The Global Renewable Energy Landscape in 2026
Renewable energy is now central to the global power transition. In 2026, governments, businesses and investors are accelerating the move towards low-carbon electricity to improve energy security, reduce exposure to fossil-fuel price volatility and support net-zero commitments.
The latest complete global data shows that renewable power capacity reached 5,149 GW by the end of 2025, following a record 692 GW of new capacity in a single year. That represented annual growth of 15.5%, with renewables accounting for 85.6% of all new electricity-generating capacity added globally.
Solar and wind remain the main drivers of this expansion, but the transition is increasingly about more than generation alone. Electricity networks, battery storage, flexible demand and smarter energy management are becoming essential to integrating renewables reliably and making the most of lower-cost clean electricity.
- Solar PV remains the fastest-growing renewable technology. Global solar capacity reached approximately 2,392 GW at the end of 2025 after a record 511 GW was added during the year. Solar represented roughly three-quarters of all new renewable capacity, reflecting its scalability across utility-scale projects, commercial rooftops and on-site generation.
- Wind energy continues to play a major role in diversified power systems. Around 159 GW of wind capacity was added globally in 2025, taking total installed wind capacity to approximately 1,291 GW. Wind remains particularly important for balancing solar generation across different seasons and times of day, as well as supporting large-scale decarbonisation in mature energy markets.
- Hydropower remains a foundation of renewable electricity supply. Global renewable hydropower capacity reached around 1,296 GW by the end of 2025. Beyond energy generation, hydro can provide flexibility and system-balancing value in many grids, a capability that becomes increasingly important as variable solar and wind capacity grows.
- Battery storage and grid infrastructure are becoming critical enablers. Higher shares of solar and wind require electricity systems that can store energy, respond flexibly to demand and move power efficiently across networks. For commercial organisations, combining solar PV with battery storage can help increase on-site consumption, manage peak demand and improve operational resilience.
Investment is continuing to follow the transition. Global spending on clean-energy technologies, including renewables, grids, storage, efficiency, electrification, nuclear and low-emissions fuels, was expected to reach around $2.2 trillion in 2025, roughly twice the investment directed towards fossil fuels. Solar investment alone was expected to reach approximately $450 billion in 2025, making it the largest single category of global energy investment.
For businesses, the opportunity is increasingly practical rather than theoretical. Commercial solar and battery storage can help organisations lower energy costs, reduce carbon emissions and strengthen resilience against grid constraints and volatile electricity prices. The strongest projects are designed around each site’s demand profile, operating hours, tariff exposure, available space and business-continuity requirements.
Breakthrough Technologies Driving the Future of Renewable Energy
The future of renewable energy lies in breakthrough technologies that enhance efficiency, lower costs, and offer new ways to generate and store energy. Here are some key innovations driving the sector:
- Advanced Solar Technologies: Next-generation solar panels, such as perovskite solar cells, promise to deliver higher efficiency at a lower cost than traditional silicon-based panels. 3D solar cells and flexible solar panels are also emerging, offering new residential, commercial, and industrial applications.
- Energy Storage Innovations: Battery storage is essential for stabilising renewable energy grids. Solid-state batteries are set to revolutionise energy storage, offering greater energy density and safety. Hydrogen storage is another game-changer, as hydrogen can store excess renewable energy for longer durations.
- Artificial Intelligence in Energy Management: AI is increasingly important for optimising renewable energy systems. Machine learning algorithms can predict energy demand, optimise grid operations, and improve the efficiency of solar and wind farms.
- Offshore Wind and Tidal Power: As offshore wind farms grow in size, advances in floating wind turbines and turbine blade technology are increasing the efficiency and scalability of these projects. Similarly, tidal energy is gaining momentum with new, more efficient tidal turbines.
