In this episode of _Unintended Consequences_ from the Cato Institute, Paul and Peter explore how America’s fracking boom, the shift from coal to natural gas, and expanding liquefied natural gas (LNG) markets helped reduce emissions. Drawing on Lipford and Yandle’s recent [article](https://www.cato.org/regulation/fall-2026/can-golden-straitjackets-deliver-good-environmental-news) in _Regulation_ magazine, “Can ‘Golden Straitjackets’ Deliver Good Environmental News,” they examine the environmental and geopolitical benefits of America’s energy transformation, the costs of Germany’s retreat from nuclear power, and how falling solar energy costs are making solar power more accessible.
