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 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.

Abstract The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy efficiency, as well as actions aimed at increasing society’s awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was “the age of steam” or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientific and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy efficiency. The development of high-efficiency technologies that reinforce energy security is presented, with it being assumed that these new high-efficiency technologies are capable of being applied globally in the near future.

The increase in population and industrialization has increased the consumption of electricity. Currently, it is impossible to live without electricity. Indeed, it is necessary for the economic, social and industrial progress in all the countries of the world. This is why we are always asked to develop all types of energy to produce clean and safe to improve energy efficiency. Indeed, the use of new renewable energy sources helps to mitigate greenhouse gas emissions and dependence on centralized energy sickles. The difficulties of renewable energy-based power systems lie in their production, which is not controllable and may not meet the increase in energy demand.

Public Views

Recent worldwide growing awareness of the global climate changes stressed the importance of developing and supporting the renewable energy sources (RES). However, the public support for RES varies across various countries and regions, especially those abundant in traditional fossil fuels. This paper presents the analysis of the public views of the economics of the renewable energy using the results of the online survey (N = 750) conducted in several regions of the Russian Federation, a country abundant in natural gas and oil. Our results indicate that there is a mixed opinion on trust in RES as opposed to the traditional energy sources. Even though we found some support for the renewable energy technologies, it appears that it is correlated with the respondents’ concerns about the environmental protection and sustainable development as well as with some demographic variables. The outcomes of the regression analysis confirmed that positive attitudes towards climate protection predetermined the support for various types of RES, while the financial or political gains did not come through as significant. The results indicate that public views on the renewable energy sources could and should be shaped by the information campaigns and presentations in mass media conducted by relevant policymakers and public authorities.

Greening the economy requires green innovations, and innovations require investments. Most countries of the world are still relying on conventional (fossil-based) sources of energy. The transition toward green or renewable energy sources is an effective and innovative way to meet ever-increasing demand as a result of the rising population. Another reason for innovations in the field of green energy is the need to mitigate climate change and avoid pollution, especially in developing countries. The monitored investments into renewable energy sources are usually public. Therefore, this paper aims to determine whether the selected countries of the world produced renewable energy efficiently, considering the investments made by public financial institutions and installed electricity capacity for renewable energy sources, for the period 2013–2017 (for a deeper analysis, the year 2017 was chosen). For this purpose, the Stochastic Frontier Analysis model in the logarithmic form of the Cobb-Douglas production function is used, which helps to judge the competitiveness of countries based on effectively transforming the inputs into outputs. Results suggest that the effect of the first variable “installed electricity capacity” on electricity generation was highly statistically significant, and the impact of the second variable “public investments” was characterized as statistically insignificant. The monitored countries were divided into 10 groups according to the different range of estimated output-oriented technical efficiency from 0.00 to 1.00. Most countries should increase the renewable electricity generation approximately by 40-49%, given the level of inputs (16 countries of 6th group with estimated output-oriented technical efficiency 0.51-0.60) for the year 2017.

Environmental pollution, in particular atmospheric pollution, is largely associated with the production of thermal energy. Suspended dusts and chemically aggressive gases generate a significant danger for as well human health as biosphere. In recent years there has been a growing conviction about decisive impact of greenhouse gasses emission generated by the economic and civilizational activity of humanity on global climate changes. Hopes of breaking these adverse trends is connected with the mass use of renewable energy sources or rather so called ecological energy sources, that are relatively less environmentally aggressive. The quantitative comparative assessment of their negative impact on the environment is important in the proper classification of energy sources. Comparing of quantities of emitted suspended dusts and aggressive gases including greenhouse gases is good parameter for evaluation of air pollution. In Polish conditions, atmospheric pollutions are predominated by products of coal combustion. A good indicator of the ecological quality of energy sources is therefore the reduction of emitted harmful substances as a result of coal substitution. In this work examples of ecological effects of geothermal installations have been presented. Geothermal energy is generally considered to be renewable and ecological, while the substitution of coal fuels by hydrocarbons, including natural gas, is more problematic. The comparative analysis performed for a single-family house shows a radical reduction in the emission of suspended dust and chemically aggressive gases associated with replacing the coal furnace by natural gas-fired boiler and reducing the emission of carbon dioxide by half.
