The energy transition is no longer a question for the future.
In 2025, the world reached 5,149 GW of installed renewable energy capacity, after adding an extraordinary 692 GW in a single year — a 15.5% increase. Solar power accounted for approximately 511 GW of this new capacity, while wind added another 159 GW. Together, solar and wind represented 96.8% of all new renewable capacity installed during the year.
But behind these impressive figures lies a much more interesting reality: renewable energy growth is highly concentrated geographically.
Asia already accounts for around 2,891 GW of renewable capacity, roughly 56% of the global total, while Europe has around 934 GW. And within Asia, one country stands clearly above all others: China.
The question, therefore, is not simply who has the most renewable energy today.
We should also ask:
Who is growing fastest? Which countries dominate each technology? And who will be best positioned when we reach 2030?
First: What Does It Mean to Be a Renewable Energy Leader?
There are different ways to measure leadership in renewable energy.
A country may have a huge amount of installed renewable capacity because it has a very large population and electricity system.
Another may have an exceptionally high share of renewable electricity even though its absolute capacity is much smaller.
And another may be growing at a much faster rate than its competitors.
For this reason, this article will primarily use installed renewable capacity in GW, which allows us to compare the size of existing infrastructure. The figures refer to the end of 2025 and are mainly based on IRENA data.
This distinction is important:
installed GW do not directly equal electricity generated.
A solar farm, a wind turbine and a hydropower plant have very different capacity factors.
🏆 The World’s Major Renewable Energy Leaders
If we look at total installed renewable capacity, the global energy map is clearly dominated by a relatively small number of countries.
Among the largest renewable markets in 2025 were:
| Country | Approx. renewable capacity, 2025 |
|---|---|
| 🇨🇳 China | 2,258 GW |
| 🇺🇸 United States | 468 GW |
| 🇮🇳 India | 250.5 GW |
| 🇧🇷 Brazil | 228.2 GW |
| 🇩🇪 Germany | ≈200 GW |
| 🇨🇦 Canada | More than 100 GW |
| 🇯🇵 Japan | More than 100 GW |
| 🇬🇧 United Kingdom | Tens of GW |
| 🇫🇷 France | Tens of GW |
| 🇪🇸 Spain | 67.6 GW |
The figures for China, the United States, India, Brazil and Germany reveal an enormous difference in scale.
China alone has a renewable capacity comparable to that of several of the next largest markets combined.
IRENA data also show that China added around 440 GW of renewable capacity in 2025 alone.
This makes China not only the world’s largest renewable energy market, but also the main engine of global renewable expansion.
☀️ Solar Ranking: China Is in a Different League
If there is one technology completely reshaping the global energy map, it is solar photovoltaic power.
At the end of 2025, global solar PV capacity had exceeded 1,500 GW, with China accounting for approximately 1,200 GW.
The leading countries by solar PV capacity were approximately:
| Position | Country | Solar PV 2025 |
|---|---|---|
| 🥇 | 🇨🇳 China | 1,202 GW |
| 🥈 | 🇺🇸 United States | 212 GW |
| 🥉 | 🇮🇳 India | 136 GW |
| 4 | 🇩🇪 Germany | 106 GW |
| 5 | 🇯🇵 Japan | 92 GW |
| 6 | 🇧🇷 Brazil | 64.7 GW |
| 7 | 🇪🇸 Spain | 47.2 GW |
| 8 | 🇮🇹 Italy | 41.2 GW |
| 9 | 🇦🇺 Australia | 41.1 GW |
| 10 | 🇫🇷 France | 31.2 GW |
The difference between China and the rest is extraordinary.
China has approximately six times more solar capacity than the United States and almost nine times more than India.
But perhaps even more important is the speed of expansion.
In 2025, China added around 315 GW of solar PV, according to IRENA capacity data.
This is an amount that would have seemed almost unimaginable only a few years ago.
Solar power has therefore become the great engine of global renewable expansion.
🌬️ Wind Ranking: China Dominates Again
The story is repeated when we look at wind power.
At the end of 2025, global wind capacity reached approximately 1,291 GW, according to IRENA.
The leading countries were:
| Position | Country | Wind capacity 2025 |
|---|---|---|
| 🥇 | 🇨🇳 China | 640.6 GW |
| 🥈 | 🇺🇸 United States | 158.4 GW |
| 🥉 | 🇩🇪 Germany | 77.9 GW |
| 4 | 🇮🇳 India | 54.5 GW |
| 5 | 🇧🇷 Brazil | 34.9 GW |
| 6 | 🇪🇸 Spain | 33.3 GW |
| 7 | 🇬🇧 United Kingdom | 33.1 GW |
| 8 | 🇫🇷 France | 25.7 GW |
| 9 | 🇨🇦 Canada | 18.2 GW |
| 10 | 🇸🇪 Sweden | 17.4 GW |
China once again sits at an enormous distance from its competitors.
In 2025, it added approximately 119 GW of new wind capacity, close to three quarters of the total global expansion recorded by IRENA that year.
Wind power, however, differs from solar in an important way.
Solar can be deployed at almost every scale, from residential installations to enormous utility-scale projects.
Wind power depends much more heavily on suitable natural resources, grid infrastructure and, in the case of offshore wind, major investment and complex industrial supply chains.
💧 Hydropower: Here the Map Changes
Hydropower is a much more mature technology.
And when we look at this sector, China remains the leader, but other major players become much more prominent.
In 2025, China had around 382 GW of hydropower capacity, followed by:
| Position | Country | Hydropower 2025 |
|---|---|---|
| 🥇 | 🇨🇳 China | 382.1 GW |
| 🥈 | 🇧🇷 Brazil | 110.3 GW |
| 🥉 | 🇺🇸 United States | 84.2 GW |
| 4 | 🇨🇦 Canada | 84.1 GW |
| 5 | 🇷🇺 Russia | 51.8 GW |
| 6 | 🇮🇳 India | 49.1 GW |
| 7 | 🇳🇴 Norway | 34.7 GW |
| 8 | 🇹🇷 Türkiye | 32.3 GW |
| 9 | 🇯🇵 Japan | 28.3 GW |
| 10 | 🇻🇳 Vietnam | 24.7 GW |
Hydropower also has another fundamental characteristic:
it is not just electricity generation.
Hydropower plants can provide flexibility to the electricity system and, particularly when combined with pumped storage, act as enormous batteries capable of storing energy.
This will become increasingly important as solar and wind power continue to expand.
🌋 Geothermal: A Small Number of Countries, but Significant Potential
Geothermal power is much smaller on a global scale, but it has one fundamental advantage: it can generate electricity continuously and does not depend directly on sunlight or wind.
The leading geothermal countries include:
- 🇺🇸 United States
- 🇮🇩 Indonesia
- 🇵🇭 Philippines
- 🇹🇷 Türkiye
- 🇰🇪 Kenya
- 🇳🇿 New Zealand
- 🇲🇽 Mexico
- 🇮🇸 Iceland
- 🇮🇹 Italy
- 🇯🇵 Japan
At the end of 2025, global geothermal capacity was around 15.7 GW.
The United States and Indonesia remained among the major leaders, while Indonesia was one of the markets with the strongest growth.
This could become an increasingly interesting technology over the next decade.
The IEA expects annual geothermal additions to reach a record high by 2030, with the United States, Indonesia, Japan, Türkiye, Kenya and the Philippines among the key growth markets.
🌱 What About Bioenergy?
Bioenergy occupies a different position.
China, Brazil, the United States, India, Japan and several European countries have significant generation capacity based on biomass and other bioenergy resources.
Around 3.4 GW of new bioenergy capacity was added worldwide in 2025.
Japan led new additions with approximately 1.1 GW, followed by China and Brazil.
Bioenergy will not experience the explosive growth of solar, but it can play a complementary role, particularly where agricultural, forestry or industrial residues are available.
🇪🇸 Where Does Spain Stand?
And now we reach one of the most interesting parts for European readers.
Spain ended 2025 with approximately 67.6 GW of installed renewable capacity, according to IRENA.
But that figure does not fully reflect Spain’s position.
The Spanish electricity system is undergoing a very rapid transformation.
In 2025, renewables generated 55.5% of all electricity produced in Spain. Including estimated self-consumption generation, the figure rose to 56.6%.
During the same year, almost 10 GW of additional solar PV and wind capacity was installed, rising to 11.6 GW when self-consumption is included.
Spain has a particularly interesting combination:
abundant sunshine + strong wind resources + hydropower + storage + European interconnections + increasing electrification of the economy.
In solar PV, Spain is already among the world’s ten largest countries by installed capacity.
It also holds a strong position in wind power.
And there is another element that could become strategically important:
energy storage.
In 2025, pumped-storage hydropower and batteries helped integrate 9,213 GWh of energy, 6.2% more than the previous year.
🚀 But the Most Interesting Ranking Is 2030
This is where the picture changes.
Because knowing who has the most renewable capacity today is one thing.
Knowing who will add the most capacity over the next five years is something completely different.
The International Energy Agency’s current forecast is extraordinarily ambitious.
Between 2025 and 2030, around 4,600 GW of new renewable capacity could be added worldwide.
That would almost double the amount of capacity installed during the previous five-year period.
And there is one clear protagonist:
🇨🇳 China
The IEA estimates that China could account for nearly 60% of all new renewable capacity worldwide through 2030.
In other words, approximately six out of every ten new renewable GW could be installed in China.
The country is also on track to reach its solar and wind capacity targets for 2035 significantly earlier than originally planned.
🇮🇳 India: The Great Second Engine
India is emerging as another major protagonist.
The IEA expects India’s renewable capacity to increase by approximately 2.5 times between 2025 and 2030.
The country is accelerating solar PV in particular, while also expanding wind and hydropower.
India could therefore become one of the major engines of renewable growth during the next decade.
🇪🇺 Europe: Less Volume, Major Transformation
Europe cannot compete with China in terms of the absolute volume of new installations.
But its role is different.
The IEA has slightly increased its forecast for renewable growth in the European Union, driven particularly by solar PV and the expansion of corporate power purchase agreements — known as PPAs — in countries such as Germany, Spain, Italy and Poland.
Europe’s major challenge will not simply be installing more renewable capacity.
It will be integrating it.
Grids, storage, interconnections, flexibility and demand management will become increasingly important.
🇸🇦 The Middle East: The New Solar Giant
For many years, when we talked about renewable energy, we mainly thought about Europe, China or the United States.
That is changing.
The IEA has increased its forecast for renewable growth in the Middle East and North Africa by around 25%, mainly because of rapid solar expansion in countries such as Saudi Arabia.
And this creates an interesting paradox.
Some of the world’s largest oil producers are also becoming major investors in solar energy.
This does not necessarily mean that they are immediately abandoning fossil fuels.
Rather, solar power can provide abundant and increasingly competitive electricity for their economies, industries and emerging hydrogen and synthetic-fuel projects.
🇺🇸 The United States: A More Uncertain Future
The United States remains one of the world’s largest renewable energy markets.
However, the IEA has significantly reduced its renewable growth forecast for the country, by almost 50% compared with its previous estimate, due to changes in regulation, taxation and energy policy.
This demonstrates something important:
technological or industrial leadership does not automatically guarantee a particular rate of renewable deployment.
Policies, permitting, financing, grids and market conditions can radically change the outlook.
☀️ The Big Winner Will Be Solar
If there is one technology that appears almost certain to play a leading role over the next five years, it is solar PV.
The IEA estimates that approximately 80% of all new renewable capacity expected between 2025 and 2030 will be solar.
The reasons are well known:
- highly competitive costs;
- relatively fast deployment;
- scalability;
- distributed-generation potential;
- growing acceptance;
- and enormous opportunities for integration with batteries.
Solar is no longer simply another renewable technology.
It is becoming one of the fundamental building blocks of the global electricity system.
🌬️ Wind Will Keep Growing — But With More Challenges
Wind power will also continue to expand strongly.
The IEA expects global wind capacity to approach 2,000 GW by 2030.
However, the sector faces challenges that are somewhat different from those of solar:
- higher financing costs;
- supply-chain constraints;
- permitting;
- raw-material costs;
- financial difficulties affecting some manufacturers;
- and particularly significant challenges in certain offshore-wind markets.
The IEA expects around 140 GW of additional offshore wind capacity between 2025 and 2030, but has reduced its previous forecast by 27% because of economic and regulatory difficulties.
🔋 And Here Comes the Real Challenge: Storage and Integration
Renewable-capacity rankings tell only part of the story.
We can install thousands of GW of solar and wind.
But we then have to ensure that the electricity reaches consumers when it is needed.
This is where batteries come in.
Pumped-storage hydropower.
Smart grids.
Demand-side management.
Cross-border interconnections.
Electric vehicles.
Hydrogen.
And new long-duration energy-storage technologies.
The IEA itself highlights grid integration, financing and supply-chain constraints among the main obstacles that could limit the expected pace of renewable growth.
This means that the next major energy competition will not simply be about installing more solar panels or wind turbines.
It will be about building the system capable of using them efficiently.
🌍 The Renewable World of 2030 Will Look Very Different
If current forecasts become reality, by 2030 we will have an energy system in which:
China will remain the global center of renewable expansion.
India will become one of the main growth engines.
Europe will move towards an increasingly electrified and renewable electricity system.
The United States will remain a fundamental player, although its trajectory will depend heavily on energy policy.
The Middle East will become one of the world’s new major solar markets.
And countries such as Spain, Australia, Brazil, Canada, Chile, Morocco and South Africa will have major opportunities thanks to their solar, wind or hydropower resources.
The geography of energy is changing.
🧭 So, Who Is Really Leading?
The answer depends on what we mean by leadership.
If we are talking about total installed capacity, China is clearly ahead.
If we are talking about solar, China dominates by a huge margin.
If we are talking about wind, China is again in first place.
In hydropower, China leads once again, followed by Brazil and the United States.
In geothermal, the spotlight moves towards the United States, Indonesia and the Philippines.
And if we are talking about future growth, China and India emerge as two of the major protagonists, while Europe, the Middle East and other emerging markets will also gain importance.
But there is a much more important conclusion.
The Real Ranking Will Be About Energy Systems
By 2030, it will no longer be enough to ask:
“How many GW of renewable capacity does this country have?”
We will need to ask:
- How much renewable electricity can it actually generate?
- How much storage capacity does it have?
- How strong are its electricity grids?
- Can it transport electricity from generation centers to areas of demand?
- Can it manage millions of electric vehicles?
- Can it integrate data centers and electrified industry?
- Does it have sufficient interconnection capacity?
- Can it use surplus electricity to produce hydrogen or other fuels?
- Can it finance further investment?
Because the future energy system will not be determined simply by who installs the most capacity.
It will be determined by who can turn that installed capacity into a flexible, reliable and competitive electricity system.
Conclusion: The Renewable Race Has Only Just Begun
The 2025 figures leave little doubt about the direction of the global energy market.
The world added 692 GW of new renewable capacity in a single year, reaching 5,149 GW in total. Solar accounted for approximately three quarters of new capacity, while wind provided most of the remaining growth.
But perhaps the most important numbers are those that lie ahead.
The IEA expects another 4,600 GW of renewable capacity to be added between 2025 and 2030.
That is an extraordinary figure.
And behind these numbers lies a much deeper transformation.
We are moving from an energy system based largely on large centralized power plants and fossil fuels towards one that is increasingly distributed, digitalized and dependent on variable renewable resources.
Solar panels and wind turbines are only one part of this transformation.
Then come batteries.
The grids.
Pumped-storage hydropower.
Electric vehicles.
Data centers.
Demand management.
Hydrogen.
And millions of consumers who may increasingly become both producers and managers of energy.
Perhaps, in a few years, we will stop talking about “the countries with the most renewable energy.”
And we will start talking about “the countries with the smartest energy systems.”
The race is no longer simply about installing more gigawatts.
It is about learning how to use them.
And in that race, the world has only just begun to move.
