The article is aimed at developing strategic directions and introducing regulatory measures for the formation of Ukraine’s energy policy on the principles of energy saving and the development of renewable energy industry. On the basis of scientific works, the main organizational-economic vectors of energy industry sector development are systematized, which are associated with the formation of a favorable socio-political climate regarding the priority of using renewable energy sources in the fuel and energy complex; development of effective methods of both the State-based and the market-based regulation by the world community; coordination of the strategy of sustainable development of the world economy. It is determined that the energy saving policy should be based on a flexible combination of the State-based regulation and the market environment for the formation of the most acceptable stimulation mechanisms in the specific economic and political situations, which allows for the greatest economic benefit. It has been found out that the implementation of energy saving processes is impossible without the mass use of renewable energy carriers, which are a universal resource for processing to the right types of energy, are marked by energy independence related to obtaining economic benefits and contribute to the creation of an ecological friendly environment. In the perspective, the energy saving processes, the transition of the national economy to wide implementation in the production of high-tech technologies and the use of renewable energy sources should become the determining factors of Ukraine’s energy strategy.

Buildings with architectural constraints and recognized historical values require a careful design process, aiming to combine the needs of conservation and the adaptation of the buildings to the modern use and its accessibility. The feasible interventions consist in improving the energy performance of the building envelope, in inserting efficient technological systems and using renewable energy sources where possible. The compatibility between the architectural constraints of the building and its more sustainable future use represents a crucial challenge. This work presents the interventions designed and realized on a small villa located in the Prati district, in Rome. Starting from the requests of the client, the primary objective was to create a comfortable house both in the winter and in the summer season, with widespread use of automation systems for managing the utilities. In line with the current energy scenario, the interventions were oriented to energy efficiency, the reduction of polluting emissions, the electrification of utilities and the use of renewable energy sources. The proposed solutions showed high gains in terms of energy saving even if the changes to the building envelope were limited by the desire to preserve the values of the cultural heritage. Therefore, a virtuous refurbishment can effectively respond to current energy efficiency goals.

Saving Behavior

The pro-ecological and pro-saving behavior of households as energy consumersThe aim of the article is to indicate the changes related to households’ behavior linked to energy saving and pro-ecological activities. Therefore, the authors conducted acomparison analysis of the results of the nationwide Polish research about Polish ecological awareness and identified — as part of the Polish National Science Centre NCN project called “Modelling prosumers’ behavior on theenergy market” — pro-economical attitudes of households. The first part of this paper pre­sents the opinions of Poles about the possibilities of development of the different kinds of energy sources in Poland, taking into special consideration the development of renewable energy sources. In the second part of this paper the authors describe households’ behavior connected with saving energy. They analyzed pro-economical behavior such as: switching off lights in empty rooms, un­plugging phone chargers after use, using economical bulbs and unplugging devices that are not in use. The diversifying variables of behavior are: sex, age, income. The analysis of households’ behav­ior was supplemented with the analysis of pro-economical attitudes of Wroclaw university students.

Energy conservation or energy saving is one of the most important methods for reducing CO2 emissions, which is known to be associated with global warming. Although development of renewable energy sources such as solar or wind energy is necessary, we must first pay attention to the fact that enormous amounts of energy are consumed uselessly at present. Energy saving should therefore be one of the first problems to be tackled. It may not only bring reductions in CO2 emission, but also may lead to savings in expenditure on energy. This paper introduces some of the initiatives taking place in Japan aimed at energy conservation.

Utilization of alternative sources named as new and renewable energy sources; Due to technological development and difficulties in competing economically with traditional resources, it has not reached the desired level until today. Due to the rapid increase in energy consumption today; It is a fact proved by scientific findings that fossil fuels will be consumed in the near future. Therefore, in the development of countries; Providing timely, reliable, clean and uninterrupted energy, creating a market environment, in other words, successful implementation of energy management have become imperative. Energy has become one of the most important problems of the world countries today. As is known, the lifetimes of energy sources such as coal and oil are limited. In addition, due to the use of fossil fuels; It is a fact that global warming is increasing day by day. In the light of the data obtained, for our energy needs; alternative solutions should be found, renewable energy sources should be evaluated. The importance of renewable energy sources has increased as the problems related to environmental pollution increase, and projects related to them have started to get support. These energy sources can basically be classified as hydroelectric energy, wind energy, solar energy, geothermal energy, modern biomass energy and hydrogen energy. Economic and efficient operation of new and renewable energy sources should be transformed into a common understanding in order to provide clean energy. In this study, energy production methods from green energy sources, environmental relations and new technologies used with these energy sources are explained. It has been compared among energy sources; In Turkey, energy management issues are discussed, new and renewable clean energy use efficiency and energy saving and new strategies are determined. In addition, recommendations were made on energy use efficiency and energy saving measures in various sectors.

The paper shows that a comprehensive intersectoral approach is needed to address the issues of systematic management of energy saving in agriculture and to justify rational measures of economic support for the state-initiated introduction of energy-saving technologies, machines, and projects. Such requirements are met by the energy-economic (bioenergy) assessment method. The energy-economic assessment consists in comparing the costs of cultivating plants or servicing animals in single units of measurement with the production results and is mainly of national strategic importance. On the basis of such assessment, economic guidelines and incentives for the introduction of new energy-effi cient technologies, machines and projects, including the use of renewable energy sources, can be developed. The author presents an approach to improving the methodology of energy-economic assessment of agricultural technologies and projects when using renewable energy sources in technological processes. It is proved that in order to ensure the reliability of the energy-economic assessment associated with permanent technological and organizational changes and the digitalization of technology and economy, it is necessary to continue research to improve the assessment methodology, as well as clarify and regularly update energy equivalents.
