Technology portfolio analysis for residential lighting

electricity forces the electricity utilities to increase their generating capacity. The huge investments on generation, transmission and distribution (at the cost of alternative development projects) adversely affect India's scarce capital resources. Also, internal energy resources like coal are utilised with a great risk to the environment. This paper attempts to show analytically the benefits of shift in the focus from supply augmentation to demand management through a case study of replacement of inefficient devices with efficient ones for residential lighting. This is being done by analyzing the economics of various alternatives and developing an optimal portfolio for meeting the lighting requirement of a typical household in Maharashtra State in India. A mixed integer-programming model has been used for developing the optimal portfolio and a comparison of annual returns is made. Finally, the results for the typical household have been extended to the state of Maharashtra and the cost and benefits are estimated. The results show that the optimal lighting portfolio provides a far higher return at a lower risk compared to other investment alternatives like the stock market while providing substantial savings both in terms of energy and peak demand.Demand management, electricity consumption, energy resources, mixed integer-programming model, rate of return

Hydrogen energy for Indian transport sector: A Well-to-wheel techno-economic and environmental feasibility analysis

With the alarming rate of growth in vehicle population and travel demand, the energy consumption has increased significantly contributing to the rise of GHG emissions. Therefore, the development of a viable environmentally benign technology/fuel, which minimises both global and local environmental impacts, is the need of the hour. There are four interconnected reasons for propagating a shift towards alternative fuels/technologies: (i) Energy Supply: world oil reserves are rapidly diminishing, (ii) Environment: local pollution from vehicles is creating an atmosphere that is increasingly damaging public health and environment, (iii) Economic competitiveness: the cost of producing oil and regulating the by-products of oil consumption continues to increase, and (iv) Energy security: the military and political costs of maintaining energy security in international markets are becoming untenable. Hydrogen energy has been demonstrated as a viable alternative automotive fuel in three technological modes: internal combustion engines connected mechanically to conventional vehicles; fuel cells that produce electricity to power electric vehicles; and hybrids that involve combinations of engines or fuel cells with electrical storage systems, such as batteries The present study provides a well-to-wheel analysis of the economic and environmental implications of technologies to deliver the hydrogen energy to the vehicles. The main objectives of the study are: (i) prioritization of technologies of hydrogen production, transportation, storage and refueling, (ii) economic analysis of prioritized technology alternatives to estimate the delivered cost of hydrogen at the end-use point, and (iii) estimating the environmental impacts. To achieve the desired objectives, various quantitative life-cycle-cost analyses have been carried out for numerous pathways (i.e. technologies and processes) for hydrogen production, storage, transportation/distribution and dispensing. The total cost implications are arrived at by combining the costs of hydrogen (at end-use point) and the estimated demand for hydrogen for transport. The environmental benefits (potential to abate GHG emissions) of alternative hydrogen energy technology pathways have been worked out by using the standard emission factors. Finally, the GHG emission levels of hydrogen supply pathways are compared with those of diesel and petrol pathways. The application of this systematic methodology will simulate a realistic decision-making process.

Commercialisation of Sustainable Energy Technologies

Commercialization efforts to diffuse sustainable energy technologies (SETs) need to be sustainable in terms of replication, spread and longevity, and should promote goal of sustainable development. Limited success of diffusion through government driven pathways illustrates the need for market-based approaches to SET commercialization. This paper presents a detailed treatment of the pre-requisites for adopting a private sector driven business model approach for successful diffusion of SETs. This is expected to integrate the processes of market transformation and entrepreneurship development with innovative regulatory, marketing, financing, incentive and intermediary mechanisms. Further, it envisages a public-private partnership driven-mechanism as a framework for diffusion leading to technology commercialization.Commercialisation, Energy, Financing, technology, Sustainable

An Entrepreneurship Model for Energy Empowerment of Indian Households - Economic and Policy Analysis

Provision of modern energy services for cooking (gaseous fuels) and lighting (electricity) is an essential component of any policy aiming to address health, education or welfare issues; yet it gets little attention from policymakers. Secure, adequate, low-cost energy of quality and convenience is core to the delivery of these services. The present study analyses the energy consumption pattern of Indian domestic sector and conceptualizes availability, accessibility, and affordability indicators of modern energy services to households and describes the practical ways of evaluating them. A comprehensive analysis is done to estimate the cost for providing modern energy services to everyone by 2030. A publicprivate partnership-driven business model, with entrepreneurship at the core, is developed with innovative institutional, financing and pricing mechanisms for diffusion of energy services. This approach facilitates largescale dissemination of energy efficient and renewable technologies like smallscale biogas/biofuel plants, and solar water heating systems to provide clean, safe, reliable and sustainable energy to rural households and urban poor. It is expected to integrate the processes of market transformation and entrepreneurship development involving government, NGOs, financial institutions and community groups as stakeholders.Energy Service, Electricity, Biogas, Availability, Accessibility, Affordability

A Comparative Study on Marketing Cost, Marketing Margin and Price Spread for Open versus Protected Cultivation of Tomatoes

The study aims to analyse the marketing cost, marketing margin, price spread, value added in the marketing system and efficiency of different distribution channels in tomatoes marketing which was produced under open and protected environment in Karnataka. The Acharya’s method of marketing efficiency was adopted for the study. The study was conducted during the year 2021 to 2022 in Karnataka. Primary data pertaining to the study were collected from 15 farmers each under open and protected cultivation practices in Kolar and Belagavi districts of Karnataka. The data related to market intermediaries are collected from 15 wholesalers, 15 retailers and 5 private companies from each district with the help of structured schedule. Three marketing channels were identified. These are producer to consumer, producer to wholesaler to retailer to consumer and producer to private companies to consumer. Though the channel comprising producer to consumer was more efficient and producer share in consumer rupee was the highest its share was very less out of the total volume of tomatoes marketed because of limited support from public bodies. The result shows that the channel involving producer to private companies to consumer was most prominent and had higher marketing efficiency and had better producer share in consumer rupee under both open and protected cultivation practices. The Government should take initiative through FPOs for upliftment of direct selling of produce to consumer

Astrophysical molecule CN : vibronic transition probability parameters

Abstract. Astrophysical applications are broadened by the emerging consensus on the vibration-electronic (vibronic) transition probability parameters such as Franck -Condon (FC) factors & r -centroids of some molecular species like CN , which could be useful in the identification of molecular lines and in the estimation of relative abundance of the species in various celestial bodies especially in the interstellar medium. Such important parameters, that is FC factors and r -centroids, have been computed by a reliable numerical integration procedure for the bands of E i systems of astrophysical molecule CN , using a suitable potential. For E − X system, the improved values of FC factors from the revised molecular constants are given along with the already reported values
