Special Issue Information

Dear Colleagues,

Carbon neutrality refers to achieving net zero carbon dioxide emissions by balancing carbon dioxide emissions with carbon sequestration or by eliminating emissions. In response to global climate urgency and the Glasgow Climate Pact with a target of 1.5 °C temperature increase by the end of this century, about 65% of the world’s emissions are now subject to some form of carbon-neutrality or net-zero-emissions goal, for which renewable energy and clean technology will play a critical role. More than forty countries, including China, the United States, the United Kingdom, and the EU, have pledged to work together for the delivery of clean technology through encouraging global investment in renewable energy and low-carbon technologies.

Given the critical significance of understanding renewable energy supply and consumption for the accelerated achievement of carbon neutrality, this Special Issue focuses on renewable energy from the perspective of both supply and consumption sides, particularly in the context of carbon neutrality. Specifically, this Special Issue invites theoretical and empirical studies on the following themes, although other relevant topics will also be considered:

  • Interactions and processes among renewable energy supply, consumption and carbon neutrality;
  • Discussion on the possibility of renewable energy supply and consumption;
  • Transformation of energy mix;
  • Potential impacts on renewable energy supply and consumption;
  • Low-carbon technologies;
  • Renewable energy transition and its barriers;
  • Renewable energy policy;
  • Renewable-energy-based climate solutions and their potential outcomes/impacts.

Developing new energy is one of the most important measures to implement global carbon neutrality. Under the constraints of carbon emission reduction, the question of how to achieve the sustainable development of new energy enterprises has become an important issue among managers and investors. This study selects Chinese listed companies in the new energy industry as the research sample, employs the DID method and uses panel data to explore the role of carbon neutrality commitment in the sustainable growth of new energy companies. The results show that the carbon neutrality commitment has greatly improved the sustainable development of Chinese new energy companies, with the internal profitability and external investor sentiment of the enterprises being important mediating variables. Moreover, the effect of the carbon neutrality commitment on the sustainable growth of non-state-owned new energy firms is much more significant compared with that of state-owned enterprises, and the effect is more robust in the east than in the central and western regions. Based on the conclusions, this study provides practical implications for managers, investors and policymakers in order to promote the sustainable growth of new energy firms. Full article

In this paper, we provide theoretical and policy support for quota-allocation strategies based on a national unified renewable energy (RE) power market. Renewable portfolio standards (RPSs) are of great significance in promoting the stable development of renewable energy and improving power market decision making in China’s power industry. To resolve the geographical, resource allocation, and power-grid problems of multi-regional RE power generation, we constructed a regional distribution optimization model with the lowest cost under the RPS policy and designed a set of dynamic distribution mechanisms based on the renewable energy power quota index. The results show that it is necessary to prioritize development of wind-generated power on the North China and Northeast Power Grids, solar energy on the Northwest Power Grid, and biomass energy generation on grids in other regions to plan specific task undertakings and allocate RE power generation to each grid. We propose a multi-regional power distribution model at the lowest cost under the RPS policy to provide solutions and references for renewable energy power market quota allocation. Full article

The inter-cycle sleep design previously proposed as a power-saving scheme for next-generation Ethernet passive optical networks (NG-EPONs) is able to effectively decrease the power consumption of heavy-load traffic. However, with a medium to high traffic load, these networks may still suffer from a high level of power consumption if no enhanced mechanisms are used. It was noted that the optical line terminal (OLT) often fully opens all communication channels at a medium to heavy load. Moreover, the number of opened channels was changed cyclically according to the traffic loading status. Accordingly, optical network units (ONUs) may be frequently allocated to different channels with changing loads. This may lead to inefficient operation and result in significant channel tuning delays. We thus propose a loading-aware time-division multiple access (TDMA) mechanism that allows the OLT to reserve a maximum bandwidth for each ONU when the network experiences heavy-load traffic. The performance results of our simulations reveal that the proposed scheme is able to reduce power consumption for targeted medium to high loads since ONUs under such loads can extend their sleep time because the cycle length is maximized. Moreover, the total delay is maintained at a relatively low level after applying the proposed scheme since the tuning delay is reduced significantly; however, the transmission delay is slightly increased due to the increased cycle length.
