Public utilities regulation is a little known area of the law that has an outsized impact on the world. Energy is a primary driver of human prosperity, but its production and use cause immense threats to life on earth. This course will cover how public utilities came to exist, why and how they are regulated, who can influence their behavior, and why it all matters. With a focus on electricity, a little bit of economics, little bit of science, and a bit more law and policy, students will learn the basics of what goes on at public utilities commissions, who are the players involved, and some of the particular challenges and opportunities here in Hawaii.
