Abstract: This is the first academic paper that reviews the economic, policy, and technology history of shale gas development in the United States. The primary objective of the paper is to answer the question of what led to the shale gas boom in the United States to help inform stakeholders in those countries that are attempting to develop their own shale gas resources. This paper is also a case study of the incentive, process, and impact of technology innovations and the role of government in promoting technology innovations in the energy industry. Our review finds that government policy, private entrepreneurship, technology innovations, private land and mineral rights ownership, high natural gas prices in the 2000s, and a number of other factors all made important contributions to the shale gas boom.

Abstract: Several recent studies have used simulation models to quantify the potential effects of recent environmental regulations on power plants, including the Mercury and Air Toxics Standards (MATS), one of the US Environmental Protection Agency’s most expensive regulations. These studies have produced inconsistent results about the effects on the industry, making general conclusions difficult. We attempt to reconcile these differences by representing the variety of assumptions in these studies within a common modeling platform. We find that the assumptions, and their differences from the way MATS will be implemented, make a substantial impact on projected retirement of coal-fired capacity and generation, investments that are required, and emissions reductions. Almost uniformly, the actual regulation, when examined in its final form and in isolation, provides more flexibility than is represented in most models. We find this leads to a smaller impact on the composition of the electricity generating fleet than most studies have predicted.
