Considering the critical amount of power consumption in public buildings, sustainable energy use in the workplace can present an opportunity to tackle the worldwide problem of climate change. A systematic literature review revealed that, though the majority of scientific papers emphasize the importance of appliances and new technologies, human behavior in this area is not less significant. It can contribute to the reduction of energy use and CO2 emissions and address a number of environmental issues. The main purpose of this work is to analyze and compare the research performed on the topic of the determinants of sustainable energy consumption and investigate their impacts on the behavior of employees in three public buildings in Greece. The questionnaire survey discloses that, despite the organizations paying the bill, the employees believe that saving energy at work is important. The results also show that female employees feel more responsible for energy problems, such as the exhaustion of energy sources or global warming. Finally, a regression analysis affirms that the willingness to save a substantial amount of energy at the workplace is greater when employees have higher personal norms, that is, they feel morally obliged to consider the environment and nature in their daily behavior.

Tourism is an important sector of economy. Tourism destinations compete with each other seeking to attract more tourists, because their spending has positive impact on the economy. Therefore, the competitiveness of tourism destinations became an important issue of scientific researches. City may be considered as tourism destination. The competitiveness of the city can be defined as the ability of the city to highlight its local tourist attractions and provide goods and services for tourists better than other cities do. Events may be considered to be a factor of city tourism competitiveness because they can attract visitors to the city and encourage them to spend money, which makes significant economic impact on city tourism and the economy. Seeking to evaluate the economic impact of an event as a factor of city tourism competitiveness, the primary data sources should be used, paying attention to the expenditures of new visitors, excluding expenditures of "time-switchers" and "casuals".

Scientists from all over the world recognize that saving energy in households is currently a very relevant topic. Energy resources are a very important factor for each country's economic vitality. Not only the country's replenishment in energy resources is important, but also the reduction of energy consumption volume. The Objective of the study: to assess the energy savings in households potential, applying the measures aimed at the behavior change of the population through energy-saving direction. Methodology: yhe impact of behavior change of the population measures is assessed according to the criteria of efficiency and effectiveness. In order to assess the potential for energy savings in households, the following methods, such as an experiment, the control group formation scenario, household questionnaire, were used. The questionnaire was designed to supplement the experiment, in order to gain deeper knowledge of the household, to obtain more detailed information about the nature of the behavior, to identify barriers to behavior change, and to select a control group of households to carry out the experiment. Data, results and main contribution of the paper: research shows that people's behavior related to energy saving is influenced by a number of macro-level and micro-level factors. In the article, the assumptions of the changing behavior of population are analyzed and the specific measures aimed at the behavior changes of the population selection and implementation impact assessment.

In this paper the energy saving behavior and its impacting determinants in schools are analyzed. There is a large number of research on energy saving behavior in residential buildings. However large fraction of the total energy is consumed in public buildings and schools. The issues of sustainable energy consumption behavior are less studied in these types of buildings. Based on the research on energy consumption in residential buildings the determinants of sustainable energy consumption in schools were classified into three groups: psychological and social; socio-demographic and economic determinants; and contextual determinants. A systematic literature review was conducted for the substantially less investigated schools in terms of efficient energy consumption. According the review of research papers, the most important determinants of energy consumption in schools in terms of their influence on consumption were identified: attitudes; incentives/intentions/motivation; knowledge; awareness.

Sustainable energy development has attracted attention worldwide, partly because of the value chain of the wind energy industry that focuses on the overall value creation and innovation. In order to achieve not only ambitious goals in the fight against climate change, but also to create significant economic benefits for European Union citizens, it is necessary to ensure the production of renewable energy components in Europe itself and in Lithuania at the same time. This paper aims to evaluate the competitiveness of Lithuanian companies that manufacture wind energy components. The research was conducted applying methods such as a survey of manufacturers of wind energy components, expert assessment and descriptive analysis. The results of the competitiveness assessment revealed that the existing conditions and trends are favourable for the development of their performance and strengthening of their competitiveness. The government solutions to promote industry could facilitate the performance of companies operating in the value chain of wind energy components and encourage new companies to join it. This would encourage the Lithuanian industry to expand its participation in the value chain of the European Union’s renewable energy industry, create more jobs, and increase the added value.

For this paper, the authors theoretically analyzed the determinants of energy saving and sustainable energy consumption in schools. Much research exists on energy-saving behavior in residential buildings. However, there is a lack of focus on public buildings and schools. A systematic literature review was conducted in order to construct the theoretical background for the research of school buildings, which are substantially less investigated. The determinants of sustainable energy use in schools were grouped together into three groups: (i) psychological and social, (ii) sociodemographic and economic, and (iii) contextual. The influence of these determinants on energy consumption was investigated empirically by conducting a questionnaire survey in a vocational school in Greece. The results reveal that the intention to save a substantial amount of energy in a vocational school in Greece is greater when students feel morally obliged to consider the environment and nature, believe that it is in their power to avoid unnecessary power consumption, and are positively influenced by teachers, classmates, and other important people in their lives.
