Carbon-Free Energy Deepens Penetration in North America
The transition from carbon-intensive generation to clean and renewable energy is picking up the pace in the United States, finds DNV GL’s latest Energy Transition Outlook report. However, unlike many other regions, the transition is being driven sub-nationally by cities, states, and corporations due to the lack of supportive federal regulations. The way the energy transition is unfolding in the U.S. is the result of market forces and technological developments and costs, rather than governmental mandates. Cities and states are front-line players in the energy transition. States like New York, California, and

AI may Help Scientists Make Spray-on Solar Cells

UCF's Jayan Thomas led the team in reviewing more than 2,000 peer-reviewed publications about perovskites and collecting more than 300 data points that were fed into the AI system the team created. The system was able to analyze the information and predict which perovskites recipe would work best.

Artificial Intelligence may be just the thing to accelerate spray-on solar cell technology, which could revolutionize how consumers use energy. A research team at the University of Central Florida used Machine Learning, aka Artificial Intelligence to optimize the materials used to make perovskite solar cel
