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.

Wind turbines in a field, for article on clean energy investment

Global investment in clean energy matches that in fossil fuels for the first time ever in 2022

Clean energy investment hit $1.1 trillion globally in 2022, matching every dollar spent on fossil fuels for the first time ever. Electric vehicles led the charge, with spending jumping 54 percent in a single year to $466 billion. Wind, solar, batteries, and heat pumps all set records too — this wasn’t a fluke driven by one hot sector, but money moving across the whole clean economy. China poured in nearly half the total, sparking a kind of race that tends to push costs down for everyone. Parity isn’t the finish line — the world still needs to roughly quadruple this pace to hit net zero by 2050 — but it’s the moment the global energy story quietly flipped.

Electric buses, for article on Kenya electric buses

Kenya is producing its first electric buses

Electric buses are now being assembled in Kenya for the first time, marking a genuine shift in how East Africa thinks about clean public transit. A Nairobi startup called BasiGo partnered with a veteran Mombasa assembler to build 1,000 electric buses over three years — creating over 600 jobs in manufacturing, maintenance, and charging. What makes this especially promising is BasiGo’s pay-per-kilometer financing model, which makes electric buses as affordable upfront as diesel for everyday operators. Kenya’s already-clean electricity grid means these buses will run on genuinely green power. It’s a hopeful template other African cities could follow.

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.
