Development of Expository Texts on Biomass Power Generation

概要 （図表や脚注は「報告書全文」に掲載しております）

我が国では，再生可能エネルギー電源の普及促進のために，RPS制度やグリーン電力プログラムが実施されている．消費者がこれらの施策の是非を判断する際には，再生可能エネルギー電源に関する正確な理解が不可欠であり，行政や電気事業者は，消費者の理解に資する情報を的確に伝える事が求められている．そこで，前報において，メンタルモデル・アプローチを適用して，バイオマス発電に関する提供すべき情報内容を抽出した．本研究では，前報の結果に基づき三百文字程度のバイオマス発電の説明文案を作成し，それに対する評価のための質問紙調査を実施した．その結果，提供すべき情報内容から構成される説明文に対する全般的な評価は肯定的であったが，カーボンニュートラルな特性(CN特性)の説明は不十分となる可能性が明らかとなった．そこで，分析結果に基づき，CN特性に関する修正文案を提案した．

概要 （英文）

In order to promote production of electricity from renewable energy sources (RES-E), support schemes have been implemented, such as the Renewables Portfolio Standard and green power programs. When people consider and judge costs and benefits associated with those schemes, they need to know the characteristics of RES-E correctly. In our previous research, we identified the contents of information to be provided for people to enhance their understanding of biomass power generation (BPG), such as a) definition, b) specific resources, c) characteristics of power generation technologies, d) sustainable availability of resources, e) the carbon neutral (CN) concept, f) high generation costs, and g) no disturbance to food prices in Japan.
The objective of this study is to develop short expository texts on BPG. Firstly, we developed two types of expository texts containing approximately 300 characters. One is the text composed of seven contents identified in our previous research results (the basic type). Another text focuses on the CN concept accompanied with definition, resources, and generation technologies (the CN type). Secondly, we analyzed data collected through a questionnaire survey of 4083 respondents to have them evaluate the expository texts we created. Approximately 90 percent of respondents regard the basic type of text as understandable and useful for their understanding of BPG. Over two thirds of respondents think contents of sustainable availability of resources, generation costs, and no disturbance to food prices understandable and convincing. Only half of respondents, however, are convinced with the CN concept described in the basic type, while two thirds of respondents are convinced with the CN concept in the CN type. Finally, on the basis of survey results, particularly the reasons why respondents are not convinced with the CN concept, we developed modified texts of the CN concept for the basic type a little longer than the original text.
