PurposeThe Indian power sector is dominated by coal. Environmental awareness and advances in techno-economic front have led to a slow but steady shift towards greener alternatives. The distributions of both fossil fuel resources and renewable energy potential are not uniform across the states. Paper attempts to answer how the states are performing in the sector and how the renewable energy and conventional resources are affecting the dynamics.Design/methodology/approachThe authors employ a two-stage data envelopment analysis (DEA) to rank the performance of Indian states in the power sector. Multi-stage analysis opens up the DEA black-box through disaggregating power sector in two logical sub-sectors. The performance is evaluated from the point-of-view of policy formulating and implementing agencies. Further, an econometric analysis using seemingly unrelated regression equations (SURE) is conducted to estimate the determinants of total and industrial per-capita electricity consumption.FindingsEfficiency scores obtained from the first phase of analysis happens to be a significant explanatory variable for power consumption. The growth in electricity consumption, which is necessary for economic wellbeing, is positively affected by both renewable and non-renewable sources; but conventional sources have a larger impact on per-capita consumption. Yet, the share of renewables in the energy mix has positive elasticity. Hence, the findings are encouraging, because development in storage technologies, falling costs and policy interventions are poised to give further impetus to renewable sources.Originality/valueThe study is one of the very few where entire spectrum of the Indian power sector is evaluated from efficiency perspective. Further, the second phase analysis gives additional relevant insights on the sector.

The status of engineering education in the country is briefly reviewed. A problem faced by the industry in regard to the quality of the engineering graduates of whom 70 to 80% are considered “unemployable,” is examined. The mismatch between the skillset required by the industry and that provided by the academic institutions is identified as the major reason for the low employability of engineering graduates. Various ongoing efforts at the level of the government and academia to rectify this situation are described. Measures that could be usefully adopted by the corporate sector are identified. Intensive combined action by all the stakeholders involved in the academic process will only enable the country to reverse the trend of declining academic standards in higher technical education. The case of the Power Sector has been discussed at length to illustrate the points made. During the 11th and 12th plan periods, five lakh technical personnel and 1.5 lakh front end support personnel need to be recruited by the Power Sector as per published reports. There is also a huge requirement of back end staff to take up various managerial functions. Use of alternate sources of energy and efficient management of energy being inevitable, a huge pool of human resources would be required in harnessing small hydro, biomass & bio-fuel, solar, and wind resources, provided they have the appropriate specialized knowledge. Moreover, demand side management, power trading, carbon credits, smart grids, etc. will also require manpower with specialized training. Salient features of the human capital challenges in the Indian power sector are discussed, and certain action plans to overcome the challenges are suggested.
