Clean Energy's Share of Global Electricity Surpasses 40% for the First Time in Decades
What Does the 40% Milestone Mean for Clean Energy?
For the first time since the 1940s, clean energy sources, including renewables and nuclear power, accounted for over 40% of global electricity generation in 2024. This milestone, reported by energy think tank Ember, highlights the accelerating shift toward low-carbon energy solutions. Solar power emerged as a key driver of this growth, with its contribution doubling in just three years to account for 7% of global electricity generation.
This achievement underscores the growing importance of clean energy in addressing climate change and meeting rising electricity demand. With technologies like solar and wind now outpacing fossil fuels in growth, the energy transition is entering a pivotal phase.
How Did Solar Power Lead the Surge?
Solar energy has become the fastest-growing electricity source globally for an unprecedented 20 consecutive years. In 2024 alone, it added a record-breaking 474 TWh to global supply, representing an annual growth rate of 29%. This rapid expansion has been driven by falling costs, technological advancements, and supportive policies worldwide.
China played a dominant role in this surge, contributing more than half of the global increase in solar generation. India also saw its solar capacity additions double compared to 2023. These developments highlight Asia's leadership in scaling up renewable energy solutions.
Phil MacDonald, Managing Director at Ember, described solar as "the engine of the global energy transition." Paired with battery storage systems, solar is poised to meet increasing electricity demand from emerging technologies like electric vehicles (EVs) and artificial intelligence (AI).
Why Is Hydropower Still Dominant?
Despite solar's rapid growth, hydropower remains the largest single source of renewable electricity, contributing 14% of global generation in 2024. Its reliability and ability to provide consistent baseload power make it a cornerstone of many national energy strategies.
However, hydropower's growth has plateaued compared to solar and wind. As a mature technology with limited new development opportunities in many regions, it is increasingly complemented by other renewables to meet rising demand.
What Role Does Europe Play in the Clean Energy Transition?
Europe continues to lead the global clean energy movement. In 2024, clean energy accounted for an impressive 71% of Europe's electricity mix. Solar power doubled across the European Union over three years, surpassing coal as a primary energy source.
Germany emerged as Europe's top solar producer with 71 TWh generated last year. Meanwhile, Hungary achieved the highest share of solar within its national electricity mix at 25%, showcasing how diverse strategies can drive renewables adoption.
How Is Clean Energy Growth Outpacing Demand?
The Ember report indicates that clean energy growth is now exceeding the rise in global electricity demand. Between 2023 and 2024, renewables added a record 858 TWh to global supply—a 49% increase over previous records. This trend suggests that fossil fuel reliance could begin to decline permanently as clean technologies scale up.
However, challenges remain. Heatwaves and increased use of air conditioning drove fossil fuel emissions to an all-time high in 2024. The adoption of EVs, heat pumps, and AI-driven data centers is also expected to push electricity demand higher in coming years.
What Challenges Lie Ahead for Fossil Fuels?
While clean power is growing rapidly, fossil fuels still account for a significant share of global electricity generation. In some regions, political and economic factors continue to support coal and gas plants. For example, recent U.S. policies aimed at revitalising coal plants could delay progress toward reducing emissions.
Nevertheless, experts believe that renewables' economic advantages will ultimately prevail. Bruce Douglas, CEO of the Global Renewables Alliance, emphasised that "cleantech is now the driving force of economic development," signaling a shift away from fossil fuels even amid rising demand.
What Does This Mean for Homeowners and Businesses?
The global shift toward clean energy presents significant opportunities for individuals and businesses alike. Solar PV systems paired with battery storage are becoming increasingly accessible and cost-effective solutions for reducing carbon footprints while cutting energy bills.
