The article examines the preconditions for the aggravation of environmental danger for Ukraine and the world as a whole, in particular in the context of the intensifying economic crisis. The long-term plans of the International Energy Agency to achieve “zero” carbon emissions by 2050 have been assessed. It was found that in order to ensure the growth of the world economy by the middle of the XXI century, it is necessary to increase energy efficiency, in particular in terms of active use of renewable energy sources. Energy efficient measures to ensure energy security of the urban agglomeration are summarized. In order to develop alternative energy sources, investments are needed in the energy sector (the annual share of investments in renewable sources in 2020 was 38%, which is $258.9 billion). Enhancement of energy efficiency and introduction of renewable energy sources should take place in the context of modernization of energy infrastructure of urban agglomerations: financing of technical re-equipment of energy assets, development of energy networks, reduction of energy intensity of industrial products, introduction of energy audit, etc. Ukraine has been ranked 8th in the world as one of the most attractive markets for renewable energy investment, but long-standing debt and incomplete energy market reform do not fully realize the potential (this is adversely affected by political mistakes, populist decisions, corruption and poor quality of energy management in Ukraine). It is proved that in the way of ecological safety creates barriers and a difficult situation with environmental protection, which significantly reduces the quality and comfort of life. It is proposed to create a strong environmental infrastructure in order to increase environmental security in the context of ensuring economic security; to introduce innovative ecological technologies; rationalize the processing of solid waste; to build modern waste processing plants, etc. Environmental legislation and governance in the field of energy policy is, unfortunately, a problematic area of current global change initiated by the EU to promote the use of environmentally friendly energy among EU member states.

Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes.

Originally, coal was the main source of energy. It remains so throughout the 18th century during the period of the rapid industry development. Later on, oil and naphtha began to be used as energy sources and their usage expanded especially in 19th century. A special feature of the above mentioned fossil fuels is their long creation period – requiring millennia. They are a result of rotting of different plant and animal kinds. In comparison to the period of their formation, the period of their utilization is far shorter. In accordance with a number of existing statistics about 2050 year it may be talked about a depletion of the liquid fossil fuels, also, the world coal supplies are considered to last within the next 200 years. Therefore, the development of nuclear power engineering is considered to be one of the alternatives to generate energy. Recently, the nuclear power energy generation has been denied in many countries because of the risks associated with its generation and because these risks have been confirmed by serious accidents throughout the World. The storage of worked nuclear waste is also a problem and risky. The renewable energy sources are another possibility to generate energy.

The energy sector holds a crucial strategic importance for development and its sustainability. However, the energy reserves in Turkey are insufficient for the increasing energy demand. For this reason, the need for alternative energy sources has emerged. The fact that fossil fuels used in energy production will be exhausted and their damaging effects on the environment has made it inevitable for the world to use renewable energy. In Turkey, the following are the main energy sources used in electricity production: hydraulic sources, brown coal, natural gas, coal and fuel oil. The use of renewable energy sources in electricity production has shown a considerable development in the world over the past few decades. However, these energy resources have yet to be exploited to any large extent in Turkey. In this chapter, the range of potential renewable energy resources available for electricity production in Turkey will be analyzed in order to determine the necessary technical substructure to make these renewable energy resources more attractive.

Environmental pollution, energy supply and security of supply have become major issues across the world due to climate change, limited energy sources, energy price volatility and energy supply constraints. Energy availability, energy efficiency and the replacement of fossil fuels by renewable energy sources are key factors in the global development of sustainable energy. In many countries with limited fossil fuel resources, the sustainable development of renewable energy sources is an important tool in reducing dependence on imported fuels. Some alternative energy sources, such as wind, solar, tidal and hydropower, seem almost inexhaustible. With the exception of tidal energy, all of these sources have been used extensively and for a long time. This article examines the improvement of energy security and the government’s actions to promote the use of renewable energy sources, focusing on increasing energy efficiency and reducing energy intensity and dependence on energy imports in Lithuania. In addition, the article provides the state of renewable energy sources in Lithuania, aspects of sustainability and future development directions and perspectives.

Introduction. The study of the development of CO2-neutral economy shows that this concept was only examined from a theoretical point of view in the first phases and has become a priority development area of all countries of the world since 2019. Carbon neutrality means not only a massive conversion of traditional energy into renewable (alternative), but also a complete thermal modernization, a change in the production sector towards energy saving and energy efficiency, innovative changes in wastewater treatment systems and recycling, etc. In other words, an important engine for the development of a CO2-neutral economy in the national economic system is a set of mechanisms and instruments to improve energy efficiency through sustainable innovative development. Theoretical base. For a detailed analysis of the conditions for the development of the energy efficiency of the national economy (Charles, 2019), it is necessary to monitor the state of the energy system and the environmental situation in the country (Huang, 2019), since today almost all countries of the world have reconsidered their priority areas in the development of the energy sector and have actively started to implement reforms for modernization and conversion towards energy production (Khan, 2018). The most promising areas were alternative energy sources and the development of a carbon-neutral economy (Jiahai, 2019). Therefore, the countries of the European Union have agreed on an action plan for energy efficiency for the period 2007-2020 (Kraemer, 2020), which is a 20-20-20 plan - reducing CO2 emissions by 20%, improving energy efficiency by 20% and increasing the share of renewable sources in the energy sector by 20% (Lakshman, 2019). In this phase, Russia plans to achieve 11% of renewable energy sources in the structure of final energy consumption and increase energy efficiency by 9%. At the same time, Russia, which has joined the Paris Climate Agreement (Rehbein, 2020), has set itself the goal of reducing CO2 emissions by 40% by 2030 compared to 1990 (Shu, 2019). The aim of the study is to develop theoretical and methodological tools for assessing the level of energy efficiency of the national economy and its main determinants. Results. The forecast results showed that there is a significant discrepancy between the optimistic and realistic scenarios of the dynamics of changes in the economy’s diverging sub-index of energy efficiency. According to the optimistic scenario, the balancing of the convergent and divergent sub-indices will take more than 10 years (in 2020, the value of the convergent sub-index of energy efficiency of the national economy was 0.84 and the projected value of the divergent sub-index in 2030 was 0.71). Conclusions. The growth of the economy’s integral energy efficiency index is possible if a stable balance is achieved between its convergent and divergent determinants. Calculations have confirmed that the implementation of state policies to ensure the energy efficiency of the economy should primarily focus on increasing divergent determinants of the energy efficiency of the economy. To target the diverging sub-index of the national economy’s energy efficiency, the paper performs a scenario forecast of the vector of its change based on the Brown model, which takes into account the retrospective nature of the distribution of its time series and eliminates fluctuations in random variables.
