President-elect Donald Trump has vowed to cut support for clean power. Two guests from Bloomberg NEF weigh the likely impacts on clean energy development. --- President-elect Donald Trump has vowed to reduce federal support for clean power as soon as he takes office in January. Yet political realities may limit the extent to which incentives, such as those in the Inflation Reduction Act, may be ro...

Byzantine governance structures and vested interests are slowing the greening of the U.S. electrical grid. Two grid policy experts discuss paths forward. --- The U.S. electrical grid faces declining reliability, often attributed to a rapidly evolving energy mix, surging demand, and more frequent severe weather. Yet a deeper issue lies in the fragmented governance of the grid, where conflicting vis...

Carnot Prize recipient Jacqueline Patterson explores how the clean energy transition can drive meaningful progress toward energy and climate justice. --- In 2009 Jacqueline Patterson became the founding director of the NAACP’s Environmental and Climate Justice Program. It was a role that Patterson, who’s this year’s recipient of the Kleinman Center’s Carnot Prize, had expected to be short lived: s...

Kleinman Center visiting scholar Kirsten Jenkins explores the concept of a just energy transition, and why it must be expanded beyond its labor roots to address broad energy system injustices. --- The term “just transition” has its roots in organized labor movements, and has traditionally referred to the idea that workers in the fossil fuel economy must find security in the green energy economy of...

Virtual power plants can help electric grid operators address supply shortages and reliability concerns, but policy support is needed. --- The U.S. electrical grid is under growing stress, raising concern that recent widescale power outages may signal more grid challenges to come. In recent years, electricity demand has grown at an accelerating pace while, at the same time, power supply has tighte...

David Spence explores the rise of identity politics in the U.S. and how it has fueled bitter partisanship over the transition to clean energy. --- Throughout American history, opposing political parties have at times set aside their differences to create “republican moments”— periods of bold, bipartisan action to address critical challenges.  Today, such moments may seem unlikely, yet the need for...

Nvidia’s director of accelerated computing, and a Penn expert in AI and datacenters, explain why AI uses so much energy, and how its energy appetite might be curbed. --- Artificial Intelligence is taking off.
