Denmark, home to leading wind turbine manufacturers Vestas and Siemens Gamesa, is a pioneer in wind energy with significant offshore wind farms.

Introduction

Wind energy is a rapidly growing source of renewable energy, contributing significantly to the global shift towards sustainable energy solutions. Among the various countries harnessing wind power, a few stand out for their exceptional wind turbine technology and infrastructure. This article explores which country has the best wind turbines, considering factors such as technology, efficiency, and overall contribution to the wind energy sector.

The world is standing at a crossroads. On one side, we have the traditional fossil fuels that powered our industries for centuries but left behind a trail of carbon emissions, climate change, and resource dependency. On the other side, we have renewable energy—clean, sustainable, and future-focused. Among all renewable sources, wind energy has emerged as one of the most promising solutions.

But here’s the interesting part: not all wind turbines are created equal. Just like smartphones differ in performance, design, and reliability, wind turbines vary depending on where they’re built and who builds them. This leads us to an important question—which country has the best wind turbines?

This isn’t just a casual debate. The answer matters for energy security, climate change solutions, and even global economics. Countries are competing fiercely to design, manufacture, and install the most efficient and powerful turbines. From Denmark’s pioneering designs to China’s massive production capacity, the global race is heating up.

In this article, we’ll take a closer look at wind energy’s importance, the criteria for defining “the best,” and how leading nations stack up against each other. By the end, you’ll have a clear picture of which country truly leads the way in wind turbine technology—and why it matters for our future.

Why Wind Turbines Matter Today

Wind turbines are more than just tall structures with spinning blades on the horizon—they represent a shift in how the world thinks about energy. At a time when climate change, rising fuel costs, and energy insecurity dominate global discussions, wind turbines have become a symbol of hope and progress.

First, they provide clean energy without harmful emissions. Unlike coal or natural gas plants, wind turbines don’t release carbon dioxide or toxic pollutants into the air. Each turbine quietly generates electricity by harnessing a natural resource that’s free and abundant—the wind. This makes them one of the most eco-friendly solutions available today.

Second, they reduce dependency on fossil fuels. Many countries still rely heavily on oil and gas imports, making them vulnerable to political conflicts and price fluctuations. Wind power offers an alternative that’s produced locally, giving nations greater energy independence and stability.

Third, wind turbines are cost-effective in the long run. While the upfront investment is high, once installed, turbines have very low operating costs. Over time, they can deliver some of the cheapest electricity available, especially in regions with strong and steady winds.

Finally, they represent innovation and the future of energy. Wind turbines today are not just machines—they’re equipped with sensors, AI systems, and advanced materials. This technology is constantly evolving, making turbines more powerful, more efficient, and more reliable every year.

In short, wind turbines matter today because they address three urgent global needs at once: fighting climate change, securing energy independence, and ensuring affordable electricity for the future. They aren’t just part of the solution—they’re at the heart of it.

The Global Race in Renewable Energy

The push for renewable energy isn’t just about going green—it’s about global leadership, economic growth, and survival in a rapidly changing world. Every major nation now sees renewable energy as both a necessity and a competition. And at the centre of this race are wind turbines, one of the fastest-growing sources of clean power.

Countries are no longer asking if they should invest in renewables, but how fast they can do it. The urgency comes from multiple fronts: rising global temperatures, international climate agreements like the Paris Accord, and the need for energy independence in an uncertain geopolitical landscape. Renewable energy has become the new battlefield for innovation and influence.

In this race, Europe has long been the frontrunner. Nations like Denmark, Germany, and Spain pioneered wind technology decades ago, turning themselves into hubs of expertise and reliability. Their companies set the standards that the rest of the world tries to follow.

But now, Asia is charging ahead, with China taking the lead. By scaling up production and building massive wind farms, China has become the world’s largest manufacturer and installer of wind turbines. India is also emerging as a strong competitor, focusing on affordable solutions for developing markets.

Meanwhile, the United States is betting on size and innovation, with projects like the Haliade-X turbine and massive wind farms across Texas and the Midwest. For America, it’s not only about sustainability but also about maintaining technological dominance.

This global race is more than just numbers—it’s about shaping the future energy map. Whoever masters wind technology gains a strategic edge, not only in tackling climate change but also in strengthening their economy, creating jobs, and influencing global policy.

Renewable energy is today’s version of the space race, and wind turbines are the rockets propelling countries toward leadership in a clean-energy future.

What Are Wind Turbines?

At their core, wind turbines are machines designed to capture the natural movement of air and transform it into electricity. They may look like giant fans standing tall in fields or off the coast, but instead of consuming electricity, they generate it.

A wind turbine works on a simple principle: the wind turns the blades, which spin a shaft connected to a generator, producing clean power. The idea is almost poetic—taking something as invisible and endless as the wind and turning it into energy we can use to power homes, schools, businesses, and entire cities.

Think of it like a bicycle dynamo light. When you pedal, the wheel spins a small generator that powers the light. Wind turbines work on the same principle, just on a massive scale—where instead of your legs, it’s the wind doing the pedalling.

Modern turbines come in different shapes and sizes, but most are the familiar three-blade horizontal-axis turbines. These blades can be longer than a football field, sweeping through the air to catch as much wind as possible. Offshore turbines are even larger, designed to harness the stronger, steadier winds over the ocean.

There are also vertical-axis turbines, less common but useful in urban environments where wind direction changes frequently. While they’re not as efficient as the big horizontal ones, they show how adaptable wind technology can be.

What makes wind turbines so important is that they generate electricity without burning fuel, releasing smoke, or creating waste. They quietly produce power from a resource that’s free, renewable, and available almost everywhere on Earth.

Wind turbines are more than machines—they are one of humanity’s smartest tools for balancing progress with responsibility, blending engineering with nature to secure a cleaner future.

Simple Definition

A wind turbine is a device that converts the natural movement of wind into usable electricity. In the simplest terms, it’s like a giant fan—but instead of using electricity to make blades spin, it uses the spinning blades to create electricity.

Here’s how it works: when the wind blows, it pushes against the blades of the turbine, causing them to rotate. This rotation turns a shaft connected to a generator inside the turbine’s body. The generator then produces electrical energy, which can be sent through power lines to homes, businesses, and industries.

So, if we break it down, a wind turbine does three main things:

  1. Catches the wind using its blades.
  2. Converts movement into mechanical energy through the spinning shaft.
  3. Generates electricity using a generator.
  4. A wind turbine is just a smart way of turning moving air into clean, renewable power we can actually use every day.

Role in Clean Energy Production

Wind turbines play a central role in the world’s transition to clean energy. Their main job is simple yet powerful—to generate electricity without relying on fossil fuels. Unlike coal, oil, or natural gas, which release harmful greenhouse gases when burned, wind turbines harness a natural resource that’s endlessly available and completely emission-free.

Here’s why their role is so important:

  1. Zero carbon emissions – Every unit of electricity produced by a wind turbine helps cut down on the need for energy from coal or gas plants. This directly reduces carbon dioxide in the atmosphere, slowing down climate change.
  2. Sustainable power generation – Wind will never run out. As long as the Earth’s atmosphere exists, winds will blow. That makes wind turbines a reliable long-term solution for global energy needs.
  3. Cleaner air and healthier communities – Unlike fossil fuel plants that release smoke, soot, and harmful gases, wind turbines produce energy without polluting the air. This means cleaner skies, healthier lungs, and reduced health costs.
  4. Supporting renewable energy grids – Wind energy is often combined with solar, hydro, and other renewable sources to create a balanced energy system. Turbines provide power during windy conditions, helping to stabilise the electricity supply.

To put it simply, wind turbines act as guardians of the planet, generating electricity while protecting the environment. They bridge the gap between energy demand and environmental responsibility, proving that progress doesn’t have to come at the expense of nature.

Why Wind Energy Is Important

Wind energy has become one of the cornerstones of the global shift toward renewable power. It’s not just about spinning blades on the horizon—it’s about building a cleaner, safer, and more sustainable future. Here’s why wind energy is so crucial today:

  1. Reducing Carbon Emissions

The fight against climate change depends heavily on reducing greenhouse gas emissions, and wind energy plays a major role. Every megawatt of electricity produced by wind replaces electricity that might otherwise come from coal or gas plants. This prevents tons of carbon dioxide from entering the atmosphere. In fact, wind farms worldwide help avoid billions of tons of emissions each year, making them a direct weapon in the battle against global warming.

  1. Energy Independence

Relying on imported fossil fuels can make countries vulnerable to price spikes and political instability. Wind energy changes that. By installing wind farms, nations can generate electricity from their own natural resources. This not only boosts energy security but also keeps money within the local economy instead of paying for foreign oil and gas.

  1. Long-Term Sustainability

Unlike fossil fuels, which are finite and depleting, wind is endless. As long as the sun shines and the Earth rotates, winds will continue to blow. This makes wind energy one of the most sustainable power sources available. Investing in wind is like planting seeds for an energy source that will keep giving for generations.

  1. Economic Growth and Jobs

The wind energy sector is also a major employer. From designing and manufacturing turbines to installing and maintaining them, millions of jobs are created worldwide. Communities near wind farms also benefit through local investments, tax revenues, and infrastructure improvements.

  1. Affordable Electricity Over Time

While building wind turbines requires upfront investment, the long-term costs are low. Wind is free, and turbines can produce electricity for decades with minimal maintenance. In many regions, wind energy is now one of the cheapest sources of new electricity, even beating fossil fuels in cost.

Wind energy is important because it tackles climate change, strengthens energy security, promotes sustainability, creates jobs, and delivers affordable power. It’s not just an option anymore—it’s a necessity for a cleaner and more resilient future.

Reducing Carbon Emissions

One of the biggest reasons wind energy is so important is its ability to cut down carbon emissions. Unlike coal, oil, or natural gas power plants, which burn fuel and release carbon dioxide (CO₂) into the atmosphere, wind turbines produce electricity without creating any greenhouse gases. They simply use the natural force of the wind to spin blades and generate clean power.

Why does this matter so much? CO₂ is the main driver of global warming. The more fossil fuels we burn, the more heat gets trapped in Earth’s atmosphere, leading to rising temperatures, melting ice caps, extreme weather, and shifting climates. Wind turbines directly reduce this problem by replacing polluting power plants with emission-free electricity.

To put things into perspective:

  • A single large wind turbine can prevent over 5,000 tons of CO₂ emissions per year—the equivalent of taking more than 1,000 cars off the road.
  • Wind farms worldwide already help prevent billions of tons of emissions annually, making them one of the strongest tools we have in fighting climate change.

Beyond reducing CO₂, wind turbines also avoid other harmful byproducts of fossil fuels, such as sulfur dioxide (which causes acid rain) and nitrogen oxides (which contribute to smog). This means cleaner skies, healthier ecosystems, and safer communities.

Every spin of a wind turbine blade is a step toward a cooler, cleaner, and healthier planet. By reducing carbon emissions, wind energy doesn’t just generate electricity—it helps secure the future of life on Earth.

Energy Independence

Energy independence means a country can produce enough of its own energy without relying heavily on imports of oil, coal, or natural gas from other nations. Wind energy plays a massive role in making this possible.

For decades, many countries have depended on fossil fuel imports to keep their lights on and industries running. But this dependency comes with risks. Political conflicts, trade disputes, or sudden price hikes in the global market can leave nations vulnerable and struggling to afford energy. Wind power offers a way out of this trap.

By harnessing their own natural wind resources, countries can generate electricity locally. This reduces the need for foreign fuel and keeps energy costs more stable. For example, Denmark and Germany, two leaders in wind energy, have significantly reduced their reliance on imported fossil fuels by investing heavily in wind farms.

Wind energy also strengthens national security. When a country isn’t dependent on unstable foreign suppliers, it has more control over its own future. Local communities benefit too, since building and maintaining turbines creates jobs and keeps money circulating within the domestic economy rather than sending it overseas.

Wind energy empowers nations to stand on their own. Instead of being at the mercy of global fuel markets, they can tap into a free and renewable local resource—the wind. This makes energy not only cleaner but also more secure and reliable for generations to come.

Long-Term Sustainability

One of the greatest strengths of wind energy is its long-term sustainability. Unlike fossil fuels—coal, oil, and natural gas—that are finite and will eventually run out, wind is a renewable resource. As long as the Earth rotates and the sun heats the atmosphere, winds will continue to blow. This makes wind power a never-ending source of clean electricity.

But sustainability isn’t just about availability—it’s also about environmental responsibility. Wind turbines don’t deplete natural resources or cause permanent damage to ecosystems. Once installed, they generate electricity for decades with very little impact on the environment compared to mining coal or drilling for oil.

Another key aspect is future readiness. Fossil fuels become harder and more expensive to extract over time, while wind energy only gets cheaper as technology improves. Turbines today are larger, more efficient, and capable of producing more power than ever before. This means wind energy will remain a competitive and sustainable option for decades to come.

From an economic perspective, sustainability also means predictable costs. Since wind is free, the cost of producing electricity from turbines doesn’t fluctuate wildly like oil and gas prices do. This provides stable and affordable energy for households, industries, and governments in the long run.

Wind energy isn’t just a short-term solution—it’s a future-proof investment. By relying on a resource that never runs out and grows cheaper with innovation, wind power ensures that humanity can meet its energy needs today without compromising tomorrow’s resources or environment.

The Global Wind Energy Market

Global Statistics and Growth Trends

Wind energy has transformed from a small-scale experiment into one of the fastest-growing energy industries worldwide. The statistics are not only impressive but also tell the story of how countries are racing toward a cleaner, more sustainable future.

  1. Explosive Growth in Capacity

Over the past two decades, global wind capacity has skyrocketed. In the early 2000s, installed wind power was under 20 gigawatts (GW) worldwide. Fast forward to today, and the figure has surged past 900 GW, with experts predicting it will double by 2035. This makes wind energy one of the leading sources of new electricity generation globally.

  1. Onshore Dominance, Offshore Rising

Currently, onshore wind farms make up the majority of global capacity. They are easier and cheaper to build, making them the backbone of wind energy in countries like China, the U.S., and India. But the real game-changer is offshore wind. Europe leads the way, with the UK and Denmark hosting massive offshore projects, while China has recently overtaken Europe in total offshore capacity. Offshore wind is expected to grow more than sixfold by 2040, thanks to stronger winds and new floating turbine technology.

  1. Regional Leaders

  • North America: The U.S. is the main player, especially in onshore wind across the Midwest and Texas.
  • Europe: Germany, Spain, and Denmark remain at the forefront of engineering and offshore projects.
  • Latin America & Africa: Emerging markets like Brazil, Mexico, and South Africa are showing strong growth potential.
  1. Falling Costs Driving Growth

One of the biggest reasons for this boom is cost. In many regions, wind power is now cheaper than coal or natural gas. The levelized cost of energy (LCOE) for wind has dropped by over 60% in the past decade, making it one of the most affordable sources of new electricity.

  1. Employment and Economic Impact

The wind sector is also a job creator. Globally, more than 1.3 million people are employed in wind energy, from manufacturing to maintenance. As more projects come online, that number will keep growing, boosting both local and global economies.

  1. Future Trends

Looking forward, several trends stand out:

  • Bigger turbines with longer blades to capture more energy.
  • Floating offshore wind farms, opening new ocean areas for development.
  • Hybrid renewable projects, combining wind with solar or storage.
  • Stronger government targets for net-zero emissions, which will keep pushing demand upward.

In short, the global statistics show a clear direction: wind energy isn’t just a part of the future—it’s already here, reshaping economies and power systems worldwide. And with growth trends pointing upward, it’s only set to become more dominant in the decades ahead.

Criteria for the Best Wind Turbines

When people ask, “Which country has the best wind turbines?”, the answer isn’t as simple as pointing to one nation. To figure it out, we need to look at what makes a wind turbine truly the best. Just like choosing a car involves more than speed—you think about safety, durability, fuel efficiency, and cost—the same goes for wind turbines.

Here are the key criteria that separate good turbines from the very best:

  1. Efficiency and Performance

The most important measure of a wind turbine is how much electricity it can generate from the wind available. This depends on blade design, height, and technology. The more efficient a turbine is, the more power it produces—even at lower wind speeds. High-efficiency turbines are especially valuable in areas where winds aren’t always strong.

  1. Durability and Reliability

A wind turbine is a long-term investment, expected to run for 20–25 years. The best turbines are built to withstand tough conditions—whether that’s salty sea air in offshore farms, scorching desert heat, or freezing mountain winds. Reliability also matters; downtime means lost energy and lost money, so the best turbines are those that keep spinning with minimal maintenance.

  1. Cost-Effectiveness

It’s not just about building a powerful turbine—it’s about building one that makes financial sense. The cost includes manufacturing, transporting, installing, and maintaining the turbine. The best turbines strike a balance between performance and affordability, offering maximum electricity at the lowest lifetime cost.

  1. Environmental Adaptability

Not all environments are the same. Some turbines need to work in shallow waters offshore, while others stand tall in open plains or crowded cities. The best turbines are adaptable, with designs that can fit different landscapes and weather conditions. For example, offshore turbines need to be massive and resistant to storms, while urban turbines may need compact designs to fit smaller spaces.

  1. Innovation and Technology Integration

Today’s top turbines use smart technology—sensors, AI, and real-time monitoring systems that predict weather changes and adjust blade angles for maximum efficiency. Some even connect directly to smart grids for smoother electricity distribution. Innovation is what keeps turbines improving year after year.

The best wind turbines are not just the biggest or the most powerful. They are the ones that combine efficiency, durability, affordability, adaptability, and innovation into a single package. This is why different countries shine in different areas—Denmark in offshore leadership, Germany in engineering, China in large-scale production, and the U.S. in innovation.

Efficiency and Performance

When it comes to wind turbines, efficiency and performance are the heart of the game. A turbine’s main job is to take the natural movement of the wind and convert it into as much electricity as possible. The better it does this, the more valuable it becomes.

  1. Capacity Factor – The Real Measure of Efficiency

The capacity factor is a key metric. It shows how much electricity a turbine actually produces compared to its maximum potential. For example, if a turbine could generate 100% of its rated capacity but only produces 40% on average, its capacity factor is 40%. The best modern turbines are reaching capacity factors above 50%, rivaling traditional power plants.

  1. Blade Design and Aerodynamics

A turbine’s blades are like the wings of an airplane—they’re carefully shaped to capture as much wind energy as possible. Longer, lighter, and smarter blades can sweep a larger area, catching more wind and improving overall performance. Some of today’s blades are longer than a football field, maximizing efficiency even in low-wind conditions.

  1. Height Matters

The taller the turbine, the stronger and more consistent the wind. That’s why modern turbines are built higher than ever before—often over 100 meters tall. By reaching these stronger winds, turbines can produce more energy and increase efficiency.

  1. Smart Control Systems

Efficiency isn’t just about hardware—it’s also about brains. Many turbines now use AI and advanced sensors to adjust the pitch (angle) of the blades and yaw (direction facing the wind) in real time. This ensures that the turbine captures the maximum possible energy, no matter how wind conditions change.

  1. Performance in Different Wind Speeds

The best turbines don’t just work well in strong winds—they also perform efficiently in low to medium winds. This is crucial because not every region has hurricane-level gusts. High-performance turbines are designed to produce steady electricity across a wide range of conditions.

A turbine’s efficiency and performance determine how much clean power we get for the money invested. Countries leading in wind technology are constantly pushing these boundaries—designing turbines that are taller, smarter, and more powerful than ever before.

Durability and Technology

A great wind turbine isn’t just powerful—it’s built to last. Durability and technology go hand in hand, ensuring turbines can operate for decades under some of the harshest conditions on Earth.

  1. Withstanding Harsh Environments

Wind turbines face everything nature throws at them—scorching sun, freezing winters, salty ocean air, heavy rains, and even storms. The best turbines are engineered with corrosion-resistant materials, reinforced towers, and advanced coatings to handle these extremes. Offshore turbines, in particular, must be exceptionally durable since maintenance at sea is costly and difficult.

  1. Long Operational Lifespan

A standard wind turbine is designed to last around 20–25 years, but technology is pushing that even further. Stronger materials like carbon fiber in blades and advanced alloys in towers extend their life span while reducing wear and tear. A longer-lasting turbine means a better return on investment and more sustainable energy over time.

  1. Smart Maintenance with Technology

Durability isn’t just about physical strength—it’s also about predictive technology. Modern turbines are equipped with sensors that constantly monitor vibration, temperature, and stress levels. Using AI and data analytics, operators can predict issues before they become serious, allowing for preventive maintenance instead of costly emergency repairs.

  1. Self-Adjusting Systems

Advanced turbines use automated control systems that adjust blade pitch and yaw in real-time to reduce mechanical strain. By facing the wind in the most efficient way and adjusting to sudden gusts, these systems protect the turbine from unnecessary damage while improving energy output.

  1. Resilience Against Natural Disasters

Some of the newest turbines are designed to withstand hurricanes and typhoons, especially in regions like Asia where extreme weather is common. This resilience makes them far more reliable in places where older designs would have failed.

In essence, durability and technology ensure that turbines don’t just produce energy today but keep generating clean power year after year, with minimal downtime. The best turbines combine tough engineering with smart technology to maximize reliability, even in the most demanding environments.

Cost-Effectiveness

When deciding which wind turbines are truly the best, cost-effectiveness is a deal-breaker. It’s not just about how powerful or advanced a turbine is—it’s about whether it delivers the most electricity for the lowest overall cost during its lifetime.

  1. Upfront Investment vs. Long-Term Savings

Building a wind turbine is expensive at the start. The blades, tower, generator, and installation require significant investment. However, once it’s up and running, the fuel—wind itself—is completely free. Over 20–25 years of operation, a well-designed turbine produces electricity at a fraction of the cost of fossil fuels.

  1. Levelized Cost of Energy (LCOE)

The industry often uses LCOE to measure cost-effectiveness. This includes the total cost of building, maintaining, and operating the turbine, divided by the amount of electricity it produces over its lifetime. The best turbines are those that achieve a low LCOE, making them cheaper than coal, oil, or even natural gas. In fact, in many regions, wind power has already become the cheapest source of new electricity.

  1. Maintenance and Operating Costs

Durable turbines save money because they need fewer repairs. Thanks to predictive maintenance technology, operators can fix small problems before they become expensive breakdowns. This reduces downtime, keeps the turbines spinning, and ensures consistent electricity flow—all while keeping costs low.

  1. Scale and Mass Production

Countries like China have achieved cost-effectiveness by producing turbines at massive scale. The more turbines are manufactured and installed, the cheaper each unit becomes. Similarly, offshore wind projects are becoming more cost-competitive as technology and supply chains improve.

  1. Community and Grid Benefits

Cost-effectiveness isn’t just about the turbines themselves. Wind projects often provide local economic benefits—from job creation to tax revenues—that make them even more valuable for communities. Plus, once connected to the grid, they help stabilize electricity prices, protecting consumers from fossil fuel price spikes.

Cost-effectiveness is about balancing performance with affordability. The best turbines don’t just generate a lot of power—they do it in a way that makes renewable energy accessible, competitive, and sustainable for the long run.

Environmental Adaptability

Not all wind turbines are built for the same conditions. What works perfectly in the flat, windy plains of Texas may not work in the salty, stormy waters of the North Sea or the crowded rooftops of a city. This is where environmental adaptability becomes a crucial measure of what makes the best wind turbines.

  1. Onshore vs. Offshore Challenges
  • Onshore turbines are often built on farmland, deserts, or mountain ridges. They need to be efficient at different altitudes, temperatures, and wind speeds.
  • Offshore turbines, by contrast, face constant salt spray, corrosion, and extreme storms. The best offshore designs use stronger materials, floating foundations, and storm- resistant engineering to survive for decades in these harsh environments.

2. Performance in Low-Wind Regions

Not every country has strong, steady winds. That’s why the best turbines are designed to perform even in low-to-medium wind conditions. By using longer blades and advanced aerodynamics, they can generate power where older models would barely turn. This adaptability opens up wind energy to more parts of the world.

  1. Urban and Remote Applications

Some turbines are designed to fit urban environments, where wind directions change quickly and space is limited. Vertical-axis turbines, for example, can be used in cities because they don’t need to face the wind directly. Meanwhile, in remote areas with no grid access, smaller modular turbines provide clean energy for villages, farms, or islands.

  1. Climate Resilience

The best turbines are engineered to handle extreme weather—whether that’s freezing winters in Canada, typhoons in Asia, or scorching deserts in the Middle East. Turbines in these regions use special coatings, heating systems for blades, or reinforced structures to adapt to local challenges.

  1. Land and Wildlife Considerations

Adaptability also means being environmentally responsible. Turbines can be placed in ways that minimize disruption to wildlife, avoid sensitive habitats, and coexist with farmland. In fact, many farmers lease land for wind turbines without losing the ability to grow crops or raise livestock.

In short, environmental adaptability ensures that wind turbines aren’t just powerful in one setting—they can be customized to work anywhere in the world, from icy oceans to busy cities. This flexibility makes wind power a truly global solution.
