A study has considered the best mathematical models for predicting solar module performance under varying conditions. January 22, 2020Emiliano Bellini A new study has evaluated the accuracy of mathematical models used in the PV industry and research to evaluate the performance of solar modules under varying environmental conditions such as irradiance and temperature. The findings […]
As the decade of delivery begins, we’re seeing a surge in the number of businesses using “applied futures for sustainability” as part of their efforts in the climate fightback — but what does that mean? How does imagining the multiple possible futures still open to us help focus efforts? Where do we start, why and […]

Cars Published on January 21st, 2020 | by Zachary Shahan January 21st, 2020 by Zachary Shahan Last week’s top stories on CleanTechnica included Andy Miles explaining why Tesla vehicles cut pollution rather than causing more pollution, a rundown of how Tesla’s “full stack disruption” sets it apart from the auto crowd, and yet another comparison […]
Cars Published on January 21st, 2020 | by Cynthia Shahan January 21st, 2020 by Cynthia Shahan Sometimes we don’t realize what noise pollution is until we are far from it. Even noises we don’t pay attention to can be disturbing quality of life more than we realize. Some Tesla Model 3 owners have had issues […]
Joint Filing Says FERC Erred on Multiple Areas and Will Force Customers to Pay More for Fossil Fuels WASHINGTON, D.C. — Today, four national organizations representing the range of clean energy companies in the United States filed a request for rehearing by the Federal Energy Regulatory Commission (FERC) on its order to impose a Minimum […]
NV Energy issued a request for proposals to add new renewable energy projects to its portfolio. This announcement comes on the heels of the Public Utilities Commission of Nevada’s (PUCN) December 2019 approval of 1,190 megawatts of new solar energy and 590 megawatts of battery storage to be built in Nevada and serving customers by […]
