In 2023, the world reached a significant milestone—over 40% of global electricity was generated from low-carbon sources. This is a record that hasn’t been seen since the 1940s when the global grid was a fraction of its current size and hydroelectric power dominated the scene. Today, solar energy has become a driving force in the push to create an entirely clean electricity grid. According to Ember, a clean energy think tank, solar production has grown to the point where it can now power an entire country, such as India.
However, the transition to clean energy faces challenges. Last year, the electricity sector saw record-breaking emissions, with 14.6 billion tons of CO2 produced. Extreme weather events, such as heatwaves that drive up cooling demands, are partly to blame for this uptick. As the world faces its hottest year on record, the urgency to accelerate the energy transition becomes ever clearer.
Europe’s Leadership in Clean Energy
While the global average for clean energy remains at 40%, Europe is far ahead of the curve. The European Union (EU) is projected to generate 71% of its electricity from clean sources in 2024, with nuclear power included in this mix. This positions Europe as a global leader in the clean energy race. Beatrice Petrovich, a senior analyst at Ember, states that Europe is now showing the world how to effectively scale up renewable energy, with solar, wind, and hydropower accounting for almost half (47%) of the EU’s electricity production.
Countries like Germany, Spain, and Hungary have seen significant strides in solar energy production. Germany, for example, produced 71 TWh of solar energy last year, securing its place among the top six global producers. Hungary, in particular, has emerged as the world leader in solar energy share, with 25% of its electricity generated from solar sources. This success can be largely attributed to generous residential solar incentives, which have driven capacity growth. While these incentives are now finished, the installed panels will continue to contribute to Hungary’s energy mix for decades.
Solar Power Is a Team Effort
The growth of solar energy is not confined to any single country. Across the EU, solar energy production has nearly doubled in recent years, with 11% of Europe’s electricity now coming from solar power—surpassing coal for the first time. This widespread adoption across multiple nations highlights the flexibility and scalability of solar technology. Seven EU member states rank among the top 15 countries with the highest solar energy shares, proving that solar power is a pan-European success story.
Even with less-than-ideal weather conditions in 2024, the increase in the number of solar panels, including rooftop installations, has enabled the EU to generate more electricity. The growth in solar capacity has continued despite high penetration rates, showing no signs of slowing down.
The California Model: A Vision for Europe?
The success of solar and battery integration in California offers a glimpse into what could be possible in Europe in the coming years. Last year, California’s use of solar energy combined with batteries helped meet one-fifth of the state’s electricity demand during evening peak times. This was a major improvement from just three years ago when only 2% of demand was met in this way. As countries like Ireland adopt large-scale battery storage technology, they too may begin to replicate California’s success.
Beatrice Petrovich suggests that Europe must now move beyond its current trajectory and embrace more solar and wind power while also improving its energy storage and distribution capabilities. This involves creating a more intelligent grid, which will be key to managing the energy produced by renewables efficiently.
Clean Energy: A Solution to Global Challenges
As the world faces increasingly complex challenges—from the rise of artificial intelligence to geopolitical tensions—clean energy is emerging as a crucial part of the solution. The transition to renewable energy can help meet the growing demand for electricity, which is being driven by new technologies like electric vehicles and data centers.
Despite some setbacks, such as a slight increase in fossil fuel consumption due to heatwaves, the clean energy sector is expected to grow rapidly enough to keep pace with demand. According to Petrovich, every country is capable of meeting its growing electricity needs through clean energy. Europe’s response to Russia’s invasion of Ukraine, for example, has underscored the importance of energy security and increased the push for renewable energy sources.
In conclusion, as the world moves past 40% clean electricity, the momentum toward a sustainable energy future is undeniable. With continued investment in solar, wind, and energy storage technologies, the global transition to a clean energy future is not only possible—it’s already happening. The world is on the path to a cleaner, more sustainable energy future, and Europe is leading the way.
