Researchers and professional evaluators are increasingly turning to randomized field experiments to evaluate energy efficiency programs and policies. This article provides a brief overview of several experimental methods and discusses their application to energy efficiency programs. We highlight experimental designs, such as randomized encouragement and recruit-and-deny, that are particularly well suited for situations where participation…

Wholesale and retail electricity markets in Japan: Results of market revitalization measures and prospects for the current reform
This study provides an overview of the current status of the wholesale and retail electricity markets in Japan, with a focus on the results of market revitalization policies, such as the thermal power bidding system, regular backup, and partial supply system. This study also offers a perspective on the future of the Electricity System Reform…
Aiming at a Low Carbon Society in Japan by 2050: Impact of the Fukushima Nuclear Accident and CO2 Reduction Target
Since the Fukushima nuclear accident in 2011, Japan has been struggling with its energy and environmental policy, without a clear picture of the future for nuclear power. The Government of Japan released its latest Strategic Energy Plan in April 2014, and announced its CO2 emissions target (24% reduction by 2030 compared to 2005 levels) and…

An ex-ante evaluation of the EU Energy Efficiency Directive – Article 7
The European Union’s Energy Efficiency Directive calls for EU Member States to put in place ambitious energy efficiency policies and requires them to establish energy saving targets. One of the most important Articles of the Directive is Article 7, which required Member States to implement Energy Efficiency Obligations and/or alternative policy instruments in order to…
The Effect of Community Reinvestment Funds on Local Acceptance of Unconventional Gas Development
A survey with an embedded experimental design is employed to determine whether local public support for an unconventional gas development (UGD) project is influenced by a policy that commits a portion of private revenues from UGD to the state or local government. The public opinion survey (N = 2,700) oversamples residents living in counties of…
Electricity market reform in Japan after Fukushima
This study reviews the status, progress, and policy issues related to the reform of the Japanese electricity market undertaken in response to the disaster at the Fukushima nuclear power plant in March of 2011. The reform has three stages: (1) establishment of a neutral organization of network operation, (2) extension of retail competition to household…
Minimum Energy Efficiency Standards for Appliances: Old and New Economic Rationales
We revisit Hausman and Joskow (1982)’s economic rationales for appliance minimum energy efficiency standards. In addition to the four market failures they argued could justify appliance standards – energy prices below marginal social cost, consumers underestimating energy prices, consumer discount rates above social discount rates, and principal-agent problems – we discuss two additional market failures…
Electricity demand response in Japan: Experimental evidence from a residential photovoltaic power-generation system
We report on a randomized controlled trial used to examine the effect of dynamic pricing when applied to households with rooftop photovoltaic (PV) power-generation systems. Using high-frequency data on household-level electricity use, PV generation, purchases, and sales, we find that critical peak pricing induced significant usage reductions of 3-4% among households with PV systems, a…
Time for Tough Love: Towards Gradual Risk Transfer to Renewables in Germany
After more than a decade of supporting renewable energies (RE) through feed-in tariffs, Germany has set out to integrate RE into the power market. This requires RE investors to carry market risks, in particular the power price risk. But under the current financial structure higher risks would negatively impact the bankability of new projects, which…
