German government study to evaluate potential of floating solar on lakes at former mines

Around 500 open-pit lakes left behind as a legacy of Germany’s open-cast lignite mining industry could potentially host more than 50 GW of solar generation capacity. With that in mind, the Federal Ministry for Economic Affairs and Energy is financing a three-year study into the technology’s revenue potential. The German government will fund a research […]

New cathode design promises battery sustainability

Scientists in the U.S. developed a new cathode design for lithium-ion batteries that they say could open up a range of different materials for further research. The group has high hopes that the discovery can quickly be brought to scale, easing some of the growing concerns around supply chains for battery materials. Energy storage has […]

Could agrivoltaics feed our demand for clean energy?

Could Agrivoltaics Feed Our Demand For Clean Energy

Could agrivoltaics feed our demand for clean energy? Agrivoltaics could result in more food, more energy, lower water demand, lower carbon emissions, and more prosperous rural communities, says an Oregon State University researcher. He plans to build a farm to prove the point.     Using land for both solar photovoltaic power and agriculture could […]

What is distributed generation’s real worth for the grid?

What Is Distributed Generation’s Real Worth For The Grid

What is distributed generation’s real worth for the grid? A thought experiment by UC Berkeley energy economist Severin Borenstein suggests how much rooftop solar could reduce transmission and distribution costs in the United States.     California and other locations are moving to renewable energy at high speed. But even in these forward-leaning areas, there […]
