The data set covers 150 inventory news released by the Energy Information Administration (EIA) for each commodity. Across a range of specifications, we find strong evidence for the negative effect of inventory surprises on energy commodity futures returns on the day of the announcement. In contrast, the effect after the announcement day becomes insignificant. Moreover, in separating inventory announcements into positive and negative surprises, we find that asymmetric responses in returns to EIA inventory shocks are pronounced for energy commodity. Finally, we show that natural gas volatility is susceptible to both positive and negative inventory surprises, whereas surprises do not matter for crude oil volatility. Journal: Int.

We develop the analysis with four copula-based TGARCH models. The main findings show that: (1) the Clayton-TGARCH distribution seems to characterise the co-movements between the series; (2) leverage effects of the exchange rate returns are bigger than the ones of the oil returns; (3) the series show lower tail dependence; and (4) extreme downfalls in oil returns may reduce exchange-rate ones with a probability of less than 10%. The study relies on series of weekly returns for the period between 2 January 1998 and 30 September 2016. Journal: Int.

We first present the emerging new actors in the evolving smart grid value chain. We then focus on the role of MNOs and study the different roles they could play in this value chain, not only as connectivity providers for connecting consumers to distributed energy storage and production facilities and for ensuring demand-response, but also with regards to their expertise as Internet of Things (IoT) players and their energy generation and storage assets. Based on this ecosystem analysis, we build three business models canvasses for the MNO as a Demand Response (DR) aggregator, as a Virtual Power Plant (VPP) and as an enhanced VPP where it also acts as a prosumer with generation/storage facilities. We show that the first two services fit very well with the European context, while the third is well suited for sub-Saharan African countries. Journal: Int.

Since the cost of energy is very high so these are the best test place for the implementation of the new technologies. We have considered the case of Lakshadweep Island which is one of a union territory of India. In Lakshadweep electricity is mainly generated from diesel generator sets. In this paper, an investigation has been made to find out total available potential of solar, wind and biomass in five islands of union territory of Lakshadweep. If we start generating up to the available potential then some islands will become renewable islands and this will increase the reliability, employment and decreases the cost of energy generation and pollution. Pearl and Logistic models have been used to find out the growth rate of SPV power generation. Using these models we find out that in how many years we will achieve the total available potential. After this, we have proposed a model of hybrid energy power generation for Kavaratti Island. The simulations and techno-economic evaluations have been done with the help of hybrid optimisation model for electric renewables software. Thousands of simulations have been carried out to achieve an optimal autonomous system configuration, in terms of system net present cost and cost of energy. Journal: Int.

Panel data analysis indicates that the effect of fossil fuel consumption on agricultural, manufactured and services exports is negative, while that of fuel export is positive. However, electricity has positive effect on the exports of three sectors, while its impact on fuel export is insignificant. Further, fossil fuel generates negative impact on manufactured and services imports, but positive and insignificant effect on agricultural and fuel exports respectively. The effect of electricity on sectoral imports is positive except for agricultural products where it is insignificant. The country level analysis reveals diverse effects of fossil fuel and electricity consumption across sectoral trade structure and the selected West African countries. The foregoing findings inform the articulation of some policy implications including the following. Energy conservation policy is required to encourage production and exporting of commodities with energy saving techniques so as to save costs, conserve non-renewable energy, and foster export diversification in the selected countries. Liberal import policy should be accompanied with energy conservation policy especially where inefficiency of non-renewable energy use is prevalent. Journal: Int.
