Book excerpt: As of 2017, 69 percent of Americans were in favor of restricting carbon emissions from coal power plants out of concern for climate change and the state of the environment, but can we afford to make the change to cleaner energy sources? This volume looks at the various alternative energy sources and their economic viability, exploring the debate about which path forward makes the most sense. Readers will gain a better understanding of the crossroads facing policymakers and the energy sector and be empowered to form their own opinions about how this urgent issue should be addressed.
