Less Carbon, More Chill Novel Refrigeration Approach Uses PCMs To Freeze, Cool Perishables

A technology developed by Oak Ridge National Laboratory works to keep food refrigerated with phase change materials, or PCMs, while reducing carbon emissions by 30%. More than 100 million household refrigerators in operation across the United States consume up to 2 kilowatts of electricity daily. These refrigerators contribute to energy … [continued]

Insurance Companies: Consider Climate Risk Events As “Constant Threats” — CleanTechnica Exclusive

In the US, climate risk events are occurring more frequently in places where development was once deemed safe but now is larger than initially anticipated. Insurance is one of the non-environmental systems that enables us to live our daily lives with the knowledge that our property is protected. Up until … [continued]

Electricity From Carbon Dioxide

When I first read about the work of the University of Queensland research team claiming to create electricity from CO2, my initial thought was that this was a cross between a fossil fuel funded beatup and a fairytale. But, digging deeper, and talking with Dr Zhuyuan Wang of UQ’s ARC … [continued]

Graph: U.S. Energy-Related CO2 Emissions Decreased by 3% in 2023

Based on analysis in our most recent U.S. Energy-Related Carbon Dioxide Emissions report, U.S. energy-related CO2 emissions decreased by 3%, about 134 million metric tons (MMmt), in 2023. Over 80% of the emissions reductions occurred in the electric power sector, caused largely by decreased coal-fired electricity generation, which was displaced by increased generation … [continued]
