The world’s clean energy supply reached 40% in 2024, led by China’s rapid solar expansion.
If you flip a light switch, charge your phone, or run your washing machine, nearly half the electricity powering those everyday tasks now comes from clean sources like wind and solar. That’s the reality for much of the world in 2024. Clean energy now supplies 40% of the world’s electricity, a new global record driven largely by a solar boom in China.
But while this is good news, it’s not good enough. The world is still not on track to meet the international goal of tripling clean energy capacity by 2030. According to a new report cited by the Associated Press, we’re expected to fall 28% short of that target unless countries speed up their efforts.
In 2024, China added more solar power in one year than the U.S. has in its entire history. The country’s total solar capacity is now nearly 887 billion watts. That’s enough to power about 110 million U.S. homes for a year.
China’s dominance in solar power is helping to drive down global prices, making clean energy more accessible worldwide. However, this strong growth also highlights countries that aren’t keeping pace.
Here’s how other nations compare:
- United States: While clean energy growth continues, the pace has slowed due to policy rollbacks. The U.S. installed around 40 gigawatts of solar capacity in 2024, far less than China’s 216 gigawatts.
- European Union: Together, EU countries added approximately 56 gigawatts of new solar in 2024. Germany led the bloc, with strong government support and financial incentives.
- India: India added approximately 18 gigawatts of solar capacity in 2024, but it still struggles with grid infrastructure and financing challenges.
- Brazil: Brazil continues to grow its clean energy supply through hydroelectric power, which makes up more than 60% of its electricity mix.
While global progress varies, over 92% of all new electricity capacity added in 2024 came from renewables. That indicates a significant shift, but it needs to accelerate further.
40% of the world’s electricity is a massive shift in how the world is powered. Globally, total electricity use in 2024 was roughly 29,000 terawatt-hours (TWh). That means approximately 11,600 TWh of the clean energy supply came from renewable sources, including solar, wind, hydro, and geothermal.
To put it simply, that’s enough electricity to power the entire United States for over 30 years at current usage levels. And it’s only going up.
But there’s still a long way to go. Fossil fuels (coal, oil, and natural gas) still account for around 60% of global electricity generation. Those fuels release carbon dioxide and other pollutants that contribute to climate change and exacerbate air quality issues.
In 2023, nearly 200 countries agreed to triple global renewable energy capacity by 2030. This target is critical to keeping global warming below 1.5°C, the limit scientists say we must not exceed to avoid the worst climate impacts.
So what would it actually take to meet that goal?
- Current global renewable capacity: Roughly 3,500 gigawatts.
- Target capacity by 2030: Around 10,500 gigawatts.
- Annual increase needed: About 1,000 gigawatts per year through 2030.
In 2024, the world added around 500 gigawatts. That’s a record, but only half of what’s needed annually. Without a sharp acceleration, the world’s clean energy supply won’t meet the 2030 target.
Clean energy isn’t just about the climate. It has real, everyday effects on people’s lives.
Burning fossil fuels creates fine particles that enter our lungs and bloodstream. These pollutants are linked to asthma, heart disease, and early death. According to the World Health Organization, air pollution from fossil fuels causes about 4.2 million deaths every year.
Switching to solar and wind helps clean the air. It also cuts energy bills over time. As solar and wind energy become more affordable, households can save money, especially through home installations or community solar programs.
Clean energy also creates jobs. The solar industry alone supports more than 250,000 U.S. workers. Expanding the world’s clean energy supply could provide millions more jobs in manufacturing, installation, and maintenance.
Under President Trump, the United States has reduced its international climate commitments and rolled back environmental protections. These changes may slow the growth of clean energy and discourage investment.
This policy shift matters. The United States is the second-largest polluter in the world, after China. Without strong government support, the United States risks falling further behind in both climate action and clean energy leadership.
Meanwhile, cities and states are trying to fill the gap. California, New York, and others continue to invest in wind and solar, aiming for 100% clean electricity by mid-century.
The clean energy revolution is clearly underway, but momentum isn’t enough. Global leaders need to back promises with action. That means more public funding, fewer fossil fuel subsidies, faster permitting for clean energy projects, and stronger grid infrastructure.
António Guterres, Secretary-General of the United Nations, said it best: “Renewable energy is powering down the fossil fuel age. Record-breaking growth is creating jobs, lowering energy bills, and cleaning our air.”
The challenge is clear. The tools are available. But time is running short.
