Quality Function Deployment-Oriented Strategic Outlook to Sustainable Energy Policies Based on Quintuple Innovation Helix

This study aims to identify the most significant sustainable energy policies by considering quality function deployment (QFD) perspectives, presenting the most appropriate energy policy with a comprehensive analysis. For this purpose, a comprehensive evaluation is conducted by combining DEMATEL and TOPSIS with Quantum Spherical fuzzy sets (QUSEFs) and golden cut: (1) the significance levels of the Quintuple innovation dimensions for planning counterparties are weighted; (2) the relative roles of the innovation counterparties in the Quintuple innovation dimensions are examined; (3) the marketing priorities of innovation counterparties are created; (4) the sustainability of innovative marketing tools is ranked; (5) significant sustainable energy policies are generated. It is concluded that technological issues play a crucial role in generating effective energy policies. The government is also determined to be crucial in generating clean energy policies. Governments have two responsibilities: must create the necessary legal arrangements for these policies, while the financial support governments will provide to investors is about to have a vital role in this process. The findings indicate that using smart systems to increase active participation is the most critical clean energy investment policy. This implementation contributes to increasing energy investment efficiency so that clean energy can become more widespread.
