For the first time in recorded energy history, more new electricity-generating capacity came from renewable sources than from fossil fuels and nuclear power combined. The International Energy Agency confirmed in 2016 C.E. that renewables — led by solar and wind — accounted for more than half of all new power capacity added globally the previous year. It was a quiet turning point, easy to miss in the daily noise of energy politics, but it marked a shift decades of investment and policy had been building toward.
Key findings
- Renewable energy capacity: Renewables made up roughly two-thirds of all new power capacity added worldwide in 2015 C.E., the year covered by the IEA report released in 2016 C.E.
- Solar power growth: Solar additions alone reached a record high, with more solar capacity installed than any other single energy technology that year.
- Wind energy expansion: Wind power added more capacity globally than any previous year on record, with China leading installations by a wide margin.
What drove the shift
The story behind the numbers is one of compounding progress. The cost of solar photovoltaic panels had fallen by more than 80% over the previous decade. Wind turbine costs had dropped sharply too. What once required heavy government subsidy was becoming the cheapest option in many markets on pure economics alone.
China played an outsized role. By 2016 C.E., it was the world’s largest installer of both solar and wind capacity, driven by serious air quality concerns in its major cities and a strategic national investment in clean energy manufacturing. Germany’s Energiewende policy had shown that a large industrial economy could sustain high shares of renewables on its grid. Denmark was regularly running on more than 100% wind power for short periods. These weren’t experiments anymore — they were working systems.
Emerging economies were part of the picture too. Countries across Africa and South Asia were leapfrogging fossil fuel infrastructure entirely in some regions, installing solar microgrids where grid extension would have taken decades. The milestone wasn’t solely a story of wealthy nations — it reflected decisions being made across income levels and continents.
The math of energy transition
Capacity and generation are different things. A solar panel installed counts toward capacity, but it only produces electricity when the sun shines. So while renewables led on new capacity additions, fossil fuels still generated the majority of the world’s electricity in 2016 C.E. That distinction matters when reading the milestone honestly.
Still, capacity is where the future gets built. Every megawatt of renewable capacity added displaces some future demand for fossil fuel generation. The IEA’s World Energy Outlook 2016 noted that renewable electricity was on track to become the largest source of new generation globally for years to come — a projection that has since proven accurate.
Lasting impact
The 2016 C.E. milestone set a floor that has only risen. Renewables have continued to outpace all other forms of new generation in every subsequent year. By the early 2020s C.E., solar alone was adding more capacity annually than the entire global coal fleet. The economic logic that drove the 2015 C.E. numbers has deepened: in most of the world, building new wind or solar is now cheaper than running existing coal plants.
The milestone also shifted the political and financial conversation. Once renewables demonstrably led capacity additions, the argument that the energy transition was hypothetical or distant became harder to sustain. Energy investment analysts began modeling fossil fuel infrastructure as stranded asset risk. Insurance markets, pension funds, and central banks started treating climate risk as financial risk in ways they hadn’t before.
Communities that had long borne the health costs of fossil fuel extraction and combustion — often lower-income populations and Indigenous communities located near power plants, pipelines, and refineries — stood to benefit most from a genuine transition. Whether the pace of that transition matches the urgency of those harms remains an open and contested question.
Blindspots and limits
The headline figure measured capacity added, not electricity generated — a distinction that obscures how much fossil fuel still dominated actual power production. The transition also remained deeply uneven: some nations were accelerating fast, while others, particularly those with large fossil fuel reserves and limited financing, faced structural barriers the capacity statistics didn’t capture. And the environmental footprint of renewable manufacturing — mining for lithium, cobalt, and rare earth elements — raised legitimate questions about supply chains that the good-news framing of 2016 C.E. didn’t fully reckon with.

Ghana declares its first marine protected area to rescue depleted fish stocks
Ghana’s marine protected area — the country’s first ever — marks a historic turning point for a nation gripped by a quiet fisheries crisis. Established near Cape Three Points in the Western Region, the protected zone restricts or bans fishing activity to allow severely depleted fish populations to recover. Ghana’s coastal stocks have fallen by an estimated 80 percent from historic levels, threatening food security and the livelihoods of millions of small-scale fishers. The declaration also carries regional significance, potentially inspiring neighboring Gulf of Guinea nations to establish coordinated protections of their own.

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.
