The climate problem is getting worse, but the solutions are getting better.  So far, no technology has done more to improve the solutions available to address climate change than solar photovoltaics (PV).  This revised edition describes an array of driving forces leading us toward a solar-centric energy system, one where solar power lies at the core rather than at the edge.  ...

Biography

Gregory F. Nemet is a Professor at the University of Wisconsin–Madison, USA, in the La Follette School of Public Affairs, where he recently served as Interim Director.  He holds the Salzwedel Distinguished Faculty Chair in Business and Regulation and is also a Vilas Distinguished Achievement Professor.  He was awarded the inaugural World Citizen Prize in Environmental Performance by APPAM in 2019.  He was a Lead Author for the Intergovernmental Panel on Climate Change’s 6th Assessment Report (2023).

“Gregory Nemet brings new insights to his definitive study on the solar technology revolution.  Solar is cheap, Nemet documents in detail, because it became a global technology—a warning to policy makers who are pushing nationalism without regard for how it will undermine technological innovation and solving problems like climate change.”

 

—          Prof. David Victor, University of California San Diego

 

 

“It is rare for a book to aim so explicitly at explaining one of the fundamental transformations of the age; it is rarer still for one to succeed in that aim. Greg Nemet’s ‘How solar energy became cheap’ is one of those rarest of books. And as if that were not enough, it does so clearly and in a way useful not only to those seeking to understand today’s world, but also to those seeking to improve tomorrow’s. If the fight against climate change is to stand a chance, many other technologies need to achieve solar-like growth. This book has important lessons for how that can be done. It is indispensable.”

“Gregory Nemet brilliantly describes how solar became cheap. Now it is time to transfer this solar success story to all types of renewable energy and other technologies to bring carbon dioxide concentrations back to pre-industrial levels.  This is the path to the survival of human civilization, for which Gregory Nemet provides important suggestions.”
