The threat of climate change is a serious global concern. There is near consensus among scientists that the threat is due to man-made emissions of Greenhouse Gases (such as Carbon Dioxide, Methane, Nitrous Oxides, etc).

Sodium intercalation batteries might prove to be a viable alternative of lithium ion batteries, which is both expensive and in short supply due to unavailability of lithium .Renewable energy sources being crucial to India's energy future, there is a huge need to develop scalable and cost effective storage technology with earth abundant materials to provide load balancing. Moving from lithium to sodium ion intercalation materials, electrochemical properties change significantly and electrochemical potential of intercalation drops.

Addressing the challenges of RE manufacturing in India: Horizon 2032

In essence this paper seeks to answer the question: what are the essential elements of
designing as a human activity that makes it possible to transfer these skills and attitudes
beyond the world of design?

The success of the Jawaharlal Nehru National Solar Mission depends on certain critical features – the subsidy structure, the role of standardised systems and institutional models of delivery As the actual costs of small systems are considerably higher, on a per watt basis, than the benchmark costs assumed for the subsidy, smaller systems that are within the reach of the rural poor receive lower subsidies than larger systems.

India's diesel consumption is several times that of petrol In this article, we examine two options for meeting India's diesel demand: coal to liquids and bio-diesel Coal gasification, followed by Fischer-Tropsch (FT) synthesis offers an opportunity for large-scale production of diesel as proven by South Africa, and now being attempted by China and Qatar. India could consider this option given its large coal reserves.

Recently a simple explicit model was introduced to represent the J–V characteristics of an illuminated solar cell with parasitic resistances and bias dependent photocurrent as vm + jn = 1. Here the normalized voltage, v and normalized current density j can be represented as v = V/Voc and j = J/Jsc respectively, where Voc is the open circuit voltage and Jsc is the short circuit current density. This model is useful for design, characterization and simple fill factor calculation and its applicability was demonstrated with the measured data of a wide variety of solar cells.

Due to stochastic nature of wind distribution, wind power output comes with unscheduled changes called ramp events. In this paper, a semi-analytical approach is considered to analyze the distribution of ramp events. A simple empirical equation is derived based on the probability of wind ramp events considering the stochastic nature of wind power distribution for the Indian state of Karnataka.

This paper introduces the concept of using Artificial Neural Network (ANN) techniques for predicting electrochemical potential of cathode materials in combination with first-principles based quantum mechanical calculations. The proposed method can be used to predict the Lithium ion battery voltage if a new material is chosen as cathode. The methodology has low time-space complexity of computation and aims to integrate ANN with quantum mechanics based Density Functional Theory (DFT) calculations for accelerated insertion of new materials into engineering systems.

The power curve of a wind turbine grows exponentially as a function of wind-velocity if the measured wind-velocity varies between the cut-in velocity and the rated velocity In this study, we propose an empirical, two-parameter explicit model of the power curve for a wind turbine.
