This is the first full-length comparative study of the national renewable energy laws of every country in the world. Crossley provides a global understanding of how and why different countries support the accelerated deployment of renewable energy and asks whether these laws are converging globally or subject to regulatory competition.

1. Introduction PART Ⅰ. What is renewable energy? A case of conceptual consensus 2. The renewable energy sources used for electricity generation consensus PART Ⅱ. Why do countries intervene in the renewable energy sector? A case of normative divergence 3. The economic justification for regulating renewable energy 4. Why do countries legislate to accelerate the deployment of renewable energy PART Ⅲ. What role do regulatory support mechanisms play in national renewable energy laws? A case of substantive divergence 6. The future developmnet of regulatory support mechanisms-unification, harmonisation, convergence, divergence or regulatory competition? 7. Conclusion Index
