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.

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

Nine U.S. states have inked an agreement to promote climate-friendly heat pump sales. The memorandum of understanding sets a 2030 target for heat pumps to make up 65% of residential heating, cooling, and water heating equipment sales. By 2040, the goal is for heat pumps to account for 90% of the HVAC and water heating market. The states on board with the agreement include: California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island.

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.

25% of new car sales in China were fully electric in 2023 for the first time ever

China’s EV transition crossed a remarkable threshold in 2023, with one in four new cars sold being fully battery-electric — and plug-in vehicles of all types capturing 37% of the market. That’s a stunning leap from just three years earlier, when plug-ins held only 6.3% of sales. Affordable pricing from Chinese automakers like BYD, plus the rise of range-extended models that ease driver anxiety, are fueling the shift. Analysts note that once EV adoption passes roughly a quarter of a market, momentum tends to build on itself as charging networks grow and electric becomes the default choice. It’s a hopeful signal that the world’s biggest car market may be tipping toward clean transportation faster than anyone expected.

Rio Tinto signs contract for Australian grid’s first gigawatt scale solar project

Rio Tinto has signed on to buy all the power from a 1.1 gigawatt solar farm in Queensland — the largest solar project ever contracted on Australia’s main grid. The electricity will flow to Rio Tinto’s alumina refinery, aluminum smelter, and boron plant near Gladstone, some of the most power-hungry industrial sites in the country. Built by Danish developer European Energy, the Upper Calliope farm will deliver clean energy at the scale of a large coal plant when the sun is shining. Heavy industry has long been one of the trickiest pieces of the climate puzzle, so a commitment this big from a global mining giant is a real signal that even the most energy-intensive sectors can start to run on sunshine.

Artist's concept of a solar power satellite in place, for article on space solar power

First ever space-to-Earth solar power mission succeeds

Space-based solar power just cleared a milestone scientists have been chasing since the 1970s: a Caltech satellite spent a year in orbit, collected sunlight, and beamed it wirelessly back to a ground receiver on Earth. The SSPD-1 mission completed all three of its planned experiments, including testing an origami-inspired panel that unfolds without hinges and a purpose-built microwave transmitter. The appeal is simple — above the atmosphere, the Sun never sets, no clouds get in the way, and power could flow around the clock. Caltech’s team is honest that commercial-scale space solar is still years off, with cost and radiation durability to solve. But moving this idea from whiteboard to working demonstration brings humanity a real step closer to truly continuous clean energy.

Microsoft places massive 12GW solar module order, bolstering U.S. solar supply chain

Microsoft just inked a deal for 12 gigawatts of American-made solar panels — enough to power more than 1.8 million homes a year. The eight-year agreement with manufacturer Qcells will be supplied by a Georgia factory that handles everything from raw silicon to finished module under one roof, a rarity in an industry where most panels travel across oceans before reaching a project site. By committing to such a long runway, Microsoft gives manufacturers the confidence to build out capacity that might otherwise sit on the drawing board for years. It’s a glimpse of what the clean energy transition looks like when corporate demand, smart industrial policy, and domestic factories actually pull in the same direction.

Offshore wind sites are delivering power to the grid for the first time in U.S. history

In December 2023, Danish wind energy developer Ørsted and the utility Eversource announced that their first turbine was sending electricity from what will be a 12-turbine wind farm, South Fork Wind, 35 miles east of Montauk Point, New York. Now, the joint owners of the Vineyard Wind project have announced the first electricity from one turbine at what will be a 62-turbine wind farm 15 miles off the coast of Massachusetts.

U.K. use of gas and coal for electricity at lowest since 1957

The UK’s electricity grid just hit a milestone unseen since 1957: gas and coal together produced less power than in any year of the last seven decades. Renewables — wind, solar, hydro, and biomass — supplied a record 42% of electricity in 2023, while coal alone has fallen 97% since 2008 and is set to disappear from the grid entirely when Britain’s last coal plant shuts in September 2024. Add nuclear, and more than half of the country’s electricity now comes from sources that emit no carbon. The deeper significance is simple: a major industrialized economy can run mostly on clean power not as a forecast, but as a lived, ordinary year — proof other countries can point to.

In Scotland, renewable power has outstripped demand

For the first time, in 2022, Scottish renewables generated more power than the country used, new government figures show. The growth of wind power, coupled with a small drop in electricity consumption, meant that the volume of electricity produced by renewables in Scotland was equal to 113 percent of demand.
