An effective renewable energy transition policy enabled China and India to meet growing electricity demand with wind and solar energy, rather than coal, while reducing emissions despite increasing power consumption.
Renewable energy transition policy reached a historic turning point in early 2025 when renewables generated more electricity than coal for the first time globally. Solar and wind power growth exceeded total electricity demand increases, signaling a fundamental shift in how the world generates power.
Global electricity demand rose 2.6% in the first half of 2025. Solar generation jumped 31% while wind increased 7.7%, according to energy think tank Ember. Solar alone covered 83% of the demand growth, with 306 terawatt-hours of new generation. That amount equals Italy’s entire annual electricity consumption.
Renewables now supply 34.3% of global electricity, up 1.6 percentage points from the previous year. Coal’s share dropped to 33.1% as its generation fell 0.6%. This marks the first time renewable sources have surpassed coal in the global electricity mix.
China and India drove much of the progress. Both countries met growing electricity demand with wind and solar rather than coal. Their coal use and emissions declined even as overall power consumption increased. This demonstrates how renewable energy transition policy can deliver results in the world’s most populous nations.
Other major regions moved in different directions. The European Union increased its use of gas and coal when hydropower, bioenergy, and wind generation fell short. The United States burned more coal because clean energy sources did not grow fast enough to meet rising demand. These setbacks highlight the need for more robust renewable energy transition policy frameworks.
The surge creates opportunities but also challenges. The International Energy Agency (IEA) projects solar photovoltaic technology will account for 80% of renewable capacity additions through 2030. Low costs and faster permitting drive this growth.
However, power systems face mounting pressure. More markets now experience curtailment, when excess renewable generation must be shut off because grids cannot handle it. Negative pricing events occur when supply exceeds demand so dramatically that generators pay to offload electricity.
The IEA reduced its renewable growth forecast for 2025 through 2030 by 5%. Policy changes, regulatory shifts, and market conditions prompted the adjustment. IEA Executive Director Fatih Birol emphasized the need for attention to supply chain security and grid integration as renewable energy transition policy expands globally.
Urgent investment in electricity grids, energy storage, and flexible generation capacity can address these bottlenecks. Modern battery systems store excess solar power for use after sunset. Grid upgrades allow electricity to flow from areas with abundant generation to regions with high demand. China’s battery manufacturer CATL plans to send 2,000 workers to Spain to build a new battery plant in partnership with carmaker Stellantis.
Emerging economies face distinct barriers to the deployment of renewable energy. They require financial and technical support from developed nations to address infrastructure gaps and overcome regulatory hurdles. The World Economic Forum’s Coal to Clean platform aims to accelerate funding for the retirement of coal plants in these countries.
Regional cooperation enhances the effectiveness of renewable energy transition policy outcomes. Energy ministers from the Association of South-East Asian Nations (ASEAN) met in Kuala Lumpur, Malaysia, to strengthen energy cooperation. Discussions centered on ASEAN’s energy roadmap and initiatives aimed at advancing the low-carbon energy transition and enhancing regional energy security.
Australia demonstrates how market forces can accelerate the retirement of coal. One of Queensland’s biggest coal-fired power stations could close six years earlier than expected. Economic pressure from cheap renewable energy sources makes aging coal plants uncompetitive, even without direct policy intervention.
International cooperation remains essential for effective renewable energy transition policy. Technology transfer agreements enable emerging economies to access proven renewable energy solutions. Climate finance channels capital to countries with limited borrowing capacity. Germany’s energy transition experience offers insights that could help South Africa protect the livelihoods of its many fossil fuel workers.
Latin America and the Caribbean possess favorable conditions for the advancement of clean energy. The region boasts abundant renewable resources, significant mineral wealth, and a relatively low dependence on fossil fuels. Yet a World Economic Forum analysis found the region’s readiness has not kept pace with its potential. Stronger renewable energy transition policy frameworks could unlock these advantages.
The electricity sector transformation demonstrates that rapid decarbonization is achievable. Solar and wind costs have decreased significantly, making them the most cost-effective new power sources in most markets. Manufacturing capacity continues to expand to meet soaring demand.

The next phase requires matching generation growth with grid flexibility. Countries that invest now in storage, transmission, and smart grid technology will capture the full economic and environmental benefits. Those who delay risk bottlenecks that slow the transition and raise costs.
The data shows renewable energy transition policy is delivering measurable results. With sustained commitment and strategic infrastructure investment, the shift away from fossil fuels can accelerate further in the coming years.
