Chinese carmaker Changan Automotive is preparing to release what it describes as the world’s first mass-produced passenger EV powered by a sodium-ion battery. The model is the Changan Nevo A06, and on paper it reads like a practical everyday sedan. It carries a 45kWh battery pack and is expected to deliver over 400km of range […]
Residential buildings are often overlooked in discussions about energy-positive design. Individually, their impact seems small. Collectively, housing represents one of the largest sources of energy demand in cities. Completed in Shenzhen in 2024, the Positive Energy House by People’s Architecture Office shows how residential architecture can generate surplus energy through design-led integration, not technological excess. […]
HYBARI remains Japan’s first hydrogen-powered test train and a key step toward low-carbon rail transport. The name stands for Hydrogen Hybrid Advanced Rail Vehicle for Innovation. JR East developed the train in collaboration with Toyota and Hitachi. Officially called the FV-E991 series, it is a two-car prototype powered by a hydrogen fuel cell combined with […]
Lib Earth House Model B is one of Japan’s most forward-looking residential prototypes. Completed in 2025 by Lib Work, it was designed as a model for low-carbon residential construction. The project uses a cement free mix of soil, lime and natural fibres that can be 3D printed into curved walls. This approach reduces the carbon […]
Japan has opened one of the most promising osmotic power plants to date. The new Fukuoka facility uses the natural difference between saltwater and freshwater to generate clean electricity. Engineers call this salinity-gradient power. It is sometimes known as blue energy. The world’s first osmotic power plant opened in 2009 in Tofte, Norway. Built by […]
Often cited as one of the world’s most sustainable travel destinations, Costa Rica has spent decades aligning environmental protection with economic development. Nearly all of its electricity is generated from renewable sources, and around a quarter of the country’s land is protected as national parks, biological reserves, and wildlife corridors. This long-term commitment has shaped […]
Japan’s northernmost island, Hokkaido, is often associated with snow-covered landscapes, wide open plains, and a slower pace of life. Beyond its dramatic scenery, the region has quietly emerged as one of Japan’s most compelling examples of how sustainability, community, and nature can coexist. From protected wilderness and indigenous traditions to renewable energy innovation, Hokkaido shows […]
Researchers at The Hong Kong Polytechnic University, led by Yin Jun, have reached a major milestone in solar energy research. Their latest perovskite/silicon tandem solar cells are now approaching 40 percent efficiency, meaning nearly 40 percent of incoming sunlight can be converted directly into electricity. This figure represents a significant leap beyond conventional silicon solar […]
Renewable energy is growing rapidly worldwide, but one persistent question remains: what happens when the sun is not shining or the wind stops blowing? Solar panels and wind turbines are excellent for producing clean electricity, but they are intermittent. To maintain a reliable, continuous power supply, engineers and researchers are exploring three complementary technologies: battery […]
