China’s National Energy Administration reported that the country added 160 gigawatts (GW) of new solar power capacity in just the first three quarters of 2024 C.E. — a single-year pace that would have seemed unimaginable a decade ago. By August, China’s cumulative solar capacity had crossed 770 GW, a 48% increase year over year, with those nine months alone accounting for a massive share of everything the country had ever built.
At a glance
- Solar capacity added: China installed 160 GW of new solar power in the first nine months of 2024 C.E., according to the National Energy Administration — more than the entire installed solar base of any other country on Earth.
- Wind power growth: China’s wind energy fleet also expanded significantly, reaching 480 GW of cumulative capacity, a 20% increase year over year.
- Monthly momentum: In September 2024 C.E. alone, China added 20.9 GW of new solar capacity — a 27% jump from the previous month, suggesting the pace was still accelerating.
Why the numbers are hard to believe
To understand the scale, consider that 160 GW of new solar in nine months is roughly equivalent to the entire installed electricity generating capacity of Germany — added in less than a year. The United States, by comparison, took decades to build its current solar base of around 200 GW.
China’s 770 GW of cumulative solar capacity places it far ahead of any other nation. The country now generates more solar electricity than the next several largest solar markets combined. And that lead is widening fast.
Part of what makes this possible is cost. China dominates global solar panel manufacturing, producing the vast majority of the world’s photovoltaic modules. That dominance has driven panel prices down by more than 90% over the past 15 years, making solar the cheapest source of new electricity generation in history.
What’s driving the buildout
China has set hard national targets. The government committed to reaching peak carbon emissions before 2030 C.E. and carbon neutrality by 2060 C.E., and renewable energy is the primary mechanism to get there. Mandatory provincial quotas for renewable energy push local governments to approve and connect new projects quickly.
Massive state-owned utilities, falling equipment costs, and streamlined permitting have turned China’s electricity grid into the world’s most active construction site. Grid operators have had to rapidly expand transmission infrastructure to keep pace, connecting remote desert solar farms in the northwest to population centers in the east.
Private investment has also surged. Rooftop solar installations on homes and businesses across Chinese cities have added gigawatt after gigawatt alongside utility-scale projects. The technology has become cheap enough that households in many provinces can now generate electricity more cheaply than buying it from the grid.
The full picture
China’s renewable energy expansion carries global significance well beyond its own borders. Because China manufactures most of the world’s solar panels and a large share of its wind turbines, its industrial scale keeps driving down prices for everyone. Countries in the Global South — which historically had the least access to affordable clean energy — are now the biggest beneficiaries of that cost collapse.
At the same time, China remains the world’s largest emitter of greenhouse gases, and coal still plays a major role in its electricity system. New coal capacity continues to be approved and built, even as renewables grow at extraordinary speed. The clean energy buildout is outpacing coal’s share of the electricity mix, but the transition is not yet complete — and the pace of coal retirement matters as much as the pace of solar addition.
How quickly China’s grid shifts from coal-heavy to renewables-dominant will be one of the most consequential questions in global climate progress over the next decade. The 2024 C.E. numbers suggest the renewable side of that equation is moving faster than almost anyone predicted. International energy analysts have repeatedly revised their forecasts upward as China keeps exceeding them.

U.S. researchers cut Alzheimer’s risk by half in first-ever prevention trial
Alzheimer’s prevention may have reached a turning point after a landmark trial showed that removing amyloid plaques before symptoms appear can cut the risk of developing the disease by roughly 50%. Researchers at Washington University School of Medicine studied people with rare genetic mutations that make Alzheimer’s nearly inevitable, finding that early, aggressive treatment can genuinely alter the disease’s course. The results, published in The Lancet Neurology, mark the first time any intervention has shown potential to prevent Alzheimer’s from appearing at all, not merely slow its progression. That distinction matters enormously, since amyloid begins accumulating in the brain two…

Marie-Louise Eta becomes first female head coach in men’s top-five European leagues
Female head coach Marie-Louise Eta made history on April 11, 2026, when Union Berlin appointed her as interim head coach — becoming the first woman ever to hold a head coaching position in any of men’s top-five European leagues. The Bundesliga club made the move after dismissing Steffen Baumgart, with five matches remaining and real relegation stakes on the line. Eta, 34, had served as assistant coach since 2023 and was already a familiar, trusted presence within the squad. This was no ceremonial gesture — she was handed a survival fight, which is precisely what makes the milestone significant.

Renewables hit 49% of global power capacity for the first time
Renewable energy capacity crossed a landmark threshold in 2025, with global installed power surpassing 5,100 gigawatts and representing 49% of all capacity worldwide for the first time in history. The International Renewable Energy Agency reported a single-year addition of 692 gigawatts, led overwhelmingly by solar power, which alone accounted for 75% of new renewable installations. Clean energy now represents 85.6% of all new power capacity added globally, signaling that the transition has moved from aspiration to economic reality. The milestone carries implications beyond climate — nations with strong renewable bases demonstrated measurably greater energy security amid ongoing geopolitical instability.
