Achieving net-zero carbon emissions by 2050 has become a global consensus, and countries around the world are gradually conducting energy transitions to reach this goal. This study uses Germany and France as examples, employing a comparative analysis to explore how differences in their energy transition policies impact electricity prices, net electricity exports, and carbon emissions, with the aim of providing insights for Taiwan′s energy transition policies. The results show that in terms of electricity prices, Germany′s imposition of a renewable energy surcharge to fund renewable energy infrastructure has led to higher increases in both residential and industrial electricity prices compared to France. Regarding net electricity exports, France′s net electricity exports have remained relatively stable, while Germany′s have been declining since 2017, turning the country into a net importer by 2023. This shift is primarily due to Germany′s anti-nuclear policy and the economic advantages of importing electricity from abroad. In terms of carbon emissions, due to differences in nuclear policies and the share of thermal power generation, Germany′s carbon emission factor for electricity is about six times higher than that of France. The current state of energy transition shows that both Germany and France have well-established goal systems, monitoring mechanisms, and advanced model assessment methods that have effectively advanced their energy transitions. In contrast, Taiwan still lacks comprehensive monitoring platforms and quantitative assessment tools. Although Germany′s progress in renewable energy is on track with its targets, if factors related to electricity generation and consumption are excluded, the progress would fall short by approximately 20%. This study suggests that Taiwan should refer to the experiences of Germany and France to establish a robust energy transition model, regularly reviewing progress and making necessary adjustments. Based on Germany′s experience, the phase-out of nuclear power has led to increased electricity prices and reduced power generation. Given Taiwan′s isolated grid system, it is recommended to carefully evaluate the economic impacts of adopting a similar model. Additionally, France′s carbon emission factor for electricity is significantly lower than Germany′s. In summary, it is suggested that Taiwan′s energy policy may be better suited to following the French model, maintaining a nuclear power foundation while developing renewable energy to balance environmental goals, economic development, and energy security. |
