电力行业碳中和的实现路径与对策

电力行业作为碳排放量大户,其低碳转型是我国实现碳中和目标的关键,但其目前面临煤电"碳锁定"效应、技术设备、可再生能源发展、资金投入等多方面挑战.通过电力行业低碳转型的情景分析,要实现碳中和的目标,必须严格按照1.5℃温升控制目标的路径制定相关政策,采取强力措施保障电力行业在2050年实现零排放或负排放.未来要严控"一煤独大",合理有序做好煤电的退出工作;促进可再生能源技术发展,保障高比例可再生能源发电的实现;优化电网传输规划,加强设施建设;建立具有灵活性的现代化电力市场体系;加强碳捕集、利用和封存技术的研发部署;创新绿色金融工具,保障电力投资规模.

The Attitude of Developed and Developing Countries Towards the Kyoto Protocol and the Case of Turkey

The problem of global climate change is one of the biggest present-day global problems. This problem, which has become a current issue because of the energy crisis that happened in 1970s, as well as growing awareness of environment, have not only changed the notion of development but also led to a transformation of non-renewable energy resources. Due to rapid population growth, the depletion of the non-renewable energy resources and the raising consciousness about global climate change our comprehension of traditional development has yielded to sustainable development, while energy structure and preferences have also changed from non-renewable energy resources to renewable energy resources. As this changed pattern and problem are global, they have removed the borders among governments, required international cooperation and thus, new international actors have stepped in. In this study, the countries are divided into two parts as developed countries and developing countries. As developed countries; USA and EU countries are selected while China and India are selected as developing countries. Also as a developing country, Turkey＇s energy and climate policies, attitude towards the Kyoto Protocol signed within the scope of United Nations and the positive and the negative effects of the Protocol on the country are investigated. In this sense, it has been observed that the question of whether or not the Protocol contributes to the economy of developing countries correlates with whether or not these countries are on the side of the Protocol and it has also been observed that being on the side of the Protocol is not a threat to Turkey＇s development. If applied correctly, the policies that Turkey will pursue within the scope of the Protocol will help the country to reduce foreign energy dependency and cooperate with other countries. A comparative method is used in this paper.     

China＇s Role in Global Climate Change Mitigation

China contributed a majority of the growth in global greenhouse gas emissions in the first 11 years of this century The trajectory of emissions has changed radically since then, as China has irrplemented its Cancun 2010 commitment to reduce the 2005 emissions intensity of economic activity by 40-45percent by 2020. The change in trajectory has been reinforced by China＇s new model of economic growth, with its greater emphasis on equity in income distribution, consumption and services. The large-scale deployment of low emissions technology in China is lowering the cost of transition to a low carbon economy all over the world. China ＇ s new emissions trajectory improves the opportunity For the international community to meet the 2℃ climate target. It is essential that the changes in China are brought to account in shaping global mitigation ambition.     

An Index‐Based Model for Determining the Investment Benchmark of Renewable Energy Projects in South Africa

In a globalised world, financial markets observe the optimal level of asset allocation and returns based on risk inherent in the economies. Whether public or private investors, they need to have an optimal return on their investment given the finite resources. In relatively new sectors like grid‐connected renewable energy, many investors face difficulty in assessing proper return, making them more averse to financing such projects, affecting transborder project development opportunities. In developing countries like South Africa, which has tremendous potential for renewable energy projects, an arbitrary choice of the required rate of return for project evaluations can negatively affect funding decisions. This paper explores an index‐based model to make fair estimates of the required equity benchmark internal rate of return (IRR) using financial markets observation for renewable energy projects in South Africa. The index‐based model is parsimonious and captures common macroeconomic factors. More specifically, it provides a simple and effective mechanism to calculate IRR for renewable energy projects given different gestation periods.     

Analysis of China＇s Renewable Energy Development under the Current Economic and Technical Circumstances

At present, the development of renewable energy relies mainly on government support. The government invests in a considerable number of projects to improve public welfare and to assist in poverty relief If China is to replace fossil fuels on a large scale with renewable energy sources, the production costs and prices of renewable energy must be brought down. All countries are facing the challenge of moving to a more secure and low-carbon energy system without weakening economic and social development. In this regard, China is facing an even greater challenge in terms of economic cost, as cheap coal remains the main energy form. Technical innovation and industrialization in the area of renewable energy is an important means of lowering cost. China is in for a period of high-speed development of its economy and the rising demand for energy is irreversible. If the technical progress and development speed of renewable energy lags behind the growth in demand, it will be difficult to realize the improvement of its energy structure.
