Eight countries in Europe use renewables for more than half of their heating and cooling needs
ADVERTISEMENT
Russia's invasion of Ukraine continues to underscore the importance of energy security. Renewables play a key role in strengthening that security and diversifying energy sources.
The share of renewables has been rising across Europe, but it is doubtful that several countries, particularly the largest economies, will meet the EU's 2030 targets.
Upping the amount of
renewables
used to heat and cool buildings is especially important, as these uses account for nearly half of the EU's total energy consumption according to Eurostat.
So how much of Europe's heating and cooling energy comes from renewables? And which countries are leading the way?

In 2023, the share of renewable energy in heating and cooling reached 26.2 per cent in the EU, closely mirroring the proportion of renewables in the bloc's total energy use.
But this share varies widely across Europe - ranging from just 8 per cent in Ireland to 84 per cent in Iceland. Among EU members, Sweden and Estonia reported the highest shares, both at 67 per cent.
Why do some countries use more renewables in heating than others?
Renewable sources in the dataset include solar and geothermal energy, biofuels, the renewable part of waste, and ambient heat captured by
heat pumps
for heating.
Several factors explain the differences in renewable energy use for heating and cooling, Professor Pawel Oclon of Cracow University of Technology in Poland tells Euronews Green.
These include climate conditions, resource availability, and the state of energy infrastructure. Nations with existing fossil fuel systems face tougher transitions. Policy support, investment costs, and urban space also influence progress.
Experts from the Institute for European Energy and Climate Policy (IEECP) - Ivana Rogulj, Jean-Sébastien Broc, Filippos Anagnostopoulos, Tomislav Novosel, Indriany Lionggo, and Stavros Spyridakos - say the extent of district heating is another key factor.
Countries with a high share of district heating tend to have a smoother pathway toward decarbonising their heating systems. 'It is easier to replace one large gas boiler with a heat pump, biomass boiler or waste heat than to replace thousands of individual boilers with heat pumps,' they explain.

Nordic and Baltic countries dominate the top
Nordic countries, except for Norway, and the Baltic states lead Europe in the use of renewable energy for heating and cooling. All reported shares of 54 per cent or higher, more than double the EU average of 26 per cent.
Rana Adib, executive director of REN21, a global network of governments, industry experts, NGOs, and academics, explains that these nations tend to have advanced district heating systems, many of which run largely on renewable sources such as geothermal energy, waste heat or, more controversially,
biomass
.
Norway, by contrast, had a significantly lower share at 34 per cent. However, the IEECP experts suggest that Eurostat's data on Norway may be misleading.
'Renewable electricity used to drive heat pumps is not accounted for in the share for heating and cooling to avoid double counting,' according to Eurostat.

The experts point out that more than 90 per cent of Norway's electricity comes from hydropower and wind. 'The dominant source of heating in Norway is electricity,' they say.

Major Western European economies lag behind
Several Western European countries, including the EU's four largest economies, show significantly lower incorporation of renewable energy in heating and cooling.
Among them, only France (30 per cent) ranked slightly above the EU average of 26 per cent, while the rest fell below. These include Italy (22 per cent), Spain (21 per cent), Germany (17 per cent), Belgium (11 per cent) and the Netherlands (10 per cent), and
Ireland
(8 per cent).
According to Statista, renewable energy accounted for just 7.5 per cent of heating and cooling in the UK in 2018.

Adib notes that oil remains common in rural heating in Ireland, due to weak policies and minimal district heating. 'Studies have shown that 54–57 per cent of total heat demand in Ireland could be met through district heating networks, yet implementation remains limited.'
The Netherlands has long relied on natural gas and has only recently begun a major effort to phase out gas boilers, she adds.
'Belgium also relies heavily on gas and suffers from slow building renovation rates and fragmented regional policies that hinder coordinated energy action.'
She attributed the low share of renewables in Germany, France, Italy, and Spain to the widespread reliance on individual
gas boilers
. The IEECP experts further note that electric heating has been promoted in France due to the high availability of nuclear power.

Austria (39.4 per cent) represents a leading example among Central European countries in the deployment of renewable energy for heating and cooling. 'This strong performance is the result of a well-established tradition in the use of biomass - both in individual heating systems and within extensive district heating networks,' the IEECP experts say.
Most EU candidate countries reported a higher share of renewable energy use in heating and cooling compared to the EU average, with the exception of Albania (23 per cent), which fell just below. Montenegro, for instance, reached an impressive 67 per cent.
Is Europe's renewable heating progress enough?
Over the past two decades, Europe has made notable progress in increasing the share of renewables in heating and cooling - rising from around 11.7 per cent in 2004 to approximately 26.2 per cent by 2023, its highest level yet. But is this progress enough? Experts think not.
'While this growth is noteworthy, it remains insufficient,' Oclon says.

Referring to the EU's non-binding target of a 49 per cent renewable share in buildings by 2030, Adib adds: 'This pace - averaging about one percentage point every two years - is far too slow to meet the EU's climate and energy targets.'
IEECP experts emphasise the significant differences in progress among countries. 'Many countries are not currently on track to meet these obligations,' they say.
The line chart above illustrates just how much progress varies across Europe.

What policies can get European countries on track?
Prof Oclon recommends increased investment in research to enhance the efficiency of renewable energy system technologies, including photovoltaic panels, solar thermal collectors, heat pumps, and energy storage systems.

Adib of REN21 says there are several key barriers to progress, including a lack of strong policy focus on the sector, the widespread use of gas boilers, slow development of infrastructure compatible with renewables, and inconsistent or inadequate incentives.
To accelerate the deployment of renewable heating, she recommends targeted policy action focused on three key technologies: electric heat pumps, decarbonised district heating, and
solar thermal systems
- both rooftop and large-scale.
Is the EU still shifting away from Russian gas?
The EU's energy strategy is built on three core pillars: saving energy, producing clean energy and diversifying its supplies. This includes reducing dependency on Russia.
To that end, the share of pipeline gas from Russia in
EU imports
fell sharply - from more than 40 per cent in 2021 to around 8 per cent in 2023 - following the invasion of Ukraine in early 2022.

When combining pipeline gas and LNG, Russia accounted for less than 15 per cent of total EU gas imports, according to the European Commission. However, this share rose to 18.9 per cent in 2024.

UN Ocean Conference drums up signatories to key High Seas Treaty
Eighteen countries ratified the High Seas Treaty on Monday, bringing the total to 49 – just 11 short of the 60 needed for the ocean agreement to enter into force. The surge in support, occurring during the UN Ocean Conference in Nice, France, adds momentum to what could become a historic shift in how the world governs the open ocean. Here's what the treaty is, why it matters and what happens next. Formally known as the Agreement on Biodiversity Beyond National Jurisdiction, the High Seas Treaty is the first legally binding agreement focused on protecting marine biodiversity in international waters. These waters, which are beyond the jurisdiction of any single country, make up nearly two-thirds of the ocean and almost half the surface of the planet. Until now, there has been no comprehensive legal framework to create marine protected areas or enforce conservation on the high seas. Despite their remoteness, the high seas are under growing pressure from overfishing, climate change and the threat of deep-sea mining. Environmental advocates warn that without proper protections, marine ecosystems in international waters face irreversible harm. 'Until now, it has been the wild west on the high seas," said Megan Randles, global political lead for oceans at Greenpeace. "Now we have a chance to properly put protections in place.' The treaty is also essential to achieving the global '30x30' target – an international pledge to protect 30% of the planet's land and sea by 2030. The treaty creates a legal process for countries to establish marine protected areas in the high seas, including rules for destructive activities like deep-sea mining and geo-engineering. It also establishes a framework for technology-sharing, funding mechanisms and scientific collaboration among countries. Crucially, decisions under the treaty will be made multilaterally through conferences of parties (COPs) rather than by individual countries acting alone. Once 60 countries ratify the treaty, a 120-day countdown begins before it officially enters into force. That would unlock the ability to begin designating protected areas in the high seas and put oversight mechanisms into motion. As of Monday evening, 49 countries and the EU had ratified, meaning 11 more are needed to trigger that countdown. The first Conference of the Parties (COP1) must take place within one year of the treaty's entry into force. That meeting will lay the groundwork for implementation, including decisions on governance, financing and the creation of key bodies to evaluate marine protection proposals. Environmental groups are pushing to surpass the required 60 ratifications, and to do so quickly – the more countries that ratify, the stronger and more representative the treaty's implementation will be. There's also a deadline: only countries that ratify by COP1 will be eligible to vote on critical decisions that determine how the treaty will operate. 'To reach 60 ratifications would be an absolutely enormous achievement, but for the treaty to be as effective as possible, we need countries from all over the world to engage in its implementation,' said Rebecca Hubbard, director of the High Seas Alliance. 'So the next step will be to go from 60 to global.' The surge in support on Monday has raised hopes that 2025 could mark a turning point for high seas protection. 'We're on the brink of making high seas history,' Hubbard said.

Sunny Greece struggles with solar energy overload
"Letting them grow too high impairs the panel performance," the 52-year-old explains, wiping sweat from his brow. Once a centre of agricultural production, the area around Kastron Viotias, some 110 kilometres (70 miles) northwest of Athens, has seen solar parks mushroom over the past 15 years, part of a major renewable energy push in the country. Greece currently has 16 gigawatts of renewable energy installed, with solar power representing nearly 10 gigawatts, including 2.5 gigawatts that came on line last year. The rapid growth of solar is similar to other countries in Europe, where it has overtaken coal for electricity production, according to climate think tank Ember. It estimates renewables have risen to account for nearly half of the EU's electricity production. Greece did even better: 55 percent of annual consumption was covered by renewables last year, with solar accounting for around 23 percent, according to SPEF, an association which unites local solar power producers. In 2023, Prime Minister Kyriakos Mitsotakis predicted that Greece would "soon generate 80 percent of its electricity needs through renewables." But getting there is proving complicated. SPEF chairman Stelios Loumakis said that the solar sector has hit a wall because of a combination of factors, including Greece's small size, limited infrastructure and delays in building up energy storage capacity. Saturated The Greek state approved too many photovoltaic projects over the last five years and the market is saturated, leading to a "severe production surplus" on sunny days, the 56-year-old chemical engineer and energy consultant said. Greece's national grid operator in May repeatedly ordered thousands of medium-sized operators to shut down during the sunniest hours of the day to avoid overburdening the network and triggering a blackout. "The trick is to balance supply and demand. If you don't do it well, you get a blackout," said Nikos Mantzaris, a senior policy analyst and partner at the independent civil organisation Green Tank. In April, a huge blackout of unknown origin crippled the Iberian Peninsula. The Spanish government has said two major power fluctuations were recorded in the half-hour before the grid collapse, but the government insisted renewables were not to blame. "It could be something as mundane as a faulty cable," Mantzaris said. Batteries 'crucial' To manage the surplus, Greece is building battery storage capacity. But catching up to its solar electricity production will take years. "The next three years will be crucial," said Stelios Psomas, a policy advisor at HELAPCO, a trade association for Greek companies producing and installing solar panels. In the meantime, solar panel operators will have to ensure production does not outstrip capacity, thereby limiting their potential earnings. "Managing high shares of renewables -- especially solar -- requires significant flexibility and storage solutions," said Francesca Andreolli, a senior researcher at ECCO, a climate change think tank in Italy, which faces a similar problem. "Battery capacity has become a structural necessity for the electricity system, by absorbing excess renewable energy and releasing it when demand rises," she told AFP. Farm income Mimis Tsakanikas, a 51-year-old farmer in Kastron, readily admits that solar has been good to his family. The photovoltaic farm they built in 2012 at a cost of 210,000 euros clears at least 55,000 euros a year, far more than he could hope to earn by growing vegetables and watermelons. "This park sustains my home," he said. But the father of two also notes that the environmental balance has tipped in his area, with the spread of solar installations now causing concerns about the local microclimate. Tsakanikas says the area has already experienced temperature rises of up to 4.0 degrees Celsius (7.2 Fahrenheit), which he blames on the abundance of heat-absorbing solar panel parks in the area. "The microclimate has definitely changed, we haven't seen frost in two years," he told AFP. "(At this rate) in five years, we'll be cultivating bananas here, like in Crete," he said. © 2025 AFP

Italy's citizenship referendum fails due to low turnout
A referendum on easing citizenship rules and strengthening labor laws in Italy has failed due to low voter turnout, in a win for Giorgia Meloni, whose government urged people to boycott it. Over 50% of voters had to participate to validate the two-day referendum but by close of polls on Monday, June 9, just over 30% of those eligible had done so. The referendum proposal, triggered by a grassroots campaign and backed by the center-left Democratic Party (PD), would have reduced the time it takes to get citizenship. A non-EU adult resident without marriage or blood ties to Italy must currently live in the country for 10 years before they can apply – a process which can then take years more. A referendum win would have cut this to five years, putting Italy in line with Germany and France. But Prime Minister Meloni, whose far-right Brothers of Italy party has prioritized cutting irregular immigration even as her government has increased the number of migrant work visas, had said she was "absolutely against" the idea. And many members of her right-wing coalition urged people not to vote to prevent the threshold being met. The ballot included one question on citizenship. The four others were on increasing protections for workers who are dismissed, in precarious situations or involved in workplace accidents. CGIL general secretary Maurizio Landini slammed the low turnout as a sign of a "clear democratic crisis" in Italy. Under new leadership, the PD – which is polling behind Meloni's far-right Fratelli d'Italia – had sought to woo working-class voters by backing the referendum. Giovanbattista Fazzolari, Meloni's right-hand man, said the opposition "wanted to turn this referendum into a referendum on the Meloni government." "The answer seems very clear: the government emerges even stronger and the left even weaker," he told journalists in Rome. Even had it passed, the reform would not have affected a migration law many consider unfair: that children born in Italy to foreign parents cannot request nationality until they reach 18.
