The renewable energy sector has experienced nothing short of a revolution in recent years, with 2025 marking several historic milestones that are setting the stage for even more dramatic changes in 2026. Global renewable capacity reached 49% in 2025, driven by record solar growth, representing a fundamental shift in how the world generates electricity.
Solar Power: The Undisputed Champion of Clean Energy
Solar energy has emerged as the undisputed leader in the global transition to clean energy. In 2025 alone, about 510 GW of solar capacity was added worldwide, making up nearly three-quarters of all new renewable installations, pushing total global solar capacity to around 2,392 GW by the end of the year. This extraordinary growth trajectory is reshaping energy markets worldwide and demonstrating the technology’s increasing cost-effectiveness and scalability.
The geographic distribution of solar growth reveals interesting patterns that highlight both opportunities and challenges in the global energy transition. Asia’s solar capacity grew sharply from 140 GW in 2016 to more than 1,530 GW in 2025, with China playing a key role by reaching approximately 1,202 GW of installed solar capacity by the end of 2025. This massive deployment in Asia underscores China’s dominant position in renewable energy manufacturing and deployment.
Looking ahead, electricity generation from renewables is expected to increase 60% – from 9,900 TWh in 2024 to 16,200 TWh in 2030, with renewables expected to surpass coal at the end of 2025 (or by mid-2026 at the latest) to become the largest source of electricity generation globally. This transition represents one of the most significant shifts in global energy infrastructure since the Industrial Revolution.
The Broader Renewable Landscape
While solar dominates headlines, other renewable technologies are also experiencing significant growth. 2025 saw total renewable power capacity reach 5,149 gigawatts (GW) after the addition of 692 GW, representing a 15.5% annual increase, with renewable energy dominating total capacity expansion at 85.6% share. This comprehensive growth across multiple technologies creates a more resilient and diversified clean energy ecosystem.
Wind energy continues to play a crucial supporting role in the renewable revolution, with innovative developments pushing the boundaries of what’s possible. A Chinese company launched the first megawatt-level airborne wind turbine—a 60x40x40 m helium-filled aerostat—providing electricity through a tether cable from 2,000 metres above the ground, demonstrating how technological innovation continues to unlock new possibilities for clean energy generation.
In Europe, the renewable energy transition has reached a symbolic milestone. Wind and solar energy provided 30% of EU electricity in 2025, surpassing fossil power (29%) for the first time, generating more power than fossil sources in 14 of 27 EU countries. This achievement represents a fundamental turning point in Europe’s energy system and provides a model for other regions to follow.
Carbon Capture and Storage: From Science Fiction to Commercial Reality
Carbon capture and storage (CCS) technology has transitioned from experimental concepts to commercially viable climate change solutions, with 2025 and 2026 marking critical years for deployment and innovation. Carbon capture and storage is at a turning point, with policy-driven growth in CCS capacity expected to lower costs by about 14% by 2030, mainly due to reductions in capital costs for capture technologies and in transport and storage costs.
Revolutionary Breakthrough: MIT’s Game-Changing Innovation
One of the most significant breakthroughs in carbon capture technology emerged from MIT in late 2025, offering a solution that could dramatically reduce the costs and energy requirements of carbon capture. MIT chemical engineers discovered a simple way to make carbon capture more efficient and affordable by adding a common chemical compound to capture solutions, potentially cutting costs significantly and enabling the technology to run on waste heat or even sunlight instead of energy-intensive heating, using tris to stabilize the pH of the solution used to capture CO2.
This innovation addresses one of the fundamental challenges in carbon capture: energy consumption. The tris addition stabilizes the pH, allowing the solution to absorb triple the amount of CO2, and when heated just slightly to about 60°C, tris quickly releases protons, causing the pH to drop and the captured CO2 to bubble out, enabling the solution to absorb more CO2 at room temperature and release it with mild heating.
Accelerating Natural Processes
Scientists are also finding ways to dramatically accelerate natural climate solutions. Researchers at Hebrew University and Israeli Open University developed a method to speed up geological processes that normally take thousands of years in nature so they happen within hours, published in Environmental Science & Technology. This breakthrough demonstrates how scientific innovation can harness and enhance nature’s own climate regulation mechanisms.
Commercial Deployment and Investment Trends
The commercial deployment of carbon capture technologies is accelerating across multiple sectors. As of early 2025, global operational CO2 capture and storage capacity stood at roughly 50 million tons per annum (Mtpa), though this represents just the beginning of what industry experts expect to be massive expansion.
Large industrial programs such as Germany’s €6 billion industrial decarbonization initiative, including CCS technologies, will start to roll out competitive support mechanisms in mid-2026, with private capital interest also on the rise as major energy companies have entered negotiations to attract infrastructure investment into CCUS assets.
Electric Vehicle Adoption: The Transportation Revolution Accelerates
