Biomass, a renewable energy source, has been viewed as “carbon neutral”—that is, its use as energy is presumed not to release net carbon dioxide. However, this assumption of carbon neutrality has recently been challenged. In 2010 two letters were sent to the Congress by eminent scientists...

Many countries are tightening passenger vehicle fuel economy standards. The literature on passenger vehicle standards has used structural models to estimate their welfare effects. This paper provides the first empirical evidence on the effects of recently tightened fuel economy standards on...

Efforts to limit cumulative emissions over the next century may be partially thwarted by the responses of fossil fuel suppliers. Current price-cost margins for major reserves are ample, leaving scope for significant price reductions if climate policies reduce demand for fossil fuels through...

Many countries are tightening passenger vehicle fuel economy standards. In assessing the welfare effects of standards, the literature has not properly accounted either for their effects on the rate of technology adoption, or for improvements in vehicle characteristics in the absence of...

The Commodity Credit Corporation (CCC) of the Department of Agriculture has proposed regulations to implement the new Biomass Crop Assistance Program (BCAP). Authorized in the Food, Conservation, and Energy Act of 2008, BCAP is designed to ensure that a sufficiently large base of new nonfood,...

Compared with gasoline engines, diesel fuel engines significantly reduce fuel consumption and greenhouse gas emissions from passenger vehicles, but they emit more nitrogen oxides and other pollutants. Across countries, the market share of diesel fuel engines in passenger vehicles varies from...

Some studies of renewable portfolio standards find that regulations increase generation costs; others find that reduced demand for nonrenewable energy sources lowers natural gas prices and that electricity prices follow. This paper presents reasoning for why these predictions can vary in the...

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...

Some environmental policies focus on emissions intensity rather than total emissions, or they try to mitigate the regulatory impact on the final product market. To analyze the effects of these policies, or to evaluate the distributional effects of any regulation on consumers and producers,...

Electricity markets have typically been regulated all over the world. In Europe, UK and Norway have begun to deregulate their electricity markets. Several more countries will probably join them in the near future, for example Finland, Sweden and Spain. The objectives are twofold: to increase...
