The purpose of this study is to define indicators areas of efficient use of resources in a circular economy, aimed at solving energy and environmental problems, as well as to develop theoretical and practical recommendations for their formation. This study defines the conceptual foundations of the circular economy, defines the methodological approach to energy efficiency in terms of alternative energy sources, and develops a theoretical and practical approach to balancing employment in the labour market in a circular economy. As a result of the conducted research using the principles of the circular economy, the category of efficient use of resources in the field of energy efficiency is defined. The scientific novelty lies in the use of a systematic approach to the study of economic phenomena, which revealed the consideration of the interconnection of all elements, as well as the study of individual economic objects as structural parts. The role of each part in the general functioning of the circular economy and its impact on individual elements are defined. The methodology of the study is revealed using methods of comparison, the concept of systems, and statistical approaches.

Introduction: The co-authors provide an overview of the main types of wind turbines and power generators installed into wind energy devices, as well as advanced technological solutions. The co-authors have identified the principal strengths and weaknesses of existing wind power generators, if applied as alternative energy sources. The co-authors have proven the need to develop an algorithm for the selection of a wind generator-based autonomous power supply system in the course of designing windmill farms in Russia. Methods: The co-authors have analyzed several types of wind turbines and power generators. Results and discussions: The algorithm for the selection of a wind generator-based autonomous power supply system is presented as a first approximation. Conclusion: The emerging algorithm enables designers to develop an effective wind generator-based autonomous power supply system.

The purpose of this paper is to analyze and research the legal mechanisms which make it possible to improve agroecology through the organization of cultivation of Jerusalem artichoke.Methodology. The methodology includes comprehensive analysis and generalization of available scientific, theoretical, practical and applied material and development of relevant conclusions and recommendations. During the research, the following methods of scientific cognition were used: dialectical, terminological, historical and legal, logical and normative, systemic and structural, functional, normative and dogmatic, generalization methods. Results. The process of analysis and research highlighted the possibilities of cultivating Jerusalem artichoke for improving agroecology, namely improving the ecological state of the atmosphere air and soil, preparing them for organic farming. The article contains examples of practical application of tubers of Jerusalem artichoke and herbage for the production of therapeutic and prophylactic products, alternative energy and highly efficient building materials. Scientific novelty. The study found that the authors summarized and systematized the levels of legal regulation in the field of using Jerusalem artichoke for improving agroecology, preparing soil for organic farming, in particular: the inter-sectoral level which covers the interaction of agricultural and environmental law in terms of cultivation and use of Jerusalem artichoke; the level of integrated environmental and legal regulation; level of individual resource (floristic) legal regulation; the level of environmental protection (anthropoprotection) legislation.Practical importance. The results of the study can be used in law-making and environmental protection activities related to issues of cultivating and using the Jerusalem artichoke as a means of improving agroecology.

This case study explores the strategic business opportunities, for Lane Crawford, an iconic luxury department store, to transition in a circular economy towards sustainability. A new experimentation framework was developed and conducted among cross departmental employees, during a Design Lab, with intention to co-create novel Circular Economy business concepts towards a new vision: the later was a reframe of the old system based on the principles of sustainability; to move beyond a linear operational model towards a circular economy that can contribute to a regenerative society. This work draws on both academic and professional experience and was conducted through professional practice. It was found that innovative co-created concepts, output from the Design Lab, can create radical change in a circular economy that is holistically beneficial and financially viable; looking forward to extract greater value a)Internal organization requires remodeling to transform towards a circular economy; b)Requirement for more horizonal teams across departments vs solely vertical; c)New language and relationships are required to be able to transition towards a circular economy; d)Some form of physical and virtual space requirements, for cross-disciplinary teams to come together to co-create; e)Ability to iterate, learn and evolve requires agency across the business

The One of alternative energy that is environmentally friendly is by untilize water energy and turn it into a Microhydro power plant. Microhydro power plant usually made from utilize the waterfall with the head fell. While utilization for streams with a head small drop is not optimal yet. This is a reference to doing research on harnessing the flow of a river that has a value of head low between 0.7 m – 1.4 m with turning it into a Vortex flow (vortex). The purpose of this research is to know  the effect variation number of blade on power and efficiency in the vortex turbine. This research uses experimental methods to find current, voltage, torque and rpm using a reading instrument. The materials research vortex turbine used 6 blade, 8 blade and 10 blade with flat plate. The result showed the highest efficiency is 29,93 % with produce turbine power is 19,58 W, generated on turbine with variation 10 blade with load 3,315 kg and the capacity of water 10,14 l/s. Followed with an efficiency 24,17% and produce turbine power is 15,81 W, generated on turbine with the variation 8 blade with load 3,315 kg and the capacity of water is 10,14 l/s. The the lowest turbine efficiency 22,32% with produce tuebine power 14,60 W, generated on turbine with the variation 6 blade with load 3,315 kg, the capacity of water is 10,14 l/s.

Strategy of successful development of the national economic systems of countries-leaders the last years is closely related to leadership in research-anddevelopments, by appearance of new knowledge, development of hi-tech production and creation of mass innovative products. Development of innovative potential is not only a way of dynamic development and success but also backer-up of safety and sovereignty of country, to her competitiveness in the modern world. The necessity of introduction in Ukraine of європейських standards of life and exit of Ukraine on leading positions in the world defined the aim of Strategy of steady development «Ukraine 2020» approved by Decree of President of Ukraine № 5/2015 from January, 12, 2015 and plans of operating under implementation of Agreement about an association from ЕС, by the obligations of Ukraine in relation to the achievement of national Aims of steady development on a period 2030 to The basic displays of origin of economic deprivation and destructive deviation of innovative development of enterprises, lighted up questions that touch maintenance and ways of improvement of strategic management of enterprises innovative activity in the system of institutional structure of forming of innovative behavior, are certain in the article. Reformation of economy of country must take place in the conditions of maintenance of certain calls and risks, in particular, it is a threat of escalation of the battle operating on east, authenticity of worsening of the external economic state of affairs on world commodity markets, migratory processes, braking, destructive deviation and депривація of investment activity. A human capital, and also knowledge and results of scientific researches, must become basis of the Ukrainian innovative competitiveness.
