Clean & renewable energy

This archive tracks real progress in clean and renewable energy — from solar and wind expansion to grid upgrades and policy wins. Each story focuses on what’s working, where, and why it matters for people and the planet.

Charging an EV

Biden administration rolls out new tailpipe rules that will boost EVs and hybrids

New U.S. tailpipe pollution rules are projected to prevent more than 7 billion metric tons of planet-warming emissions over their lifetime, cutting passenger car pollution nearly in half by 2032 compared to 2026 levels. Rather than mandating a hard electric vehicle quota, the EPA lets automakers mix battery EVs, plug-in hybrids, and more efficient gas engines to hit the same pollution ceiling. A former EPA transportation chief called it the single most important climate regulation in American history, and cleaner air will especially benefit communities living near busy roadways. With transportation being the largest source of U.S. climate pollution, this rule nudges the world’s second-biggest car market closer to the pace of change already underway in Europe and China.

The world’s largest clean energy plant is now under construction in the Indian state of Gujarat

The world’s largest renewable energy facility is rising from a salt desert in western India, sprawling across more than 200 square miles — roughly five times the footprint of Paris. Once complete in about five years, the Khavda Renewable Energy Park is expected to power 16 million Indian homes with clean electricity. Developer Adani Green Energy chose the barren Gujarat site precisely because it offers vast scale without displacing communities or wildlife, removing a common obstacle to major infrastructure. The project anchors India’s push toward 500 gigawatts of non-fossil capacity by 2030. For a country facing the world’s steepest energy demand growth in the decades ahead, Khavda is a hopeful sign that developing nations can leapfrog the fossil-heavy path wealthier countries once took.

America’s first utility-scale offshore wind farm is now delivering energy to the grid

Offshore wind power is officially flowing in the United States. New York’s South Fork Wind just switched on all 12 turbines about 35 miles off Montauk, sending roughly 130 megawatts to Long Island and the Rockaways — enough for around 70,000 homes and businesses. Hundreds of union workers across three Northeast ports built the farm, including the country’s first domestically built offshore wind substation, laying the groundwork for a supply chain that barely existed a decade ago. It’s a modest start by European standards, but it proves America can actually permit, finance, and complete a utility-scale offshore project — the kind of foundation every larger clean energy ambition has to be built on.

DSV rooftop solar in Horsens

World’s largest rooftop solar power plant to be built in Denmark

Rooftop solar is about to hit a new high in Horsens, Denmark, where a 35-megawatt system will blanket a logistics center spanning more than 300,000 square meters — roughly the area of 42 soccer pitches. Danish firm SolarFuture, known for its tricky install on the curved roof of the Copenhagen Opera, is leading the build, with completion targeted for December 2024. The project shows what becomes possible when warehouses are designed from day one to carry panels, turning ordinary industrial roofs into serious power plants. As corporations around the world look for on-site clean energy, a single rooftop in a town of 60,000 quietly raises the bar for everyone else.

96% of all new power capacity in the U.S. in 2024 will be carbon-free

Clean energy just crossed a quiet threshold in the United States: 96 percent of new electricity capacity planned for 2024 is zero-carbon, while new natural gas additions have fallen to a 25-year low. The real game-changer is battery storage, which lets solar and wind power flow steadily even when the sun sets or the wind dies down. Utility-scale batteries alone account for 14.3 gigawatts of planned additions this year, dwarfing new gas builds. Tax credits from the 2022 Inflation Reduction Act helped unlock a wave of domestic battery manufacturing, bringing costs down and deployment up. It is a hopeful signal that the long-promised clean grid is finally being built, not just imagined.

Turkish scientists develop “bumpy” solar panel concept that can harvest up to 66% more energy

Dome-shaped solar cells could absorb up to 66% more light than their flat counterparts, according to new simulations from a research team at Abdullah Gül University in Türkiye. The trick is geometric: tiny hemispherical bumps catch sunlight from many angles at once, acting almost like little lenses that funnel light into the cell. That means solar power could finally work well on surfaces that flat panels struggle with, like clothing, curved windows, greenhouse roofs, and wearable medical devices. The design still needs to be built and tested in the real world, but it points toward a future where solar generation lives quietly inside the everyday surfaces around us, rather than only on dedicated rooftops.

Allegiant Stadium exterior with curved facade and stadium signage, host of Super Bowl 58

Super Bowl 58 first to be fully powered by renewable energy

Renewable electricity powered Super Bowl LVIII from end to end, drawing on more than 621,000 solar panels installed across the Nevada desert. Allegiant Stadium runs year-round on solar through a 25-year agreement with NV Energy, so this wasn’t a one-weekend gesture dressed up for the cameras — it’s how the building keeps the lights on every day. The same solar farm produces enough electricity to power around 60,000 homes, easily absorbing the game’s 10-megawatt demand without strain. When the most-watched event in American sports runs smoothly on sunshine, the old worry that renewables can’t be trusted with serious loads gets a lot harder to argue, anywhere in the world.

Nine U.S. states, including California and New York, sign heat pump agreement to clean up air pollution

Heat pump adoption just got a major coordinated push, as nine states spanning roughly a third of the U.S. population aligned around shared targets to electrify residential heating at scale. Fossil-fueled heating equipment across these states releases more than 138,000 tons of nitrogen oxide annually — exceeding power plant emissions — with at least 40 percent of new investments directed toward low-income households. Because the agreement isn’t legally binding, each state must build its own policies to deliver. When large states move together, manufacturers and investors take notice — a market signal that can reshape supply chains before mandates arrive.

Wind power overtakes natural gas in the E.U. for first time ever

Wind energy outproduced natural gas across the European Union for the first time ever in 2023, according to an analysis from the energy think tank Ember. Renewables together supplied nearly half of Europe’s electricity that year, while coal generation fell by 26 percent — the steepest single-year drop the continent’s power sector has ever recorded. Analyst Sarah Brown called it a “monumental shift,” noting that wind and solar are now becoming the backbone of the grid rather than an add-on. What makes this especially hopeful is that it happened during an energy crisis, when many expected Europe to retreat to coal. Instead, the continent leaned harder into clean power — and showed the rest of the world what’s possible.

Ethiopia becomes first country to ban combustion-powered vehicles

Ethiopia just became the first country anywhere to ban the import of gasoline and diesel cars, with the policy announced in late January 2025. What makes this remarkable is the foundation underneath it: every kilowatt powering an Ethiopian EV comes from renewable sources, mostly hydropower, so these vehicles are genuinely zero-emission from the moment they plug in. The shift is also deeply practical — Ethiopia has been spending around $6 billion a year on oil imports, with most of that fueling vehicles, money that can now flow into homegrown clean transport instead. Wealthier nations have led on EV adoption, but none have drawn this line. Ethiopia just showed the rest of the world a bolder version of what’s possible.
