Abstract
Purpose
Renewable energy sources are likely to play a major role in meeting the future energy requirement of a developing country like India. Among the various renewable energy sources, the bio‐energy plays a key role for the power generation. In this paper, an attempt is made to develop a fuzzy based linear programming optimal electricity allocation model (OEAM) that minimizes the cost and determines the optimum allocation of different energy sources for the centralized and decentralized power generation in India with special emphasis to bio‐energy.
Design/methodology/approach
The OEAM model optimizes and selects the appropriate energy options for the power generation on the factors such as cost, potential, demand, efficiency, emission and carbon tax. The objective function of the model is minimizing the cost of power generation. The other factors are used as constraints in the model. The fuzzy linear programming optimization approach is used in the model.
Findings
The extents of energy sources distribution for the power generation in the year 2020 would be 15,800 GWh (4 per cent) from the coal based plants, 85,400 GWh (20 per cent) from the nuclear plants, 191,100 GWh (44 per cent) from the hydro plants, 22,400 GWh (5 per cent) from the wind mills, 45,520 GWh (11 per cent) from the biomass gasifier plants, 14,112 GWh (3 per cent) from the biogas plants, 8,400 GWh (2 per cent) from the solid waste, 33,600 GWh (8 per cent) from the cogeneration plants and 11,970 GWh (3 per cent) from the mini hydel plants, respectively.
Originality/value
The OEAM has been developed for the electricity demand allocation for the year 2020. An extensive literature survey revealed that carbon tax and emission constraints were never used in the previous models and they are considered in the present model.

Abstract
Purpose
The impact of climate change (CC) has become the most defining issue of the present times. From an increase in temperature to food and water scarcity, the adverse effect of CC is faced globally by all countries on an unprecedented level. Environmentally polluting industries are considered one of the primary contributors to the problem of CC. This chapter aims to provide an understanding of the emerging global threat of CC and various strategies that environmentally polluting firms could undertake to tackle the climate change crisis.
Methodology
Based on the review of the literature, this chapter presents deliberation on the climate change crisis and various strategies for environmentally polluting industries to tackle CC issues.
Findings
This chapter presents a bird's eye view of the CC issue and various strategies that could be undertaken by environmentally polluting industries to address the CC crisis.
Implications
This chapter should be very useful for policymakers, practitioners and corporations to understand the issue of climate change and global warming and its implications. Further, it will also help polluting companies to reduce greenhouse gas (GHG) emissions and address the adverse impact of their business activities.
Originality
Considering the dearth of sector-specific studies based on climate change, this chapter is one of the few studies that explore CC strategies in the context of polluting industries.

Abstract
Purpose
The clean development mechanism (CDM) provides industrialized countries with an incentive to invest in emission reduction projects in developing countries to achieve a reduction in CO2 emissions at lowest cost that also promotes sustainable development in the host country. Windmill pumps could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development. This study aims to assess the maximum theoretical as well as the realistically achievable CDM potential of windmill pumps in India.
Design/methodology/approach
To estimate the CDM potential of windmill pumps in case of electricity replacement (by the substitution of electric motor pumps) regional baseline(s) has been used whereas in case of diesel replacement (by the substitution of diesel engine pumps) the IPCC emission factor(s) has been used. The authors have analyzed the financial feasibility of five designs of windmill pumps at ten select locations in India to justify the financial additionality of windmill pump‐based CDM projects. To analyze the future dissemination levels of windmill pumps logistic growth model has been used.
Findings
The annual CO2 emissions mitigation potential through windmill pumps in India could theoretically reach five million tones. Under more realistic assumptions about diffusion of windmill pumps based on past experiences with the government‐run programmes, annual CER volumes by 2012 could reach 13,000‐46,000 and 0.07‐0.3 million by 2020. This would require that the government sets the subsidy level for windmill pumps at a level that allows them to become viable with the CER revenue. From a macro‐economic point of view, this makes sense if the sustainability benefits are deemed sufficiently high to warrant promotion of this project type.
Originality/value
The paper illustrates the vast theoretical potential of CO2 mitigation by using windmill pumps for irrigation water pumping in India.

This paper aims to present a forecast for renewable energy production in the USA. Growth curves are used to conduct the forecasts.
Abstract
Purpose
This paper aims to present a forecast for renewable energy production in the USA. Growth curves are used to conduct the forecasts.
Design/methodology/approach
The analysis is based upon a literature review, supplemented by collection of secondary data. The study then focuses on applying the Pearl growth curve.
Findings
The authors' results show that biomass energy production is growing the fastest followed by geothermal and wind. Additionally, the forecast for solar energy production shows little to no growth over the next two decades.
Research limitations/implications
If the US government hopes to achieve its goals in renewable energy, considerable funding and incentives will have to be put forth to accelerate the growth of renewable energy. Since the biomass technology is already growing nicely it makes sense to put the additional resources behind the other three technologies to close the 10.3 percent gap being forecasted. The government also needs to put more funding into dual renewable plants such as wind or solar combines with pumped hydro, this will ensure environmental and reliability are both maintained. Finally, for renewable energies to be competitive in the long term, considerable research needs to go into driving down the cost so there is not a need for subsidies.
Originality/value
This study provides value in providing a forecast for expected future growth for renewable energy sources.

Abstract
Purpose
The purpose of this paper is to address the question of how a developing country, like Mexico, can reform its electricity industry at the same time as addressing climate change issues.
Design/methodology/approach
The objective is to provide a tool that policy makers could use to make better and more informed decisions if they decide to liberalise the power sector in Mexico. The problems they would face are difficult to address in an analytically tractable way using conventional economic models. Also, these problems are too idiosyncratic to solve by translating empirical experience from other markets. In response, a system dynamics model has been developed in order to test the impact of a range of different environmental and energy policies.
Findings
The paper finds that a reform setting where competition is allowed in fossil fuel technologies; while the public company (CFE) keeps control of hydro and nuclear capacity produce the most well rounded scores in terms of efficiency, CO2 emission reductions and political feasibility. The results could improve the policy implementation process by shedding light on the circumstances and policy choices that can exacerbate or minimise effects.
Research limitations/implications
A simulation of this kind would increase the understanding of these kinds of policies by providing structured insights into key uncertainties. They can also foster new ideas – in the energy sector have underpinned major policy initiatives. But results should be taken with caution, as complete validation of models is impossible.
Practical implications
These results add to the policy implementation literature. For the case of Mexico that has not engaged in a specific model of deregulation, the use of simulation model would be very useful to predict flaws in the design of the new regulation and to prevent unwanted scenarios to happen.
Social implications
A judicious implementation of an electricity reform can help achieve lower carbon emissions reductions which would be beneficial against the climate change problem.
Originality/value
To the author's knowledge, the approach of analysing ex ante the environmental outcome of electricity reform using a simulation model in a developing country has not been treated in literature.

This paper aims to use artificial neural networks to develop models for forecasting energy demand for Australia, China, France, India and the USA.
Abstract
Purpose
This paper aims to use artificial neural networks to develop models for forecasting energy demand for Australia, China, France, India and the USA.
Design/methodology/approach
The study used quarterly data that span over the period of 1980Q1-2015Q4 to develop and validate the models. Eight input parameters were used for modeling the demand for energy. Hyperparameter optimization was performed to determine the ideal parameters for configuring each country’s model. To ensure stable forecasts, a repeated evaluation approach was used. After several iterations, the optimal models for each country were selected based on predefined criteria. A multi-layer perceptron with a back-propagation algorithm was used for building each model.
Findings
The results suggest that the validated models have developed high generalizing capabilities with insignificant forecasting deviations. The model for Australia, China, France, India and the USA attained high coefficients of determination of 0.981, 0.9837, 0.9425, 0.9137 and 0.9756, respectively. The results from the partial rank correlation coefficient further reveal that economic growth has the highest sensitivity weight on energy demand in Australia, France and the USA while industrialization has the highest sensitivity weight on energy demand in China. Trade openness has the highest sensitivity weight on energy demand in India.
Originality/value
This study incorporates other variables such as financial development, foreign direct investment, trade openness, industrialization and urbanization, which are found to have an important effect on energy demand in the model to prevent underestimation of the actual energy demand. Sensitivity analysis is conducted to determine the most influential variables. The study further deploys the models for hands-on predictions of energy demand.

Abstract
Purpose
Sustainability is an accepted measure of business performance, with reductions in energy demand a commonly practised sustainability initiative by multinational corporations (MNCs). Traditional energy models have limited scope when applied to the entire MNC as the models exhibit high data and time intensity, high technical proficiency, specificity of application and omission of non-manufacturing activities. The purpose of this paper is to propose a process centric energy model (PCEM), which adopts a novel approach of applying business processes for business energy assessment and optimisation. Business processes are a fundamental requirement of MNCs across all sectors. The defining features of the proposed model are genericity, reproducibility, minimum user input data, reduced modelling time and energy evaluation of non-manufacturing activities. The approach forwards the adoption of Industry 4.0, a subset of which focuses on business process automation or part thereof.
Design/methodology/approach
A quantitative approach is applied in development of the PCEM. The methodology is demonstrated by application to the procure to pay and electroplating business processes.
Findings
The PCEM quantifies and optimises the business energy demand and associated carbon dioxide emissions of the procure to pay and electroplating business processes, validating the application of business processes. The application demonstrates minimum user inputs as only equipment operational parameters are required and minimum modelling time as business process models and optimisation options are pre-defined requiring only user modification. As MNCs have common business processes across multiple sites, once a business process energy demand is quantified, its inputs are applied as the default in the proceeding sites, only requiring updating. The model has no specialist skills requirement enabling business wide use and eliminating costs associated with training and expert’s services. The business processes applied in the evaluation are developed by the researchers and are not as comprehensive as those in actual MNCs, but is sufficiently detailed to accurately calculate an MNC energy demand. The model databases are not exhaustive of all resources found in MNCs.
Originality/value
This paper provides a new approach to MNC business energy assessment and optimisation. The model can be applied to MNEs across all sectors. The model allows the integration of manufacturing and non-manufacturing activities, as it occurs in practice, providing holistic business energy assessment and optimisation. The model analyses the impacts of the adoption of Industry 4.0 technologies on business energy demand, CO2 emission and personnel hours.

Abstract
Carbon emission is one of the most important problems of today. In this framework, it is important for countries to take the necessary actions to solve this problem. Energy use is one of the most important causes of carbon emissions. Choosing fossil fuels in this process increases the carbon emission problem. Therefore, it is understood that countries should be more sensitive about energy types. In this context, renewable energy (RE) sources are recommended by experts. However, due to some problems of these energy types, it does not seem possible to meet all energy needs from these sources. It is thought that nuclear energy will produce a permanent solution to the carbon emission problem. In this context, it is recommended that the use of nuclear energy be put on the agenda by countries.

Abstract
Purpose
The purpose of this paper is to explore whether the private sector consider voluntary involvement in efforts to combat the impacts of climate change in the lines mitigation approaches and adaptation approaches. Today’s world has increasingly become aware of the adverse effects of climate change and its impact on the poor, though the latter impact is not that well known. To address these impacts, recommendations exist that follow two different though interrelated approaches – mitigation and adaptation.
Design/methodology/approach
Using a survey questionnaire as the research instrument and a sampling frame of 350 junior corporate executives, an empirical study was conducted in the Chennai area in southern part of India to evaluate/measure the linkages between awareness to climate change, its impact on the poor and the willingness of private sector to act on adaptation as well as mitigation strategies.
Findings
From the data analysis, it emerges that there is significant awareness about the impacts of climate change, though the awareness to vulnerability of the poor is not yet significant in Chennai area in the private sector. However, the study concludes that there does exist a significant linkage between awareness and the willingness to support adaptation strategies on the part of junior corporate executives.
Research limitations/implications
The study is country specific because the research was carried out in a defined region in India.
Practical implications
Because the study brought out the result that private sector was willing to participate in adaptation strategies, extensive awareness building can be carried out for corporate executives and plan out activities which will enable them to participate in adaptation strategies which would help the poor in India to help address the devastations caused by Climate Change from time to time.
Social implications
Executives taking up the Climate Change adaptation strategy would help protect and benefit all communities especially the poor in the country. Companies operating in India would find an avenue to reach out in their efforts to touch communities around them. Employees in such companies may be organized and gathered together to participate in such reach-out activities on the part of the companies.
Originality/value
This paper fulfils urgent need to inspire the corporate executives to take up initiatives related to climate change. The paper lays the groundwork on which an array of corporate activities can be developed to implement the adaptation strategies. Further extensive thinking can follow this research as to where and how exactly private sector can help.

Abstract
Purpose
This study aims to investigate the unsteady magnetohydrodynamic mixed convective nanofluid flow by using Buongiorno two-phase model to achieve an appropriate mechanism to improve the efficiency of solar energy systems by mitigating the energy losses.
Design/methodology/approach
The transport phenomena occurring in this physical problem are modelled using nonlinear partial differential equations and are non-dimensionalised by using non-similar transformations. The quasilinearisation technique is used to solve the resulting system with the help of a finite difference scheme.
Findings
The study reveals that the effect of the applied transverse magnetic parameter is to increase the temperature profile and to reduce the wall heat transfer rate. The Brownian diffusion and thermophoresis parameters that characterise the nanofluids contribute to the reduction in wall heat transfer rate. The presence of nanoparticles in the fluid gives rise to critical values for the thermophoresis parameter describing the behaviour of the wall heat and mass transfer rates. Wall heating and cooling are analysed by considering the percentage increase or percentage decrease in the heat and mass transfer rates in the presence of nanoparticles in the fluid.
Research limitations/implications
The investigation on wall cooling/heating leads to the analysis of control parameters applicable to the industrial design of thermal systems for energy storage, energy harvesting and cooling applications.
Practical implications
The analysis of the control parameters is of practical value to the solar industry.
Social implications
In countries, such as South Africa, daily power cuts are a reality. Any research into improving the quality of energy obtained from alternate sources is a national necessity.
Originality/value
From the literature survey in the present study, it is found that no similar work has been reported in the open literature that analyses the time-dependent mixed convection flow along the exponentially stretching surface in the presence of the effects of a magnetic field, nanoparticles and non-similar solutions.
