📉 China's CO2 emissions continue to decline – the peak may already have been passed
China's carbon dioxide emissions fell by one percent during the first half of 2025 and continue the downward trend that began in March 2024. The declining trend opens the possibility that China's emissions may already have reached their peak, years before the "before 2030" target.
📉 Solar power with batteries became 22 percent cheaper in one year
The cost of solar power with batteries dropped 22 percent during 2024 and 43 percent since 2019. Solar power with batteries now costs around 100 dollars per megawatt hour in sunny cities, which is cheaper than coal and nuclear power.
🚗 Electric cars sold at record pace globally in 2025
Global sales of electric vehicles reach nearly 22 million cars in 2025, an increase of 25 percent from the previous year. Electric vehicles will account for a quarter of all passenger cars sold globally this year.
🚾 Solar energy can recover ammonia from wastewater and reduce climate emissions
Researchers have developed a cheap method for recovering ammonia from wastewater using solar energy. The system can both purify wastewater and provide farmers with cheaper fertilizer. The economic analysis shows that the system can pay for itself in 3.5 years.
🔋 AI creates new battery materials that could revolutionize energy storage
The AI models identified five new porous transition metal oxide structures with large open channels ideal for ion transport. The technique combines two AI tools that together can explore thousands of crystal structures significantly faster than traditional laboratory experiments.
☀️ Now over one million balcony solar installations in Germany
Germany now has over one million balcony solar installations in operation producing environmentally friendly energy. The installations together deliver almost 1 gigawatt of power, equivalent to 956 megawatts.
☀️ Solar energy with batteries now delivers electricity around the clock in several countries
17 kWh battery storage is enough to convert 5 kW solar panels into constant 1 kW clean electricity around the clock. Sunny cities like Las Vegas can reach 97 percent of the way to constant solar electricity every hour throughout the year.
🏭 South America the first continent without planned new coal power plants
South America has become the first continent in the world without planned new coal power plants, after having 18 projects on the drawing board in 2015. Renewable energy sources have become economically superior to coal across the continent.
🔋 Denmark's first molten salt battery can power 100,000 homes for 10 hours
Denmark has launched a 1 GWh molten salt battery that can store renewable energy for up to two weeks with minimal loss. The system uses industrial byproducts from chlorine production and achieves 80-90 percent efficiency for co-generation of heat and electricity.
