With interest in topics such as climate change, energy security, and alternative energy sources being at an all-time high, the effects of today's decisions now rest on the shoulders of future generations. There are no easy answers to our energy issues, so costs and benefits must be considered when evaluating all energy alternatives; alongside that, prices must be right and need to reflect the full social costs to society of a given source of energy. Energy Economics outlines the fundamental issues and possible solutions to the challenges of energy production and use, and presents a framework for energy decisions based upon sound economic analysis. It considers market forces and policy goals, including economic prosperity, environmental protection, and other considerations that affect societal well-being. This book focuses on both energy choices and the impact of these choices on market performance, environmental conditions, and sustainability. The initial section covers the fundamental economic concepts for analyzing energy markets. Following this, a detailed analysis of established energy sources, specifically fossil fuels and nuclear energy, leads into consideration of energy alternatives such as renewable energy and next-generation alternatives. Electricity production and regulatory trends are covered in depth. The final section considers policy: environmental considerations, sustainability, and energy security. The concluding chapter is a comprehensive vision for our energy future. Drawing on current energy headlines, perspectives familiar from the popular press, and views outside economics, this text sharpens students' ability to understand, evaluate, and critique policy using appropriate economic analysis. The text builds a foundation that culminates in a view of a comprehensive energy policy that improves upon the vacillations of past decades.

This study contains a simulation of a coal‐fired electric plant subject to multiple pollutant standards for SO2 and NOx. It shows that firms may not choose the lowest cost technology. The firm's cost‐minimizing choice is compared for three increasingly stringent standards: the 1990 Clean Air Act Amendments, the 1997 New Source Performance Standards, and the 2002 North Carolina Clean Smokestacks Act. The study finds support on cost‐benefit grounds for the 2002 North Carolina standard, which is the most stringent standard, but not for the 1997 NSPS. (JEL Q28, Q25, L94)

In the aftermath of Fukushima, decisions to slow or stop the future use of nuclear power have not been based on rational economic analysis. We find that there are cost‐effective technologies that would greatly mitigate future natural disasters. Even if the U.S. nuclear industry adopted new safety technologies and paid the full cost of insurance and borrowing, it is more efficient to continue to use existing nuclear plants than to replace them with new fossil fuel plants. However, new nuclear plant costs can exceed fossil fuel alternatives if the price of carbon emissions is below $118/ton. (JEL Q40, Q48, Q54)

Abstract
We develop a model of the household that includes pets. We use over twenty years of data from the Consumer Expenditure Survey to consider pet ownership and expenditures for single and married households. Households with very young children are less likely to own pets and have lower pet expenditures, showing a substitute relationship. Households with older children are more likely to own pets, suggesting a complementary relationship. However, households with more children show reduced pet spending, evidence of a substitute relationship. Surprisingly, when the effect of income on pet ownership and pet spending are jointly considered in computing the income elasticities, women in married households have smaller income elasticities for pet expenditures than do men. This finding is the opposite of what has been found for women and men with regard to expenditures on children.

Using data from Charlotte, NC, a New South city without a legacy of heavily contaminated properties, we find the distance from unremediated brownfields—typically former industrial properties believed to have modest contamination—to have no effect on residential sales values, but proposed cleanup and actual remediation have positive, substantial, and significant effects especially within 0.5 miles of the brownfield. Our results are consistent whether we examine all property values within a given distance, such as 0.5 miles, or examine discrete distances, such as 0.3–0.5 miles. An estimate of the benefits is on the order of $4 million. (JEL Q51, Q24, Q28, R52)
