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.

Fiery glowing atomic nucleus abstract background, for article on fusion net energy gain

American fusion scientists claim net energy gain, in potentially huge renewables breakthrough

Fusion energy just cleared a barrier scientists have been chasing since the 1950s — producing more energy from a reaction than was needed to trigger it. Researchers at Lawrence Livermore National Laboratory achieved this by blasting tiny hydrogen fuel capsules with lasers until they released roughly 20 percent more energy than the lasers delivered. The result doesn’t mean fusion power plants are imminent; enormous engineering challenges remain between this laboratory milestone and a working grid. But it does confirm that fusion’s central promise is physically real — and that gives scientists, investors, and policymakers something genuinely new to build on.

Lightyear One, for article on solar electric car

World’s first solar car goes into production

Solar-powered cars have moved from moonshot idea to manufacturing reality — and that shift matters more than any single vehicle rolling off the line. Lightyear’s debut model uses curved solar arrays across its roof and hood, harvesting enough sunlight to cover up to 40 miles daily — matching most people’s actual driving habits. At $255,000, it targets early adopters, though with solar panel costs having dropped over 99% since the 1970s, wider accessibility may follow. A car that generates its own fuel from sunlight quietly answers one of the strongest critiques of electric vehicles.

Rolls-Royce & easyJet hydrogen engine, for article on hydrogen jet engine

World’s first test run of a hydrogen jet engine proves a success

Hydrogen-powered flight moved from theory to reality when Rolls-Royce and easyJet successfully ran a modern jet engine on green hydrogen produced entirely from wind and tidal energy. Unlike battery-electric approaches, hydrogen burns clean — releasing water vapor instead of carbon dioxide — and this test proved a real engine can handle it. Aviation has been one of the hardest sectors to decarbonize, so a confirmed proof of concept opens a genuine path forward. Every major breakthrough in flight history started exactly here: on the ground, with an engine, and a question that finally got answered.

China turns on the world’s largest and most efficient compressed air energy storage plant

Clean energy storage just took a major leap forward, and it happened without a single fossil fuel involved. China’s new compressed air facility in Zhangjiakou runs entirely on thermodynamic processes, storing up to 400 MWh and operating at 70.4% efficiency — well above the 40–52% typical of existing systems. That’s enough to supply more than 132 GWh to the local grid annually, while avoiding roughly 109,000 tons of CO₂ each year. Proving that utility-scale, non-lithium storage can work commercially gives the global clean energy transition a powerful new tool to build on.
