ABSTRACT
The Fukushima nuclear disaster in March 2011 drastically changed the energy consumption
pattern of Japan. Not being able to rely on nuclear energy, the country turned to fossil fuels and
attempted to increase the share of renewable energy in its electricity generation mix. This paper
will explore why geothermal energy is stagnating in Japan, despite the availability of resources
and technologies. The paper first analyzes the various barriers to geothermal energy deployment
in Japan from social, legal, economic, financial and technical viewpoints. The major contribution
of this study is the quantification of the magnitude each barrier and supportive policy has on the
development of geothermal power, with a special focus given to energy finance measures. The
analysis is performed using a Vector Error Correction Model (VECM) using data from 1974 to 2017
and identifies the existence of a long-term relationship between variables, public research and
development expenditures and the Feed-in-Tariff scheme. The latter appears to be the most effi-
cient stimuli to foster geothermal power generation. Subsidies in their current form, on the other
hand, have mixed results both in the long and short term. Environmental concerns and social
opposition appear to be among the major barriers in both the short and long term.
1. Introduction
After the Fukushima-Daiichi nuclear power disaster in March 2011, Japan found itself facing an energy supply crisis. Backlashes
against nuclear energy forced the government to halt nuclear generation. The country first turned to fossil fuels, and in 2014, 88% of
electricity was coming from fossil fuel (Ministry of Economy, Trade and Industry, 2016). As a consequence, Japan’s energy
self-sufficiency fell from a high of 20.2% in 2010 down to 6.4% in 2014 (Ministry of Economy, Trade and Industry, 2016). Taghiza-
deh-Hesary, Rasoulinezhad, and Kobayashi (2016) found that following the Fukushima nuclear disaster and resultant nuclear shutdown,
and due to a higher reliance on fossil fuels, the elasticity of the consumption of most energy sectors concerning oil price fluctuations
reduced, endangering energy security within the country. At the same time, this incident engendered an opportunity for the renewable
energy (RE) sector. The share of RE in the generation mix rose from 9% in 2010 to 12% in 2014 (Taghizadeh-Hesary et al., 2016).
