This archive tracks real progress in clean and renewable energy — from solar and wind expansions to grid breakthroughs and policy wins. More than 850 articles document what’s working, where it’s scaling, and who’s driving the shift away from fossil fuels. If you follow energy news for signal rather than noise, this is a useful place to start.
For the first time in 2040 C.E., more than half of American homes are heated by heat pumps. The milestone reflects 15 years of compounding growth in sales, cold-climate breakthroughs, and policy support — but roughly half of homes still haven’t made the switch.
China EV sales could hit 99% of new passenger cars by 2039, effectively closing the combustion era in the world’s largest auto market. The momentum is already visible: fully electric cars made up 25% of new sales in 2023, with plug-in hybrids pushing the total higher. If the trend holds, cleaner air and quieter streets become the everyday inheritance of a generation.
The UK’s biggest clean energy auction ever has awarded contracts for 8.4 gigawatts of new renewable capacity, enough to power roughly 12 million homes. The result marks a dramatic turnaround after the 2023 auction attracted zero offshore wind bids when strike price caps failed to reflect real construction costs. After adjusting those caps, developers returned in force across offshore wind, onshore wind, and solar projects. The outcome significantly advances Britain’s goal of fully decarbonizing its electricity grid by 2030, while also signaling to European markets that stalled clean energy programs can be successfully recalibrated.
China fusion plasma record: Scientists have sustained superheated fusion plasma for more than 17 minutes inside an experimental reactor, the longest confinement time ever recorded at that temperature. China’s EAST tokamak held plasma at 100 million degrees Celsius for 1,066 seconds, more than doubling its own previous record. This matters because sustained plasma confinement is one of fusion energy’s hardest engineering challenges, and solving it brings humanity closer to clean, near-limitless power. Fusion produces no carbon emissions and uses hydrogen isotopes from seawater as fuel, making this milestone genuinely significant for the global energy future.
Uruguay renewable electricity now powers 97–99% of the country’s grid — one of the highest shares on Earth — and has done so reliably for years. Driven not by climate idealism but by a practical decision to escape costly fossil fuel imports, Uruguay transformed its entire energy system in roughly a decade using only proven technologies like wind, hydro, solar, and biomass. The result has been stabilized energy prices, thousands of new jobs, and a grid resilient enough to catch the attention of the IEA and World Bank. For developing nations still dependent on imported fuels, Uruguay’s model offers a concrete, replicable blueprint.
Renewable energy tripling is now within reach, with the world on track to hit the global goal set at COP28 in 2023. For the fourth straight year, record amounts of wind and solar capacity are being added worldwide, growing at more than twice the annual rate needed to reach the target by 2030. Solar power is leading the surge, now the cheapest source of new electricity in most of the world. The milestone matters because it signals a fundamental shift in how humanity generates power — and because cleaner, cheaper domestic energy strengthens national security and household budgets alongside reducing emissions.
Benin solar energy policy marks a significant turning point for West Africa, as the country has formally committed to making solar photovoltaics its primary electricity source by 2030. For years, Benin depended heavily on power imports from neighboring nations, leaving households and businesses vulnerable to supply disruptions and price volatility. The new strategy pursues both utility-scale solar farms and off-grid rural installations, extending reliable electricity to communities that centralized infrastructure has never consistently served. The commitment aligns with UN Sustainable Development Goal 7 and positions Benin to attract international climate finance at a moment when clean energy investment is accelerating across the continent.
Solar panel imports across Africa surged 60% in the year to June 2025, reaching a record 15,032 MW in the most geographically widespread clean energy expansion the continent has ever seen. Unlike previous spikes driven by a single country’s crisis, this wave spread across 20 nations setting new import records, including dramatic rises in Algeria, Zambia, Nigeria, and countries where reliable electricity has never existed. For nearly 600 million Africans without power access, decentralized solar offers a faster, cheaper path than waiting for centralized grids to arrive. The surge suggests energy leapfrogging is happening in practice, not just theory.
Renewable energy milestone: For the first time in recorded history, clean energy sources generated more electricity globally than coal over a single half-year period, according to energy think tank Ember. Solar drove 83% of new electricity demand growth and now produces 58% of its output in lower-income countries, representing a genuine shift in who benefits from the energy transition. Even as global electricity demand rose, clean energy growth was strong enough to push a slight decline in combined coal and gas use. The forces behind this shift — collapsing costs, expanding markets, and growing manufacturing capacity — are structural, not temporary.
Global electric vehicle sales surpassed 20 million units in 2025, a 27% year-over-year increase that marks a fundamental turning point in transportation history. For the first time, consumer economics rather than government policy is driving adoption, with buyers in price-sensitive emerging markets across Southeast Asia and Latin America choosing EVs without heavy subsidies. Declining battery costs are pushing electric vehicles toward mass-market affordability across dozens of countries simultaneously. This geographic and economic diversification makes the transition significantly more resilient than one dependent on any single government’s policy commitments.
