This new, developing device works to both heat and cool the area around it without fossil fuels. (Credit: Linda Cicero, Stanford News) As people search for solutions to the climate change crisis on Earth, scientists are working to create renewable energy sources as alternatives to fossil fuels. Now, scientists at […]

That’s no moon… China is planning to replace streetlamps with light from an ‘artificial’ moon China is planning to launch its own ‘artificial moon’ by 2020 to replace streetlamps and lower electricity costs in urban areas, state media reported Friday. Chengdu, a city in southwestern Sichuan province, is developing “illumination […]

Another problem that besets today’s refrigeration systems is that most coolants cause environmental and health damage. A novel […]

Credit: CC0 Public Domain Europe’s decision to promote the use of wood as a “renewable fuel” will likely greatly increase Europe’s greenhouse gas emissions and cause severe harm to the world’s forests, according to a new paper published in Nature Communications. European officials on final language for a renewable energy directive earlier this […]
