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.

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.

The article shows that the urgency of the fuel and energy problem determines the need for rational energy consumption in all sectors of the economy, including agriculture. A comprehensive cross-sectoral 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 introduction of energy-saving technologies, machines, and projects on the part of the state. It is shown that the energy-economic (bioenergetic) estimation method meets these requirements.. The main advantage of the energy-economic assessment is that its application makes it possible to compare in single units of measurement (regardless of the historical period or the state, the current market situation) the costs of cultivating plants or servicing animals with the results of production and is mainly of national strategic importance. An approach to improving the methodology of energy-economic assessment of agricultural technologies and projects when using renewable energy sources in technological processes is presented. It is proved that in order to ensure the reliability of the energy-economic assessment in connection with the constant technological and organizational changes and the digitalization of technology and the economy, it is necessary to continue research in the direction of improving the methodology for assessing, clarifying and regularly updating energy equivalents.

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.

Near Term

Because of the near-term risk of extreme weather events and other adverse consequences from climate change, and, at least in the longer term, global fossil fuel depletion, there is world-wide interest in shifting to noncarbon energy sources, especially renewable energy (RE). Because of possible limitations on conventional renewable energy sources, researchers have looked for ways of overcoming these shortcomings by introducing radically new energy technologies. The largest RE source today is bioenergy, while solar energy and wind energy are regarded as having the largest technical potential. This paper reviews the literature on proposed new technologies for each of these three RE sources: microalgae for bioenergy, photolysis and airborne wind turbines. The main finding is that their proponents have underestimated the difficulties facing their introduction on a very large scale.
