Use of Wastes of the Livestock Industry as a Possibility for Increasing the Efficiency of AIC and Replenishing the Energy Balance

There are several reasons for the economic and social necessity in forming and developing the biofuels market of Ukraine, starting with energy security considerations, diversification of national production, support of innovations and ending with economic and social efficiency of biofuels market development on the basis of high motivation for the agrarian sector growth, positive social bias towards rural population growth and environmental security through renewable energy. The immediate prospect of energy autonomy for agro-industrial production should be based on efficient production and use of biomass. At present, biomass is the fourth largest fuel in the world, producing about 2 billion tonnes of conventional fuels per year, which is about 14% of the world’s total primary energy consumption. In some countries, this figure is even higher, but in Ukraine it still does not exceed 3%. This will help Ukraine reduce its dependence on energy imports, halt its transformation into a raw material appendage, and enable processing of such a large-scale resource while obtaining hundreds of thousands of jobs, income for the citizens and for the state budget. At this stage of state development, biofuel production is one of the determining catalysts for new global trends in Ukraine’s agro-industrial complex that will contribute to its sustainable development.

Linkages between Respiratory Symptoms in Women and Biofuel Use: Regional Case Study of Rajasthan, India

Women in low and middle-income countries predominantly use biofuel for cooking, resulting in potential adverse health outcomes. In India, it is estimated that about 40% of total primary energy consumption is in the domestic sector with biofuels alone accounting for about 75% of domestic energy consumption. This study assesses linkages between wood consumption and perceptions of women’s health, combining results from a rapid assessment of eight rural districts in Rajasthan with a regression analysis of data from Rajasthan State (sample size 41,965 women) from the Demographic and Health Survey 7 dataset (2015–2016). The results of the rapid survey indicate that women who cook with biofuels perceive adverse health outcomes. Educational level, income, and age have an impact on fuel consumption and clean fuel purchased. The regression model drawing upon data on women at a regional level in Rajasthan yielded significant results suggesting a strong association between fuel type and symptoms of respiratory infection controlling for age and education. This research is timely as it provides valuable evidence for India’s Ujjawala Scheme which has the mandate of providing LPG connections to women from below the poverty line.

A Novel Method for Optimizing Fractional Grey Prediction Model

Aiming at the shortcoming that the classical FGM(1,1) model regards the gray action quantity as a fixed constant, the DGM(1,1) model is used to dynamically simulate and predict the gray action quantity, so that the gray action quantity can change dynamically with time. On this basis, a new FGM(1,1,b) model with dynamic gray quantity change with time is proposed, and the total primary energy consumption in the Middle East is taken as a numerical example for simulation prediction. The results show that the prediction accuracy of the dynamic FGM(1,1,b) model proposed in this paper is higher than that of the classical FGM(1,1) model, and the practicability and effectiveness of the FGM(1,1,b) model are verified. At the same time, it also provides relevant theoretical basis for the study of world energy development.

Forecasting the Energy Embodied in Construction Services Based on a Combination of Static and Dynamic Hybrid Input-Output Models

The energy embodied in construction services (EECS) to increase industrial production capacity, contributes to total primary energy consumption (TPEC) in developing countries like China. Forecasting EECS is important for creating energy policies, but has not received enough attention. There are some defects in the main two methods of EECS forecasting: the static hybrid input-output (HI/O) model and the dynamic HI/O model. The former cannot identify the quantity of construction services, whereas the latter is unstable for EECS forecasting. To tackle these problems, we propose a new model, which is a combination of the static and dynamic hybrid input-output model (CSDHI/O model), for EECS forecasting. Taking China as a case study, we forecast the EECS and TPEC of China until 2020 and analyze the sensitivities of four influencing factors. The results show that the EECS of China will reach 1.79 billion tons of coal equivalent in 2020. The improvement of fabrication level is identified as the most important factor for conserving both TPEC and EECS. A sudden drop in gross domestic product (GDP) growth rate and decreasing the investment in the service industry can also restrict EECS growth.

Covering of heating load of object by using ground heat as a renewable energy source

Rational use of energy, improving energy performance of buildings and use of renewable energy sources are the most important measures for reducing consumption of non-renewable primary energy (solid, liquid, and gaseous fuels), environmental protection and for the future sustainable development of mankind. In the total primary energy consumption great part is related to building industry, for heating spaces in which people stay and live. Renewable energy sources (RES) present natural resources and they are one of the alternatives that allow obtaining heat for heating buildings, and by that they provide a significant contribution to the energy balance of a country. This paper analyzes the participation of ground source as RES, when the vertical (the probe in the ground) and horizontal (registry in the ground) heat exchangers are used for covering heating load of the building.

Challenges and Opportunities for Bio-Diesel Production in Turkey

This paper will discuss the main challenges and opportunities for sustainable production of bio-diesel fuel in Turkey. Turkey's energy demand has risen rapidly as a result of economic and social development over the past two decades. As in many other countries, Turkey is heavily dependent on fossil fuels to meet its energy requirements. Fossil fuels account for approximately 88% of the country's total primary energy consumption. Turkey imports three major sources of energy, and its dependence on imported fossil fuels is expected to increase even further. At present, Turkey's oil production met only 7% of demand, the rest was imported. In spite of Turkey's heavy dependence on fossil fuels for energy demand, the country has a large potential for development of renewable resources of every type. Bio-fuels can provide an opportunity for Turkey to decrease its dependence on foreign oil, eliminate irregularities in agriculture, create new employment opportunities, decrease rural depopulation, and sustainable energy development. Turkey has a large area of suitable agricultural land for the production of bio-fuel crops. Unfortunately, only about 4–5% of total cultivable area is used for cultivating bio-fuel crops. The vegetable oil sector, which is considered to be one of the strengths of the Turkish agriculture and process industry, could be reformed to meet bio-diesel production demands.
