Egypt to build world’s first climate-positive, net-zero city
The new city, Nexgen, to be located east of Cairo, will produce more food and energy than it consumes.
Today (2017 C.E. - 2025 C.E.)
This archive spans the years 2017 through 2025, a period marked by rapid advances in clean energy, medicine, technology, and social equity. It collects documented breakthroughs, policy wins, and scientific achievements from the present era. If you want evidence that progress is real and ongoing, this is where to look.
Washington state takes strongest clean commercial building action in the U.S.
Under the new code that will take effect in July 2023, new commercial buildings will be built with high-efficiency electric heat pumps for water and space heating.
England to ban glue traps in ‘momentous victory’ for wildlife
Protected and endangered species including hedgehogs, birds, bats, and pet cats have been known to sustain injuries in glue traps, many of which are fatal.
‘Radical’ solar technology breakthrough allows energy to be stored for up to 18 years
Solar energy that lasts 18 years in a bottle? Researchers at Sweden’s Chalmers University have built a molecule that absorbs sunlight, holds it as a liquid, and releases it as electricity only when a catalyst says go. To prove it works, they charged the liquid with Swedish sun, shipped it to a partner lab in China, and three months later powered a tiny chip — just 800 nanometers thin — that turned the stored sunlight into electricity. Output is still small, but the concept is validated. If it scales, it points toward a future where clean energy isn’t tethered to grids or mining-heavy batteries, but travels quietly in a jar to wherever people need it.
Zurich begins to turn off natural gas networks
The current shutdown in Switzerland’s biggest city is due to be completed in 2024 with more areas of Zurich set to see the end of natural gas between now and 2040.
Colorado passes bill offering 10 hours per week of free universal preschool
By the fall of 2023, all 4-year-old children in Colorado will be able to attend preschool at no cost to their families.
Landmark DNA study finds 58 new mutations that cause cancer
The landmark findings from a massive study of more than 12,000 cancer patients offer researchers a trove of new resources to guide future studies on tailored cancer treatments.
Denmark announces aggressive carbon tax
Companies that do not pay for their pollution in the EU quota system now must pay DKK 750 per ton of CO2 they emit.
Formerly warring factions in Burundi have now planted over 150 million trees together since 2018
In 2018, Burundi launched a vast national reforestation program to boost the country’s dwindling forest cover, which will run until 2025.
First COVID-19 breath test authorized for use in U.S.
A COVID-19 breath test just cleared a major hurdle: the FDA has authorized the first device that can detect the virus from a single exhale, returning results in about three minutes. Made by InspectIR, the device picks up a signature pattern of five compounds the body releases during infection, and in a study of nearly 2,500 people it correctly flagged 91 percent of positive cases. No swabs, no lab. Beyond this moment, the authorization is a real proof of concept for breath-based diagnostics — a field researchers have long hoped could one day help detect cancers, kidney disease, and other conditions, especially in communities where traditional testing is hardest to reach.
