Clean energy won’t save us from the effects of climate change.
Amid corporate Net Zero campaigns, the politics of the Green New Deal, and the calls to abandon fossil fuels for renewable technology — or vice versa — lies a troubling truth: No clean technological solutions can solve the problem of human-induced climate change.
To find a credible path to a sustainable future, we must set aside hopes of building our way out of humanity's addictions to energy and material convenience. In Why We Struggle to Go Green: Hard Truths about the Clean Energy Transition (Texas A&M Press, 2025), Tom Ortiz offers a clear-eyed assessment of our efforts to mitigate the effects of climate change. As a mechanical engineer who has traversed the conventional and renewable energy landscapes for 30 years, Ortiz provides an in-depth yet easy-to-understand assessment of the harsh reality facing mankind.
Bridging the gap between academic research and journalism, Ortiz shows why there are no easy answers in the energy transition. Beginning with a general overview of human energy use and a summary of key physical constraints on energy and natural resource extraction, the book details five pillars of the transition: electrification, carbon capture and storage, hydrogen, recycling, and carbon pricing. Ortiz concludes with recommendations for changes society can make that, while perhaps painful and controversial, will reduce our collective environmental impact and bequeath a more manageable legacy to future generations.
Why We Struggle to Go Green cuts through the hype and rhetoric to offer something rare: climate change realism from someone who’s spent decades looking for solutions.
