The purpose of this paper is to design a contract to coordinate the biomass molding fuel supply chain consisting of a supplier with uncertain supply and a producer with cyclical demand as well as improve the profit of this supply chain.

In this paper, the supply chain model was build and all the variables and assumptions are set. Stackelberg game model was used to analyze and solve the problem. Furthermore, the authors give numerical examples and result analysis on the basis of data coming from field study and online information about a real biomass fuel supply chain.

The wholesale price with shortage penalty contract the authors proposed can coordinate the supply chain. And as the dominator of the supply chain, the producer can realize the redistribution of profits within the supply chain by determine the contract parameters.

This one-to-one supply chain is a basic of complex supply chain system. Multi-to-one, one-to-multi and multi-to-multi supply chain can be studied in the future.

The results obtained in this paper can be used as a reference for enterprises in biomass energy supply chain to make contracts and realize the long-term co-operations among supply chain members.

The increasing accumulation of synthetic plastic waste in oceans and landfills, along with the depletion of non-renewable fossil-based resources, has sparked environmental concerns and prompted the search for environmentally friendly alternatives. Biodegradable plastics derived from lignocellulosic materials are emerging as substitutes for synthetic plastics, offering significant potential to reduce landfill stress and minimise environmental impacts. This study highlights a sustainable and cost-effective solution by utilising agricultural residues and invasive plant materials as carbon substrates for the production of biopolymers, particularly polyhydroxybutyrate (PHB), through microbiological processes. Locally sourced residual materials were preferred to reduce transportation costs and ensure accessibility. The selection of suitable residue streams was based on various criteria, including strength properties, cellulose content, low ash and lignin content, affordability, non-toxicity, biocompatibility, shelf-life, mechanical and physical properties, short maturation period, antibacterial properties and compatibility with global food security. Life cycle assessments confirm that PHB dramatically lowers CO₂ emissions compared to traditional plastics, while the growing use of lignocellulosic biomass in biopolymeric applications offers renewable and readily available resources. Governments worldwide are increasingly inclined to develop comprehensive bioeconomy policies and specialised bioplastics initiatives, driven by customer acceptability and the rising demand for environmentally friendly solutions. The implications of climate change, price volatility in fossil materials, and the imperative to reduce dependence on fossil resources further contribute to the desirability of biopolymers. The study involves fermentation, turbidity measurements, extraction and purification of PHB, and the manufacturing and testing of composite biopolymers using various physical, mechanical and chemical tests.

Different pollutants emission due to the conventional energy consumption process is of major concern owed to its significant effect on human health vis-à-vis regional climate. The purpose of this paper is to develop mitigation strategies to reduce the pollutant concentrations in the rural households conducted in a pristine rural village of Indian Sunderban area.

During winter, 2014, 20 households which were using traditional biomass cookstove for cooking and kerosene-lamp for lighting (KIT-TRD) were randomly selected. Specific type of improved forced draft biomass cookstove and solar lantern were used in ten of the selected households (KIT-IMP). Real time concentrations of particulate matter (PM) (PM_2.5, PM₁₀) and carbon monoxide (CO) during day and evening time cooking period were measured in KIT-IMP and KIT-TRD. A simulation model was established to evaluate most potential factor to control the level of pollutants inside the kitchen.

Conventional processes of energy consumption in the households, along with the outdoor concentration of pollutants influence the indoor concentration of measured pollutants. The concentration of PM and CO was significantly lower in the KIT-IMP than the other. In the KIT-TRD households, the daytime concentration of PM and CO was significantly higher compared to the evening. The simulated output overestimated the concentration of PM10 and CO in the KIT-TRD.

The concentration of PM_2.5, PM₁₀ and CO significantly reduces in the indoor environment with the introduction of improved cookstove and solar lantern; however, further research is required to develop optimum sizes of window and door in the rural households to reduce the concentrations of different pollutants inside the kitchen.

The purpose of this chapter is twofold. First, to show how the financial power of the fossil fuel industries and the prevalence of religious ideology in Congress are the two major obstacles preventing the U.S. government from taking action to slow down global warming. Then to evaluate various approaches to ‘satisfying our energy needs’, by showing a crucial dynamic behind our insatiable drive to consume energy, and to propose some ways of circumventing the current obstacles.

The approach is through a comprehensive study of the relevant evidence and academic literature, interwoven with philosophical reflections on their significance.

The findings are as follows: a major root of the current problem is the dysfunctional political system in the United States, which is corrupted by vast infusions of money from the fossil fuel industries and the dogmatic religious beliefs of Republicans in key positions on Congressional committees.

The implications are several. The proposed technological solutions to the ‘energy problem’ – nuclear power, carbon sequestration, fracking for natural gas and geo-engineering – only address the symptoms and ignore the dynamic that underlies them, exemplified in the story of Prometheus. If we continue to be driven by the Promethean spirit, we risk being subject to excruciating punishment as a result. The solution to our problems is a transition to clean and renewable sources of energy, accompanied by the kind of reduction in material desires that evidently makes for lives that are more fulfilled.

The value of the philosophical perspective on this topic is that it highlights questions of value that otherwise remain inexplicit.

Coal, a fuel that once dominated the global energy scene, is staging a come‐back despite being environmentally dirty. The purpose of the paper is to analyse the return of King Coal to find out whether it is likely to be regain its dominance in the global energy in the future.

In analysing the metamorphosis of the coal industry, the paper looks at the historical evolution of the industry and analyses the factors behind the change. The deficiencies of coal's competitors are also analysed. Using a scenario analysis, the future role of coal in the global energy mix is estimated as well.

The paper finds that despite the domination of hydrocarbons in the global energy mix, coal has maintained a steady share and in some countries, it remained the main fuel. With the concerns of high‐oil prices and peak oil, coal is regaining its domination in the power sector around the world. The industry has reformed and restructured itself to remain competitive. Consequently, it has the possibility of staging a come back as a dominant fuel.

The paper is the first of its kind to take a long‐term perspective of the coal industry to analyse its re‐emergence as a dominant fuel. It combines the industry‐wide information to analyse the changes that swept the industry. It contributes by improving the academic understanding of a neglected fuel that still plays an important role.

This paper seeks to outline the technical characteristics of certain biodegradable lubricants which can lead to potential energy savings.

Reviews the reasons for introduction of biodegradable lubricants, and describes the outcome of development and establishment of suitable range of lubricants for almost all applications.

Plant‐based lubricants have low toxicity, they are derived from crop resources, they are recognised as safer to use, and are rapidly biodegradable when spilled on to open land or into water. As such they break down to reduce pollution burden and are favoured by the Environment Agency when used near watercourses. Products have been developed now for almost all applications including hydraulics, engines, transmissions, compressors, metalworking, turbines, and for use in all industry sectors. Latest generation biolubricants, however, give additional advantages above and beyond the original concept to reduce pollution: the latest products have high levels of performance in terms of both loading and temperature. In particular, their frictional characteristics have been shown to be considerably more favourable than those for mineral oil, offering energy reduction during use.

The paper is restricted to findings based on ester‐based synthetic lubricants where the esters have been derived principally from renewable resources.

Quite apart from their environmental attributes, reduced energy consumption and therefore lower variable costs are now possible, and the concept of use of these oils to give distinct savings is becoming recognised.

This study emphasises that distinct advantages for synthetic lubricants, particularly for biodegradable synthetic ester lubricants derived from renewable resources, are now being realised.

Leadership

In 2019, French multinational electric utility company, ENGIE SA (ENGIE) was on the verge of zero carbon transition. Under the leadership of Isabelle Kocher (Kocher) who became the CEO in 2016, ENGIE embarked on an arduous journey toward re-profiling ENGIE toward renewable, low-carbon energies, such as solar, green gases and digital. Kocher inherited a loss-making company and took in on a path of transformation toward a company with business lines for future. This meant ENGIE would slowly move out of energy generation through non-renewable sources, toward renewables along with storage and digital technologies. This case chronicles Kocher’s turnaround plans and investments, and explains how she went about making ENGIE a forerunner in energy revolution. While the turnaround was on track, ENGIE was unable to give returns as expected. With mounting pressure Kocher announced a strategic plan in 2019, which reemphasized ENGIE’s focus on renewables and technology. But several major shareholders including the Government of France were not impressed with the plan. It is time Kocher proves that transformation of ENGIE into a clean power company also means returns for the shareholders.

The purpose of this study is to investigate the impacts of urbanization on per capita energy consumption and emissions in India.

The present study analyses the effects of urbanization on energy consumption patterns by using the Stochastic Impacts by Regression on Population, Affluence and Technology in India. Time series data from the period of 1960 to 2015 has been considered for the analysis. Variables including Population, GDP per capita, Energy intensity, share of industry in GDP, share of Services in GDP, total energy use and urbanization from World Bank data sources have been used for investigating the relationship between urbanization, affluence and energy use.

Energy demand is positively related to affluence (economic growth). Further the results of the analysis also suggest that, as urbanization, GDP and population are bound to increase in the future, consequently resulting in increased carbon dioxide emissions caused by increased energy demand and consumption. Thus, reducing the energy intensity is key to energy security and lower carbon dioxide emissions for India.

The study will have important policy implications for India’s energy sector transition toward non- conventional, clean energy sources in the wake of growing share of its population residing in urban spaces.

There are limited number of studies considering the impacts of population density on per capita energy use. So this study also contributes methodologically by establishing per capita energy use as a function of population density and technology (i.e. growth rates of industrial and service sector).
