EVs are getting cheaper and more common all over the world. But the technology still faces major challenges in some markets, including many countries in Africa. Some regions across the continent still have limited grid and charging infrastructure, and those that do have widespread electricity access sometimes face reliability issues—a problem for EV owners, who…
Electric vehicles could be economically competitive in Africa sooner than expected. Just 1% of new cars sold across the continent in 2025 were electric, but a new analysis finds that with solar off-grid charging, EVs could be cheaper to own than gas vehicles by 2040. There are major barriers to higher EV uptake in many…
Nuclear power continues to be one of the hottest topics in energy today, and in our recent online Roundtables discussion about next-generation nuclear power, hyperscale AI data centers, and the grid, we got dozens of great audience questions. These ran the gamut, and while we answered quite a few (and I’m keeping some in mind…
In a pine forest on Michigan’s Upper Peninsula, the only active nickel mine in the US is nearing the end of its life. At a time when carmakers want the metal for electric-vehicle batteries, nickel concentration at Eagle Mine is falling and could soon drop too low to warrant digging. But earlier this year, the…
The eastern half of the US saw a monster snowstorm over the weekend. The good news is the grid has largely been able to keep up with the freezing temperatures and increased demand. But there were some signs of strain, particularly for fossil-fuel plants. One analysis found that PJM, the nation’s largest grid operator, saw…
In 2026, I’m going to be closely watching the price of lithium. If you’re not in the habit of obsessively tracking commodity markets, I certainly don’t blame you. (Though the news lately definitely makes the case that minerals can have major implications for global politics and the economy.) But lithium is worthy of a close…
Happy New Year! I know it’s a bit late to say, but it never quite feels like the year has started until the new edition of our 10 Breakthrough Technologies list comes out. For 25 years, MIT Technology Review has put together this package, which highlights the technologies that we think are going to matter…
Emissions from air freight have increased by 25% since 2019, according to a 2024 analysis by environmental advocacy organization Stand.Earth. The researchers found that the expansion of cargo-only fleets to transport goods during the pandemic — as air travel halted, slower freight modes faced disruption, but demand for rapid delivery soared — has led to…
For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium’s limited supply and volatile price have led the industry to seek more resilient alternatives. A sodium-ion battery works much like a lithium-ion one: It stores and releases energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element…
