Building America's Energy Future - A Portfolio of Promising Policies

June 24, 2013

NEPI has crafted a report that quantifies an aggressive target by 2035 to reduce oil use and greenhouse gas emissions. It shows how a set of five policies can achieve these goals at a surprisingly low cost and will enhance our national security, create a healthier environment, and take a significant step toward mitigating climate change. An Executive Summary of the report is also available.

The Economics of Fuel Economy Standards versus Feebates

April 24, 2013

In this paper Ken Gillingham elucidates the relationship between fuel economy standards and “feebate” policies that penalize low fuel economy vehicles with a fee and reward high fuel economy vehicles with a rebate. The analytical results show how a feebate can be designed to exactly match a fuel economy standard, both under the previous regulation and the current regulation.

Consequences of U.S. Dependence on Foreign Oil

April 24, 2013

This paper examines the consequences of U.S. dependence on foreign oil. Stephen P. A. Brown and Ryan T. Kennelly quantify the costs of U.S. dependence on foreign oil using a relatively broad metric that is based in a long-standing economics literature and a relatively narrow metric that is confined to oil-security externalities as defined by Brown and Huntington (2013).

What Set of Conditions Would Make the Business Case to Convert Heavy Trucks to Natural Gas? – a Case Study

May 2, 2012

In our 2010 study with Resources for the Future, NEPI identified the use of natural gas for heavy trucks as a promising way to displace petroleum use. In this new paper, we asked Anna Lee Deal to explain what would make the business case for a truck fleet operator to make the switch from diesel to natural gas.

Organizations under Large Uncertainty: An Analysis of the Fukushima Catastrophe

October 7, 2011

In this NEPI Working Paper, Masahiko Aoki and Geoffrey Rothwell of Stanford University present an analysis of the organizational (industry and government) responses to the Fukushima nuclear catastrophe, and make policy recommendations to address the systemic weaknesses that exacerbated the direct impacts of the earthquake and tsunami on the nuclear facility.

Energy Efficiency in the Residential and Commercial Sectors

January 31, 2011

In this paper, Max Auffhammer and Alan Sanstad review the history and results of public policies to promote the diffusion of energy-efficient technology for providing energy services in residential and commercial buildings and of prospective estimates of future energy consumption reductions that might result from their expansion.


Residential Retrofit Ground Source Heat Pump Benefits Assessment

September 15, 2010

Xiaobing Liu assesses the energy savings, CO2 emissions reductions, reduction in peak electrical demand,
and utility cost reductions, from retrofitting all U.S. single-family homes that have space heating, space
cooling, and water heating equipment with state-of-the-art GHP systems.


Hybrid Vehicles and Policies to Reduce GHG Emissions

July 15, 2010

Virginia McConnell (Resources for the Future) and Tom Turrentine (Center for Transportation Studies, University of California-Davis) assess the impact of hybrid, plug-in hybrid, and electric vehicles on emissions and oil consumption, along with the cost-effectiveness, of several policies specifically targeted at encouraging the deployment of these vehicles.

Economics, Energy and GHG Implications of LNG Trucks

June 23, 2010

Alan J. Krupnick explores how changes in fuel price differential (between natural gas and diesel), first-cost differential, and interest rate may affect the economic potential of LNG trucks, and also examines the effects on oil consumption of imposing a mandatory penetration rate of LNG trucks in the heavy-duty fleet.


Reassessing the Oil Security Premium

June 23, 2010

Stephen P. A. Brown and Hillad G. Huntington quantify several of the economic losses associated with oil supply disruptions, taking into account projected world oil market conditions, probable oil supply disruptions, the market response to oil supply disruptions, and the U.S. economic losses resulting from disruptions to the extent they that should be considered externalities.
