    Measuring Energy Intensity in Japan: a New Method
    (Elsevier, 2017) Zaim, Osman; Gazel, Tuğçe Uygurtürk; Akkemik, K. Ali
    Energy intensity and energy conservation have been important pillars of energy policies in Japan. Recently the government has introduced new initiatives to enhance energy efficiency and reduce energy intensity. We analyze the energy intensity in Japan for the period 1973-2006 by proposing a new method which takes into account all other inputs used in production and corrects for the bias in the traditional energy intensity measure. We show that the traditional energy intensity measure has serious flaw. The traditional measure overestimates actual energy intensity before the mid-1980s and largely underestimates afterwards. It is found that aggregate energy intensity has risen remarkably from 1991 to 2001. The main cause of this rise is the rapid rise in energy intensity in manufacturing and energy sectors.

    Multidirectional Relationship Between Energy Resources, Climate Changes and Sustainable Development: Technoeconomic Analysis
    (Elsevier, 2020) Ucal, Meltem Şengün; Xydis, George
    Global changes in temperature will likely change energy use and electricity production capacity. Considering the relationship between climate change and energy resource use, changes in temperature and the frequency and intensity of extreme events will affect how much energy is produced and consumed. The green economy and green growth are located at the heart of the fight against climate change in creating sustainable development. This paper considers the multidirectional relations between climate change, energy resources, and sustainable development including the perspective of a green economy via a technoeconomic analysis. A link among energy resources, climate changes and sustainable development has been displayed via a technoeconomic analysis in the case study, which was focused on taking into consideration the needs of the hydroponic units, the product selling price, the electricity price of the wind farm (WF), and at the same time the energy demand, under a nexus approach. Via the technoeconomic analysis, it was proven that moving on to smaller investments of 2 MWs is more efficient compared to larger projects e.g. 18 MWs, however, this cannot be considered immediately as the preferred solution since it is always a matter of impact on the local society.

    The Role of Trade and Fdi for Co2 Emissions in Turkey: Nonlinear Relationships
    (Elsevier, 2019) Haug, Alfred Albert; Ucal, Meltem Şengün
    This paper examines the effects of foreign trade and foreign direct investment (FDI) on CO2 emissions in Turkey. We consider linear and nonlinear ARDL models and find significant asymmetric effects of exports, imports and FDI on CO2 emissions per capita. However, FD1 has no statistically significant long-run effects. In the long run, decreases in exports reduce CO2 emissions per capita but increases in exports have no statistically significant effects. Increases in imports push up CO2 emissions per capita, while decreases in imports have no long-run effects. On the other hand, CO2 intensity, which measures CO2 emissions per unit of energy, is not influenced by exports and imports, nor by FDI. Instead, it is affected positively by financial development and urbanization. Also, we find that an environmental Kuznets curve is present for both CO2 measures so that increases in real GDP per capita have led to reductions in CO2 emissions for at least the most recent decade, controlling for other confounding factors. Furthermore, the sectoral shares of CO2 emissions in total CO2 emissions change asymmetrically with foreign trade for two of four sectors, with export increases leading to lower CO2 shares and imports having the opposite effect.
