The electricity market, technologies and policies are transforming as rapidly as wireless telecommunications changed the ways that we live and work.  In this seminar, we will learn about and discuss how legal and policy principles are adapting to emerging distributed clean solar energy and battery storage technologies and a more competitive and decentralized electric power market.  We will engage in simulations and role plays to better understand how dynamic energy law and policy issues are addressed in the regulatory and political arenas. We will explore newly emerging "clean energy law" and "environmental constitutionalism" as federal courts increasingly review, for the first time, the constitutionality of federal and state environmental and energy statutory standards.  For example, what are the limits under the Commerce Clause, Supremacy Clause and the 10th Amendment on federal actions to encourage state clean energy and environmental policy actions, and in what circumstances should there be federal preemption of states' energy policy initiatives?   Do the Commerce Clause and the Supremacy Clause affect state standards for new renewable energy development, and state subsidies for otherwise uneconomic old nuclear power plants to keep running?  Can a state enact a renewable energy standard requiring utilities to purchase a percentage of their electricity supply from wind power and solar energy AND specify that those resources be principally provided from in-state generators?  What are the constitutional and statutory lines of demarcation between the Federal Energy Regulatory Commission's and state Public Utilities Commissions' regulatory authority for transmission siting and pricing, and for energy efficiency and demand response? What challenges are presented by a federal system of government, based on state boundaries, in regulating energy generation, which produces commodities (i.e., electrons) and pollution that cross those boundaries?  What are the benefits versus risks and harms of inconsistent standards in Justice Brandeis' "fifty laboratories of democracies"? The common law has always been the remedy of last resort -- the bulwark of legal theories upon which laws are based and looked to when legislatures or policymakers have not addressed a specific issue.  Is the common law a viable approach to addressing climate change in the first place, and what room does the U.S. Supreme Court's AEP decision leave open for state common law claims?  What role, if any, should there be both for the federal and state common law of public nuisance?  What's the difference?  Why does it matter if federal common law remedies are displaced if the state common law remedies are not displaced and can continue to be asserted by plaintiffs?  Is the common law a prod, a solution, or both? This seminar will take place in "real time" while: (1) There is rapidly developing new energy case law with decisions issued by the United States Supreme Court and other courts in this area of emerging law; (2) Market forces and technological innovations -- rapidly improving distributed solar energy and energy storage, robust wind power, low-priced shale gas, and more energy efficient lighting, appliances and equipment -- are reshaping traditional energy markets and putting new economic pressures on aging baseload coal and nuclear plants; (3) The Trump Administration is moving to fundamentally change environmental and energy policies, but the federal Production Tax Credit for wind power and Investment Tax Credit for solar energy remain in force; (4) State and municipal governments are moving to implement clean energy development policies and innovative financing approaches; and (5) The private sector is accelerating investments in cleaner energy developments and strategies. One key opportunity and challenge for our society and government policymakers at all levels is how to construct policies that support bot
