The second edition of Alternative Energy: Political, Economic, and Social Feasibility builds on the first edition, but with significant updates on dramatic changes within the renewable energy sector over the last decade. Christopher Simon discusses the basic technical aspects of major renewable energy systems and technological developments and considers the impact of politics on energy policy using contemporary theories of public policy—such as, Advocacy Coalition Framework (ACF), Punctuated Equilibrium (PE), Narrative Policy Framework, and Policy Diffusion—as well as discussing the evolution of the social feasibility of renewable energy. The author expands his discussion of alternative energy solutions to consider nuclear power developments and feasibility in the post-Fukushima policy environment. International commitment to renewable energy is also addressed.
