An empirical study of willingness to renewable energy installation using importance-performance analysis: the case of Taiwan

Global warming and climate change issues, coupled with excessive energy consumption, has already had dramatic effects on the survival of the human race. To support electricity generation from renewable sources, most governments have instituted different mechanisms to raise the investment incentive to renewable energy. Past researches mainly focused on evaluation of energy conservation. However, few researchers studied in characteristics of renewable energy installers' willingness. Due to Importance-performance analysis (IPA) is ease of application, this study utilizes IPA based on the respondents' perception to explore which factors, including administrative support and governmental reward policy to renewable energy installation, and provide valuable information for government energy policy decision-makers. The study shows that the government urgently to solve administrative support includes eliminating regulatory barriers, setting a cross-ministry supporting, enhancing administrative efficiency; in addition, governmental reward policy measures need to be resolved to include reasonable acquisition rates, and effective incentive policy for R&D.
