This article attempts to identify and analyze the factors influencing the shaping of regional energy policy in the West Pomeranian Voivodeship, with particular emphasis on the potential for the development of renewable energy based on biomass. The aim of the publication is to determine the potential for the development of biomass resources, taking into account the criteria of sustainable development, i.e. economic, ecological and social aspects. So far, few researchers have dealt with this subject in a comprehensive way, and so far there has been a lack of detailed research on the potential of biomass in the West Pomeranian Region. The presented analyses are an important contribution to the development of knowledge about alternative energy sources in the energy sector. The research material used in the article comes from various sources, both domestic and foreign, including empirical data from scientific institutes of energy and fuels and regional institutions dealing with energy.
Sustainable development of separate regions and countries is affected by array of factors among which energy security plays a cricial role. We claim, that efficient use of energy is very important constutuent of energy security. The first part of the presented paper we wil devote to overview of perception of energy security and revealing waht role energy efficiency plays. Energy efficiency could be estimated by energy intensity indicator, which shows what ammount of energy is used for e.g. one European Euro. This indicator can be calculated for main sectors of economy: various branches of industry, services and agriculture. The higher value added is created in the sector, or, to put it in onother way, the higher activity of sector, the more important that energy in this sector would be used efficiently. In this paper we tackle longterm activity and energy efficiency of agriculture sector in developed and less developed countries.We raise an assumtion that in better developed countries activity of agricultural sector in long-run would diminish, what would be followed by gradular increase in energy intensity; i.e. energy intensity indicator would gradually diminish. Besides, we assume that those tendencies would be slightly different in currently less developed countries; i.e. agricultural sector not necessarely would contract and energy intensity would diminish with higher rates if to juxatopse with better developed countries. In order to verify raised assumptions data of the selected European countries will be used. Better developed countries would be represented by one country – Germany. Less developed European countries would be represented by Bulgaria and Romania. We will forecast activity and energy intensity by using LEAP software. Indicated data for chosen countries will be forecated untill year 2050. Obtained results will indicate if consitent patterns could be traced and respective policy implications formulated.
Energy security is conditioned by numerous factors, among which solutions and patterns of energy storage play important role. Electrical energy storage (EES) is the process by which energy is stored from the power network to a form which can be used later when converted back to electrical energy. There are various ways by which electrical energy can be stored for future purposes. Nowadays, the electrical energy is mainly stored in pumped hydroelectric energy storage (PHES) that comprises about 99% of EES worldwide and the battery energy storage (BES) that uses chemical energy with both methods yielding characteristic advantages and disadvantages. Electrical energy is mainly stored when there is low demand and when there is high generation of power at low costs. The energy is then used when there is high demand of power and the generation cost is high or when there are no other means of generating electrical energy. Electrical energy storage has many uses such as in the electrical devices, motor vehicles and stationery energy resources and is gaining special attention with the widespread usage of renewable energy sources (RES).
In this paper, we are focusing on the sustainable development of the electrical energy storage. We are drawing a comparison of the advantages and disadvantages of pumped hydroelectric storage and batteries that use chemical energy and assess their implementation based on various scenarios of the future development. We conclude that although HPS is still the more economical option, new advances in BES might alter the energy market and change the rules of the game by fostering the sustainable development through the more effective storage and transportation of electric energy.
Presented paper aims to indicate what types of interrelationships between energy usage patterns prevailing in particular country, economic growth and finally, sustainable development could be distinguished. The topic of paper, or, rather research area, is neither new nor original. Nevertheless, an array of approaches towards character of considered interrelationships can be encountered. Complicity of chosen issue, we reckon, lies in differences of perception of the following questions. Our findings consequently would depend on, at first, how we measure economic growth in short and long terms, the second, how we measure energy security, and, the third, how we benchmark progress towards sustainable development. Methods, which we consider as being applicable for measuring of selected interrelationships, comprise a separate part of scientific elaboration. Therefore we formulate a task to overview the most contemporary measurable perceptions of economic growth, perceptions of energy security facets affecting economic growth and consequent reaction of sustainable development to various scenarios of energy consumption and economic growth. Resulting conclusions about measurement of indicated phenomena and argumentations of their plausible interrelation would lead us to choice of methodological approaches of described interrelations’ analysis.
The purpose of this paper is to investigate how learning in collaboration can support the development of sustainability competence in the military. The concept of sustainability in the military is controversial; nevertheless, requirements for more conscious decisions regarding economics, environment and society issues enter military practice and require rethinking the processes of military education and development. The application of computer-supported collaborative learning brings new opportunities in overcoming controversy of sustainability in the military and at the same time puts forward the solutions and skills for implementations of sustainability in the military.
Instead of using traditional approach towards sustainability as an interaction of the following three components: economic viability, social welfare and environmental protection, we described sustainability in the military as a composition of mission, management of installations and stakeholders, operations and maintenance, environment protection and quality of life. According to these categories, e-learning platform was developed. The core of this platform is the formal learning curriculum, which serves as a shell under which a variety of practices can be introduced to address the desired training objectives. The complex solution was accomplished with computerfacilitated collaborative learning that enables teem-working, collaboration and peer-assessment. Computer-facilitated collaborative learning supports social interaction in the learning system and sustains group-work within a variety of decision-making frameworks. Those features of the learning system are very important considering the controversy and complexity of sustainability in the military.
