Abstract

Purpose

In order to accurately predict the uncertain and nonlinear characteristics of China's three clean energy generation, this paper presents a novel time-varying grey Riccati model (TGRM(1,1)) based on interval grey number sequences.

Design/methodology/approach

By combining grey Verhulst model and a special kind of Riccati equation and introducing a time-varying parameter and random disturbance term the authors advance a TGRM(1,1) based on interval grey number sequences. Additionally, interval grey number sequences are converted into middle value sequences and trapezoid area sequences by using geometric characteristics. Then the predicted formula is obtained by using differential equation principle. Finally, the proposed model's predictive effect is evaluated by three numerical examples of China's clean energy generation.

Findings

Based on the interval grey number sequences, the TGRM(1,1) is applied to predict the development trend of China's wind power generation, China's hydropower generation and China's nuclear power generation, respectively, to verify the effectiveness of the novel model. The results show that the proposed model has better simulated and predicted performance than compared models.

Practical implications

Due to the uncertain information and continuous changing of clean energy generation in the past decade, interval grey number sequences are introduced to characterize full information of the annual clean energy generation data. And the novel TGRM(1,1) is applied to predict upper and lower bound values of China's clean energy generation, which is significant to give directions for energy policy improvements and modifications.

Originality/value

The main contribution of this paper is to propose a novel TGRM(1,1) based on interval grey number sequences, which considers the changes of parameters over time by introducing a time-varying parameter and random disturbance term. In addition, the model introduces the Riccati equation into classic Verhulst, which has higher practicability and prediction accuracy.

Abstract

Purpose

The global transition into clean energy demands a re-examination of the link between fossil fuels and clean energy markets. This paper aims to identify the key research areas about clean energy and fossil fuels and outlines emerging themes for future research.

Design/methodology/approach

This paper uses bibliographic mapping to identify the most influential publications among 500 articles published between 1991 and 2022 (as of March 2022). The first step is the identification of literature for inclusion and data cleaning. Next is producing a citation map using Bibliometrix for analysis and synthesis.

Findings

The research on clean energy and fossil fuels has developed into three areas by examining their dynamic causality, return/risk spillovers, and volatility spillovers. However, pr evious studies focus on the oil and clean energy market, and limited studies examine the market linkage. As a result, market linkage presents a challenge in front of energy transition into a green economy.

Originality/value

This paper makes a clear contribution to the literature by identifying the important existing and emerging research areas on the clean energy and fossil fuels market.

Abstract

Purpose

The seventh United Nations' Sustainable Development Goal (SDG 7) is broadly characterised by ensuring affordable and clean energy for all. Considering the need for research associated with SDGs in developing countries, the Brazilian economy importance and its energy matrix, the purpose of this study is to evaluate how Brazil has been acting in favour of 7th SDGs targets.

Design/methodology/approach

The methodological strategy used was a survey conducted with 42 energy planning specialists who know the Brazilian reality. Data were analysed via averages and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) technique.

Findings

The results show that, in general, the actions taken by Brazil to achieve the goals related to SDG 7 have been developed in a simply and punctually form, needing to move considerably towards developing more planned activities; with this, satisfactory and consolidated results are expected on a national scale.

Originality/value

The information presented can significantly contribute to the broadening of debates associated with sustainable development and energy planning, for both academic and political-economic spheres. Information present here can support future more profound studies, and these, in turn, support the Brazilian government in better actions to achieve the SDG 7 targets.

Abstract

Purpose

This paper highlights how biological waste materials can be used for generating the much needed energy and obtaining nutrient-rich compost for agriculture through anaerobic digestion (AD). The paper further highlights the importance of small and medium enterprises (SMEs) in using AD for converting waste to energy (WTE), leading to many environmental benefits as well as clean energy generation. It would help to reduce pollution, water acidification and carbon emissions that eventually lead to climate change.

Design/methodology/approach

The researchers undertook an in-depth study to highlight the role played by an SME in converting WTE and helping towards achieving circularity. An exploratory case-based approach was used to understand value leakage for an AD plant operating on WTE principles in the UK. The plant is still currently active, and it is located in the Midlands, England. Fifteen semi-structured interviews were undertaken with different stakeholders.

Findings

This paper reveals the importance of WTE and the significant role played by AD in converting food waste into useful matter. It reports further into the value leakage issue faced in the AD plants. It demonstrates the importance of technological innovation in SME to capture value leakages in a circular model. Most importantly, it demonstrates how SMEs gain competitive advantage and generate value proposition, while they aim for zero waste to landfill objective.

Research limitations/implications

The research involves a case study based on an SME, operating on a circular business model. It will be worth investigating how other businesses could gain competitive advantage. For SMEs interested in AD for WTE, this paper introduces further technological innovation to the AD process to leverage further potential for reuse of waste liquid. Any SMEs entering WTE market ought to take into consideration such design implications.

Practical implications

The paper reveals how the use of waste by SMEs would lead to many environmental benefits as well as clean energy generation. It would help to reduce pollution, water acidification and carbon emissions that eventually lead to climate change. It is useful for addressing the needs of waste food producers and is a cheap raw material for generating energy. The benefits to the public are that it reduces the need for landfill and increases recycling.

Social implications

The WTE is an effective way of making use of last-stage waste.

Originality/value

Despite SMEs being the powerhouse of the European economies, there is limited research investigating how circular economy (CE) could unlock their potential. Moreover, development of AD in the UK has lagged behind other EU countries. We highlight value leakages and argue how technological innovation should be used to close the value chain loop in the WTE production process. This paper, therefore, demonstrates the important role of an AD process, which involves decomposition of biodegradable materials. It shows that AD is an economically viable and environmentally friendly process of obtaining clean energy at low cost.

Abstract

Purpose

This chapter presents a South American perspective on the environmental and financial sustainability of energy integration incorporating recent financial lessons from the United States and Europe. An illustrative project called UNASUR-GRID is presented to highlight new thinking on funding ecologically sensitive development (post-carbon electricity generation) and regional energy sovereignty via a new regional development bank for the Union of South American Nations (UNASUR) called Bank of the South, Banco del Sur (BDS) 1,2 . Sustainable BDS finance rules are presented that aim to break the link between development funding, environmental damage, and sovereign debt owed to banks outside the region, tapping into alternative finances to buffer the region against changes in global financial flows from core nations in the Great Recession.

Methodology/approach

The author attended presidential meetings of MERCOSUR and UNASUR supplementing this with presidential declarations comparing these with ongoing development planning from IIRSA, also interviewing a COSIPLAN representative. He also cooperated (as an independent researcher) with the Ecuadorian Central Bank research group called ‘New Architectures for Regional Finance’ (NAFR) and conducted technical interviews at South American energy institutes specialising in integration.

Findings

Development finance must reflect changes in both energy supply and demand while replacing fossil fuel inputs in electricity generation. Demand planning is necessary to attain sovereignty over a post-carbon electricity supply while maintaining dependability.

Practical implications

Successful energy cooperation is more than just energy infrastructure (UNASUR-GRID), cross-border confidence building is also required, reinforced by commercial treaties for energy exports and imports. Public and private national and regional energy companies need real incentives to trade internationally (improving competition) or renationalisation of supply and distribution may be necessary.

Originality/value

Highly original, this chapter incorporates government, UN and civil NGO inputs into primary research. BDS policy sources include government, ministerial and presidential speeches with interviews and participation in meetings with social movements. For indigenous ecological and social economic concepts such as Sumak Kawsay, the author has travelled extensively in South America and was an active participant at the first World People’s Conference on Climate Change and the 2010 Rights of Mother Earth (World Conference on Indigenous Peoples, 2014) in Cochabamba, Bolivia, along with ecologists and tribal representatives.
