     View Summary

    <p>In Japan, a large share of final energy demand is used for hot water and space heating and cooling in buildings. Therefore, it is important to consider how to meet the heat demand of residential and commercial sectors. Despite the potential benefits of renewable heat technologies, little study has been done to examine the effects of the introduction of them. The objective of the present study is to develop an input-output model for assessing environmental and socio-economic impacts of renewable heat technologies from a life cycle perspective. The developed input-output model covers three renewable heat systems, namely, solar thermal, ground source heat pump and wood boiler systems. Conventional heat systems are also considered for comparison purposes. The new 37 sectors are created and added to the Japanese input-output table for the year 2011. This study employs a mixed-unit input-output model. The output of the operation sectors is expressed in physical terms instead of monetary terms. Building thermal simulation software is used to calculate heat load. We conduct employment impact assessment using the developed input-output model. The results indicate that the introduction of renewable heat technologies induce employment shifts away from the fossil fuel-related sectors towards renewable sectors.</p>

  • Effects of Daily Intervention on Psychological Proximity to Photovoltaic Systems

    Proceedings of the Annual Conference of The Japan Institute of Energy ( The Japan Institute of Energy )  28 ( 0 )   294 - 295   2019.08

    Joint Work

     View Summary

    <p>This study focuses on the possibility of promoting pro-environmental behavior by improving psychological proximity to photovoltaic (PV) systems. An intervention experiment is carried out using a digital signage at a nursery school where PV systems are installed, and pre- and post-questionnaire surveys are conducted to evaluate the influences of the intervention. Statistical analysis of questionnaire surveys suggests that the intervention should have effects on improving psychological proximity and promoting pro-environmental behavior.</p>

     View Summary

    <p>The present study assesses the possibility of spreading renewable power generation using a bottom up linearprogramming model for energy system analysis. The results reveal that an increase in the installed capacity is expected for offshore wind power generation, wave energy conversion, ocean thermal energy conversion and geothermal power generation when considering their co-benefits such as employment creation effects.</p>

  • Prediction of CO2 emission by renewable energy generation

    Proceedings of the Annual Conference of The Japan Institute of Energy ( The Japan Institute of Energy )  28 ( 0 )   202 - 203   2019.08

    Joint Work

     View Summary

    <p>Renewable energy generation is zero emission technology. However, CO<sub>2</sub> emission of renewable energy generation plants is emitted from construction stage. We have been conducted analysis of CO<sub>2</sub> emission on construction of renewable energy generation apparatus per generated power. Now, the share of renewable power generation is expected to increase towards CO<sub>2</sub> emission reduction targets. In the near future, renewable power plants will be manufactured using electricity generated from renewable energy sources, so CO<sub>2</sub> emissions per unit of electricity generated will be lower than present levels. In this study, renewable energy power plants calculated the potential for CO<sub>2</sub> emission reduction per generated power using LCA. We used scenarios of 2030 (30% decreased by METI) and 2050 (80% decreased by RITE) in our calculations. Electricity ratio per total CO<sub>2</sub> emission of PV, wind power, wave power, tidal power generation, and ocean thermal energy conversion is calculated as 32%, 21%, 20%, 21% and 14%. CO<sub>2</sub> emissions reductions per electricity generated from renewable energy generation averaged 6% in 2030 and 17% in 2050.</p>

    Introduction and explanation (scientific journal)   Single Work

     View Summary

    <p>This paper concisely reviews a variety of methods for technology assessment in a wide range of fields and points out that technology assessment is a multi-tiered concept. The word "technology assessment" was born in the United States of America in the 1960's and then many methods for assessing technologies have been developed and implemented. The concept of technology assessment is composed of three elements: assessment of engineering characteristics of technology, assessment of social characteristics of technology and assessment of social values of technology. A better understanding of the concept of technology assessment provides a chance to discuss what type of technology assessment is required and what role it should play towards creating a sustainable society.</p>
