts from fossil fuels to decentralised renewable energies, one challenge is coming into focus: how can the rising costs of expanding and modernising the electricity grids required for the transport of renewable power be financed fairly and efficiently? And how can tariff design help reduce pressure on the grid by encouraging consumption patterns that make better use of existing infrastructure?    

Five months into the new European Commission, the Heinrich-Böll-Stiftung European Union is releasing an updated European Green Deal Risk Radar, spotlighting critical risks to the EU’s climate, environmental, and sustainability laws in the 2024–2029 legislative term.

The EU promised a renewable energy future – but is it still on track? As political shifts, policy delays and legal battles unfold, the energy transition faces new hurdles. Are we still moving forward, or is Europe starting to backpedal? Seden Anlar reports.

The European Commission has unveiled its new strategy to make EU industries more competitive with cheap energy. Does this mean the bloc will go full speed ahead in terms of building more wind farms and solar power plants? Jörg Mühlenhoff looks into what the details of the Clean Industrial Deal mean for Europe’s energy transition.

Are ‘highly energy-efficient and sustainable’ data centres by 2030 realistic? Jessica Commins and Kristina Irion argue that despite efficiency measures, unchecked sector growth threatens sustainability. This post presents ten elements that will be key in the development of the iteration of the EU data centre sustainability policy.

Most Britons have no intention of installing a heat pump. Given the cost of electricity in the UK, that’s not unreasonable. Ros Taylor looks at why it is so hard to tempt them away from gas boilers.

Three years after Russia’s full-scale invasion of Ukraine, Paul Hockenos compares the efforts of the EU and the US in view of weaning from Russian fossil fuels. On the ground, Ukraine’s transition to distributed renewables already rhymes with resilience against the aggressor.

Boosting passenger train transport is key for reducing greenhouse gas emissions of transport and for accelerating Europe’s energy transition. Are EU railways on track? Establishing a fair picture of the state of Europe’s passenger railways is a hard task. It is essentially a question of whether you see the train as half full or half empty. Jon Worth reports.

Something sounds awry about the term ‘twin transition’. The concept, often used in EU or UN contexts, ties two crucial transitions: the move to renewable energy and the digitalisation of economies. While it sounds forward thinking, evidence suggests this pairing may be less beneficial than promised. As developing countries bear the socio-environmental costs while reaping limited benefits, a handful of tech giants continue to dominate global markets. Paz Peña raises a crucial question: is this ‘transition’ truly a path to equity, or does it deepen old divides under the guise of green progress?

The green technologies needed to rapidly cut our greenhouse gas emissions are already on the market. What’s more, they are, or very soon will be, cost effective. In other words, from the perspective of the household, it is, overall, cheaper to go green. However, there’s a catch: access to capital is king in the household energy transition. 

On 18 July 2024, European Commission President Ursula von der Leyen was elected for a second mandate and presented to the European Parliament her Political Guidelines for the next European Commission. A new European Commission will kick-off its work on 1 December 2024, after its approval by the European Parliament. We take a look at von der Leyen's promises for the first 100 days (and beyond) of the new European Commission.
