Environment, Development and Sustainability, 2023 (SCI-Expanded)
Renewable energy certificates (RECs) are a market-based mechanism used to increase the use of renewable energy sources in electricity generation and consumption worldwide and to disclose the source of electricity supplied by suppliers to end consumers. Interest in these certificates is increasing every day. In this study, national REC mechanisms of Taiwan, Japan and China have been scrutinized and these mechanisms have been compared in terms of design and operation with the Renewable Energy Guarantees of Origin (YEK-G), which is the national renewable energy certification system of Turkey. YEK-G has the potential to contribute to Turkey's sustainable development and renewable energy integration. The YEK-G system's well-structured online certificate trading platform is a key component in encouraging users to trade certificates. Unlicensed power plants must be included in the YEK-G system. YEK-G should be internationally recognized, traded in foreign markets and integrated with international carbon markets. The YEK-G mechanism should not continue on a voluntary basis. It should be supported by regulatory policies such as Renewable Portfolio Standards.
