Record Renewable Growth Signals a Turning Point

Renewable energy expansion has never been faster. In 2024 alone, global renewable power capacity grew by 585 gigawatts (GW), a 15% jump that brought the world’s total installed renewables to about 4.45 terawatts. This was the largest annual increase ever, accounting for over 90% of all new power capacity worldwide. Solar photovoltaics led the charge, adding an astounding 450+ GW in a single year, with wind power contributing most of the remainder. This boom in clean energy continued into 2025. In the first half of the year, wind and solar installations surged so rapidly that renewable sources generated 5,072 terawatt-hours of electricity, slightly more than coal’s 4,896 TWh over the same period, a historic first. Renewables provided about 34.3% of global electricity, edging above coal’s 33.1% share. In other words, for the first time on record, clean power out-produced the world’s dirtiest fuel over a significant period.

This milestone illustrates the accelerating trajectory of the energy transition. Solar power has more than doubled its contribution to world electricity in just four years, rising from 3.8% of generation in 2021 to roughly 8.8% by mid-2025. Together, solar and wind are growing fast enough to cover all new demand for power and even begin displacing existing fossil generation. In the first half of 2025, a 2.6% rise in global electricity consumption was met entirely by increased output from solar and wind, which grew by a combined 403 TWh and offset a small decline in total fossil fuel generation. “We are seeing the first signs of a crucial turning point,” one senior energy analyst observed, noting that renewables are now expanding fast enough to keep up with the world’s growing appetite for electricity. These trends mark the beginning of a new era in which clean power can reliably meet incremental energy needs, a fundamental requirement for phasing out carbon-intensive sources.

Underlying these headline numbers are the extraordinary scale and speed of renewable deployments across key regions. China alone installed about 360 GW of new wind and solar capacity in 2024, more than half of the global additions that year. This massive build-out helped drive an inflection point in China’s emissions: for the first time, growth in clean electricity outpaced demand growth, causing China’s energy-related CO₂ emissions to fall by 1.6% year-on-year in early 2025. Analysts note that electricity from new wind, solar, and nuclear plants was sufficient to cut coal-fired output even as China’s power demand surged. The result is that China’s emissions have stabilized or declined for over a year, a potential peak in the world’s largest emitter if the trend holds. This development underscores how rapid clean energy expansion can bend the emissions curve even in fast-growing economies. Other regions are also scaling up: India, the Middle East, Europe, and North America all saw record renewable installations recently, contributing to the global tipping point in the electricity mix. More than ever before, clean energy growth is a worldwide phenomenon, not limited to a few front-runner countries.

Cost Competitiveness and Policy Catalysts Fueling the Boom

Driving this remarkable momentum is a convergence of economic and policy factors that have matured over the past decade. On the economics side, renewable technologies have achieved cost parity, or better, with fossil fuels in most markets, fundamentally altering investment incentives. According to the International Renewable Energy Agency (IRENA), 91% of new utility-scale renewable projects commissioned in 2024 offered cheaper electricity than the most affordable fossil-fuel alternative. Solar photovoltaic power, for example, was about 41% lower in cost on average than equivalent generation from natural gas or coal, while onshore wind power was 53% cheaper than the lowest-cost fossil option. This cost revolution has been enabled by technological advances, economies of scale, and learning-curve effects, from more efficient solar modules to larger and more efficient wind turbines. Battery storage costs have also plummeted (over 90% decline in the past decade), improving the value proposition of renewables by enabling grid stability and round-the-clock clean power. The result is that in many regions today, it is simply more profitable and logical to build new solar or wind farms than to operate existing coal plants, let alone invest in new fossil capacity. Clean energy is no longer a niche or a subsidy-dependent choice; it is often the most cost-effective source of energy available.

Equally important has been a wave of supportive policies and investment signals from governments and industries worldwide. Over the past few years, major economies have enacted sweeping climate and energy legislation that turbocharged clean tech deployment. For instance, the United States’ Inflation Reduction Act of 2022 unleashed hundreds of billions of dollars in clean energy incentives, spurring a manufacturing and investment boom in renewables, batteries, and electric vehicles across the U.S. and beyond. The European Union, through its Green Deal and RePowerEU plans, set ambitious renewable targets (such as 45% of energy from renewables by 2030) and tightened emissions regulations, forcing utilities and automakers onto a greener path. China’s central government mandated aggressive renewable expansion in its five-year plans and funneled substantial public and private capital into solar, wind, and grid upgrades, evident in China’s world-leading installation figures. Similar policy moves in India, Japan, South Korea, and other countries have further tilted the scales. These actions have given investors confidence that demand for clean technologies will continue rising, creating a virtuous cycle of greater investment and further cost declines.

The capital flows tell the story. Annual global investment in the energy transition hit a new high, exceeding $2 trillion in the past year, roughly double the level in 2020. For the first time, spending on clean energy (renewables, electric transport, efficiency, and more) is outpacing fossil fuel investments by a significant margin. Crucially, the private sector is now providing the lion’s share of this finance: about three-quarters of global clean energy investment is coming from private companies and investors, not governments. Businesses clearly see profit and growth opportunities in clean energy, from utilities shifting their portfolios to technology firms and automakers electrifying their products. “New renewable power out-competes fossil fuels on cost, offering a clear path to affordable, secure, and sustainable energy,” IRENA’s Director-General Francesco La Camera noted, emphasizing that renewables today are both a climate solution and “the biggest economic opportunity of our time.” In short, market economics and policy priorities are now aligned in favor of clean energy to an unprecedented degree. This alignment is a key reason the transition is hitting a tipping point: the fundamental drivers of the global energy system have swung toward low-carbon options, which makes the current growth trajectory more likely to continue.

Challenges: Emissions, Investment Gaps, and Infrastructure Bottlenecks

For all the extraordinary progress, this tipping point remains delicate. A stark reminder of the work ahead is the fact that global carbon emissions from the energy sector are still rising, and hit a record high in 2024. Despite the surge in renewables, energy-related CO₂ emissions reached 37.8 billion tonnes in 2024, an all-time peak. This is because total energy demand continues to grow and much of the world’s existing energy infrastructure is still fossil-fueled. Indeed, as of today around 80% of global primary energy consumption is supplied by fossil fuels, a proportion virtually unchanged from 30 years ago. The sobering reality is that the clean energy build-out, as rapid as it is, has not yet cut into the absolute dominance of coal, oil, and natural gas in the world’s energy mix. Emissions are beginning to plateau in some regions (as seen in China or in the electricity sector globally), but they have not yet begun the sustained decline needed to achieve international climate goals. The current momentum could stall without continued acceleration, a point underscored by the International Energy Agency’s warning that, under today’s policies, demand for oil, gas, and coal is still far too high to limit warming to 1.5°C. In other words, passing a tipping point in clean energy growth is not the same as winning the climate battle; it is a critical step, but much more scaling up is required to actually reduce emissions at the necessary pace.

One major challenge is the investment gap relative to what climate scenarios say is needed. While $2 trillion per year going into clean energy is remarkable, leading analyses indicate this must at least triple to around $5–6 trillion annually by 2030 in order to stay on track for climate targets. The current rate of renewable deployment, though record-setting, is still insufficient to meet the goal agreed at the 2023 COP28 summit of tripling global renewable capacity by 2030. At the end of 2024, cumulative renewables were about 4.4 TW; hitting the 11.2 TW target by 2030 would require adding over 1,100 GW every year from 2025 onward, nearly double the 2024 addition. Similarly, energy efficiency improvements need to accelerate dramatically (global energy intensity improved just 1% last year versus the 4% annual gains needed). Closing these gaps will demand much higher capital mobilization, especially in emerging markets. Currently, the majority of clean energy investment is concentrated in advanced economies and China, whereas developing countries, which are expected to drive 80% of future energy demand growth, receive only a fraction of the financing. This imbalance not only threatens to slow the transition where it’s needed most, but also raises issues of equity and energy access. Expanding clean energy in Africa, South Asia, Latin America, and other developing regions is both an economic opportunity and a necessity for meeting global climate goals. Multilateral development banks, policymakers, and private investors are now under pressure to devise mechanisms (from green bonds to climate finance facilities) that can bridge this funding gap and channel capital into the energy markets poised for the fastest growth.

Beyond finance, there are practical hurdles to sustaining the rapid pace of the transition. Infrastructure bottlenecks have emerged as a critical concern as renewable deployment ramps up. In many countries, aging electrical grids and insufficient transmission capacity are struggling to integrate the flood of new variable renewable generation. Upgrades to grid infrastructure, energy storage, and smart grid management are urgently needed to ensure reliability and to connect often-remote wind and solar farms with centers of demand. Supply chains for key materials and components also need to scale: the production of critical minerals (like lithium, cobalt, and rare earths for batteries and turbines) and manufacturing of equipment must keep up with demand. Recent years have seen supply crunches and price volatility for some clean tech inputs, partly due to geopolitical tensions and trade restrictions. These issues could temporarily slow the decline in clean energy costs or even cause project delays. Additionally, permitting and regulatory processes in some jurisdictions have not evolved quickly enough to handle the volume of renewable projects, leading to backlogs in approvals for new wind farms, transmission lines, or solar installations. All these challenges underscore that while the clean energy transition is well underway, it is not yet self-fulfilling. Strategic actions are needed to reinforce the momentum: policymakers must address grid and supply-chain constraints, update market regulations, and provide stable policy environments that encourage investment where it’s most needed. The World Economic Forum’s 2025 Energy Transition report emphasizes targeting investment to critical areas and addressing infrastructure bottlenecks as key to maintaining the current momentum. In short, the world has reached a tipping point, but whether we tip forward into a full transformation or stagnate will depend on how these systemic challenges are managed in the immediate future.

Broadening the Transition to Transportation and Industry

While clean electricity is at the heart of the energy transition, reaching climate and sustainability goals will also require transforming how we power vehicles, industries, and buildings. Here too, 2025 has brought signs of major shifts, especially in road transport, though progress in other sectors is just beginning. The past year marked a turning point in vehicle electrification: over one-quarter of all new cars sold globally in 2025 were electric (including battery-electric and plug-in hybrid models). According to the International Energy Agency, electric car sales are expected to exceed 20 million in 2025, accounting for more than 25% of worldwide auto sales, a stunning leap from just a few years ago. In fact, the incremental increase in EV sales from 2023 to 2024 (an additional 3.5 million electric cars) was greater than the total number of EVs sold in 2020. Key markets like China and Europe are leading the charge: China’s EV sales made up nearly 50% of its auto market in 2024, and are on track for around 60% in 2025. In Europe, electric cars also comprise roughly 20–25% of new sales, even amidst shifting subsidy policies. The United States is seeing EV sales accelerate as well: about 1 in 10 cars sold in 2024 were electric, a share projected to inch upward in 2025. Perhaps even more striking is the emergence of electric mobility in developing markets: in Southeast Asia, EV sales jumped nearly 50% in 2024 (reaching 9% of all car sales in that region) and are growing even faster in 2025, thanks to affordable models from China and supportive policies. Globally, this rapid electrification of transport is already displacing oil demand and emissions. By 2030, the IEA projects that EVs across all modes (cars, two-wheelers, buses, trucks) could eliminate the need for over 5 million barrels of oil per day, about 5% of total current oil consumption. The world’s vehicle fleet is not yet fully electric, but the sales trends indicate that the infamous S-curve of adoption has begun; the road transport sector may well be entering its own tipping point where electric options become the default choice for consumers and manufacturers. As one industry observer put it, the world is at a major turning point in decarbonizing road transport, with the surge in EV adoption now eating into fossil fuel demand for the first time in a meaningful way.

Decarbonizing heavy industry and long-distance transport, however, remains a formidable frontier. Sectors such as steel, cement, chemicals, aviation, shipping, and long-haul trucking are often dubbed “hard-to-abate” because they rely on processes or fuels that are difficult to replace with clean alternatives. Together, these heavy industries and transport modes account for nearly 40% of global greenhouse gas emissions. Encouragingly, solutions to cut emissions in these areas are emerging, from green hydrogen for steelmaking to sustainable aviation fuels, electrified high-temperature heat, carbon capture for cement, and advanced biofuels or battery-electric trucking. In fact, experts estimate that roughly half of the emissions from heavy industry and transport could be abated with technologies that already exist today. Several major companies have piloted innovations like hydrogen-based steel production (which can slash CO₂ per ton of steel by 90%) or carbon-neutral shipping fuels, proving the technical feasibility of cleaner industry. The challenge lies in scaling these solutions from pilot to mainstream and overcoming cost gaps. Progress to date has been limited by the need for new infrastructure (for example hydrogen pipelines and charging networks for electric trucks), the higher current cost of green fuels and technologies, and the lack of strong policy drivers in many jurisdictions. The 2025 edition of the World Economic Forum’s Industrial Transition report finds that while low-carbon technologies for heavy sectors are becoming available, “progress is increasingly constrained by the systems needed to scale them,” and calls for deeper innovation, stronger policy signals, and enabling infrastructure to accelerate the industrial transition. In practical terms, this means creating demand for green industrial products (through standards or procurement rules for green steel and green cement), building shared infrastructure like hydrogen hubs and CO₂ transport networks, and reducing the cost of capital for first-of-a-kind projects in these sectors.

Some early signs of momentum in heavy industries are visible. For example, green hydrogen production is ramping up, and several countries have announced industrial decarbonization strategies (the EU’s Net-Zero Industry Act, the U.S. hydrogen hubs program, Japan’s Green Transformation plan, to name a few). Major manufacturers and airlines have committed to using low-carbon materials and fuels, and industrial clusters are forming to aggregate clean energy demand, allowing multiple factories or firms to share renewable resources and infrastructure. These collaborative approaches can help overcome cost and risk barriers, as seen in new “green steel” hubs and sustainable aviation fuel consortia. Still, the transformation of heavy industry is at a much earlier stage than the power or automotive sectors. The coming years will be critical for moving from isolated projects to scaled deployment. The encouraging news is that the success of renewables and EVs provides a blueprint: with the right mix of innovation, policy support, and investment, even the toughest sectors can reach their own tipping points. The broader energy transition will not be truly complete until clean solutions are the default across all sectors of the economy.

An Unstoppable Transition – with Urgency to Match Its Momentum

Taken together, the events of 2024–2025 demonstrate that the clean energy transition has decisively shifted from aspiration to action. What was once considered a distant goal, a world where renewables dominate new power generation, where oil demand peaks, and where clean technologies outcompete fossil fuels, is now beginning to materialize. This moment is profoundly important. It suggests that global markets and policies have crossed a threshold whereby investing in clean energy is not only socially or environmentally driven, but economically rational and inevitable. As Fatih Birol, the Executive Director of the IEA, observed, “The transition to clean energy is happening worldwide and it’s unstoppable. It’s not a question of ‘if’, it’s just a matter of ‘how soon’.” The momentum of recent years, record renewable growth, landmark emissions plateaus, surging EV adoption, indicates that we may look back on the mid-2020s as the inflection point when the balance tipped for good.

However, reaching a tipping point is not the same as crossing the finish line. Unstoppable does not mean we can be complacent. In fact, this juncture imposes a new responsibility on governments, businesses, and society: to capitalize on the opportunity and accelerate the transition while the wind is at our backs. The coming decade to 2035 will determine whether the world solidifies the gains of this clean energy revolution or squanders them. To keep the 1.5°C climate goal within sight and ensure energy security for a growing global population, the current rates of progress must not only continue but increase in many areas. The encouraging trends, cheaper technology, strong public support, private-sector engagement, give reason for optimism. Yet, as all major analyses warn, we are still not moving fast enough. Every fraction of a degree of avoided warming, every unit of clean energy replacing fossil fuels, will count in the outcomes for global climate stability, economic resilience, and public health.

At this tipping point, the world’s largest economies and emitters carry a special responsibility. Their choices will either lock in a downward emissions trajectory or delay the peak emissions moment crucially. International cooperation is also entering a new phase: it’s less about negotiating if the world will transition, and more about coordinating how to mobilize investment, spread technology, and ensure no country is left behind in the new energy economy. Encouragingly, collaboration is growing, whether through climate finance pledges, technology partnerships, or joint initiatives to boost renewable deployment in the Global South. The energy transition is now framed not only as a climate imperative, but as a driver of economic modernization, job creation, and national security. Countries are increasingly treating clean energy as a strategic priority for competitiveness, and this adds to the sense that the transition, having tipped, will only pick up steam from here.

In summary, the clean energy transition’s tipping point is here: wind and solar power are surging ahead, electric mobility is becoming mainstream, and the grip of fossil fuels on the global economy is finally beginning to loosen. The significance of this moment cannot be overstated; it represents the dawn of a new energy era. But how bright that future shines will depend on what we do after the tipping point. With sustained commitment, smart investment, and inclusive policymaking, the momentum can become self-reinforcing, driving emissions down sharply and expanding prosperity through a low-carbon economy. In the words of one energy leader, breaking records for renewable energy is admirable, but records alone will not keep 1.5°C alive. The world has proven that a clean energy future is within reach; now it must strive with excellence and urgency to fully attain it. The tipping point has tipped, and the collective task ahead is to ensure that this historic transition not only continues, but delivers on its immense promise for current and future generations.
