The Chinese government has made a commitment to control carbon emissions, and the deployment of renewable energy power generation is considered as an effective solution. In recent years, great effort has been exerted to support the development of renewable energy in China. While, due to fiscal pressures and changes in management policies, related subsidies are diminishing now and energy users are asked to pay for the cost. Regulations about carbon cap and renewable energy consumptions are issued to transfer the responsibility of consuming renewable energy and reducing carbon emissions to energy consumers. A national carbon trading system is set up in China and is under its growth stage. Therefore, this study lists the factors that should be considered by the energy users, analyzes the levelized cost of electricity generated by renewable energy in four cities in China, Beijing, Shanghai, Guangzhou, Wuhan, and compares the results with current carbon prices. Based on the research, under the current status, it is still more cost-efficient for enterprises to buy carbon credits than introduce renewable energies, and great differences among cities are shown due to different natural conditions. Besides, with diminishing subsidies and development of the carbon trading market, the carbon price will gradually reflect the actual value and carbon emission reduction costs will become an important part of enterprise expenditure. In the long term, enterprises should link more factors to carbon emissions, like social responsibility and brand image, instead of only the cost.

Renewable energy sources are vital to fulfill the high demands of energy in the present world. The common renewable energy sources are wind, hydropower, nuclear and biomass. However, hydropower is considered the most flexible and consistent renewable energy source because it is comparatively cheaper and more available. Besides hydroelectricity production, hydropower dams can also be useful for irrigation. Though hydropower energy is considered as green energy due to its less carbon emission, still other environmental impacts of hydropower dams are many. Hydropower dams are built based on political ground. Research into the politics of building hydropower dams and environment remains underdeveloped in many ways. Thus, this paper focuses on the issues of politics of building hydropower dams and its impacts on environment. This paper has critically reviewed the extensive literature to examine the argument and counter argument. This paper argues that the building hydropower dams on international river for renewable energy has political as well as environmental impacts. Most of the literature argued that hydropower dams provide renewable energy which produces less carbon emission, but it is argued in this paper that hydropower dams have huge political and environmental impacts nationally and internationally. Displacement of the people and dispute for water distribution among countries due to the building hydropower dams are also considered to be significant for discussion in this paper. Thus, the paper critically examines the impacts and role of hydropower dams on environment, international relations and politics.

With the proposed target of carbon peak and carbon neutralization, the development and utilization of renewable energy with the goal of carbon emission reduction is becoming increasingly important in China. We used the analytic hierarchy process (ANP) and a variety of MCDM methods to quantitatively evaluate renewable energy indicators. This study measured the sequence and differences of the development and utilization of renewable energy in different regions from the point of view of carbon emission reduction, which provides a new analytical perspective for the utilization and distribution of renewable energy in China and a solution based on renewable energy for achieving the goal of carbon emission reduction as soon as possible. The reliability of the evaluation system was further enhanced by confirmation through a variety of methods. The results show that the environment and carbon dimensions are the primary criteria to evaluate the priority of renewable energy under carbon emission reduction. In the overall choice of renewable energy, photovoltaic energy is the best solution. After dividing regions according to carbon emission intensity and resource endowment, areas with serious carbon emissions are suitable for the development of hydropower; areas with sub-serious carbon emissions should give priority to the development of photovoltaic or wind power; high-carbon intensity area I should vigorously develop wind power; high-carbon intensity area II should focus on developing photovoltaic power; second high-carbon intensity areas I and II are suitable for the development of wind power and photovoltaic power; and second high-carbon intensity areas III and IV are the most suitable for hydropower.

AbstractClimate change remains a pivotal area and a persistent challenging issue for deliberation among the nations of the world. Most especially in a country like Nigeria, where fossil fuel remains a pivotal source of socio-economic development and well-being of the society. Transforming the Nigeria electricity sector into a source for reducing the country’s carbon emission remains a significant challenge to policymakers, i.e. the Government. This is attributed to the fact that the nation’s primary energy sources come from traditional biomass and fossil fuel such as coal, and natural oil and gas, which has contributed significantly to the level of carbon emissions. In this paper, we explored and identified the potentials, barriers and option for renewable energy in Nigeria. The findings of the review revealed that the Nigerian electricity sector is crucial to reducing the carbon emission generated in the country. Likewise, it is of no doubt that Nigeria is endowed with a different mix of renewable energy sources. Hence, exploring and developing these renewable energy sources will aid the effort of the government in reducing the country’s input to the global carbon emission, instrumental to the socio-economic development of the country and improved well-being of the society at large. Also, policy recommendations to foster renewable energy development were identified.

The rise of environmental protection and the progressive exhaustion of traditional fossil energy sources have increased the interest in integrating renewable energy sources into existing power systems. The energy saving and emission reduction is of most importance. Wind energy could be one of the most promising renewable energy sources. However, the intermittency and unpredictability of wind power generation creates difficulty in control of frequency and generation scheduling. Many problems will arise in the renewable energy based hybrid power system. In this paper, a fuzzy unit commitment model including wind generators is presented. Primary energy consumption, gas emission and the risk of wind are synthetically considered. Through defining membership function, the deterministic problem is transformed into the fuzzy problem. Then it is reformulated into the nonlinear problem by means of the maximum-minimum fuzzy satisfaction. Improved Genetic Algorithms (IGA) is used to solve the fuzzy optimization problem. The simulation results of a 10-unit system demonstrate that the proposed method is feasible. It can compromise between the primary energy consumption and the risk according to the decision-maker’s will. It provides valuable information in both operational and planning problems in the future.
