In this article, the authors present the results of research undertaken in relation to the situation regarding renewable and non-renewable energy reserves in the European Union, as well as the way in which this energy is consumed. The general view presented regarding energy resources around the world is that oil, natural gas and coal are being exhausted at an alarming rate and if we continue to exploit these oil resources at our current pace, we will see a massive depletion in energy resources over the next 41 years. The authors also focus on representing the intensity of greenhouse gas emissions from energy consumption, demonstrating that it has shown a slight decrease in the European Union. The resources and consumption of renewable and non-renewable energy were analyzed in close interdependence with these indicators under study, such as final energy consumption, renewable energy and total energy production, in order to give a correct interpretation of how these resources are used. At the same time, starting from the fact that the world economy is currently facing a cluster of crises (pandemic, financial-economic, energy, general resources), it was deemed important to highlight the fact that the total production of energy demonstrated an oscillating trend during this period.

The COVID-19 pandemic crisis, which was triggered in 2019 with oscillating evolution in 2020 and 2021, was a factor that has had dramatic effects on the economic growth of countries worldwide. In the context of the pandemic crisis, population health has deteriorated; education and economic activity in all the countries around the world have been affected. The main purpose of this paper is to highlight the special situations that humanity is experiencing as a result of the unprecedented effects that the COVID-19 crisis is having on the socioeconomic evolution. Specific statistical econometric methods (such as analysis of linear correlations, multiple linear regression, analysis based on dynamics indicators, and spectral analysis, comparability based on indices) were applied to highlight the evolution and future prospects of the COVID-19 virus worldwide. The COVID-19 crisis has generated another major issue for mankind, along with global warming and the energy transition, namely, population health. For this reason, in this study, we focused on the impact of the COVID-19 crisis on population health in a broader context; the sustained growth of populations in developing countries and aging populations in developed economies.

Blockchain is a concept that tends to revolutionize the world of finance in a technological leap that allows fast, secure and decentralized transactions. The Blockchain technology is used in virtual coins (bitcoin) conditions, with a high innovation potential, applicable in various areas, with the advantage of storing databases, resulting in an unprecedented level of transparency in the private or public area. Interestingly, under the bitcoin conditions, the black chain system uses a decentralized peer-to-peer payment system. Practically, the bitcoin can be considered as the most appropriate triple game accounting system. All of these considerations are developing in the big data era, which is defined as a large, diverse, high-volume information base requiring new forms of processing. Big data is important for businesses because based on these, strategic and marketing decisions can be made to optimize the activity in the market conditions and consumer preferences. European Union directives provide for measures to ensure the development of all states and, in this context, the community. At the same time, some measures provide for a more accelerated development for states with a low accession. For this, funds have been made from which important amounts are allocated to these states. The complex development of the European Union aims, in fact, to improve the quality of life (standard of living) in all Member States. At the European community level there are databases usable in economic analyzes. Also, Eurostat is the institution with the most complex databases. Recently, the Conference of the Directors of the Institute of Statistics in the European States analyzed the perspective of calculating the indicators in the context of the big data to be implemented. The article focuses on the concrete study of the use of large data in the calculation of the indicators that underlie the comparability between the EU Member States.

The economic growth of the national economy, within international bodies, as well as in the European Union, is a priority under the present conditions. Capital placement in geographic areas is based on effective opportunity studies. Such an analysis involves access to databases that satisfy the criteria for selecting the place of investment. At the same time, the media interested in attracting national or international investments can take such a decision on the basis of the data that will lead it to the optimal decision. Usually study of the market and the investment fields is insufficient and as such the effectiveness of the project is reduced. Under the very big data base, investors will have the chance to have information that needs to be used in a short time, and such opportunities need to be endowed with ultra-modern information systems. The issue of national and international investment is of utmost interest for any Member State of the European Union. In this respect, major projects will be developed involving as many member countries as possible, provided that everyone has the supremacy (to provide benefits) in a particular project sub-domain. Only specialization can provide the path to a viable and yet prolific economic and scientific cooperation. Through its directives, the European Union pursues both the individual development of each country and, above all, the complex development of the whole of the Union. In the big data era, investments, attracting them or entering into intra-Community economic cooperation provide a much faster course.
