The article deals with financial and economic meaning of bioenergy as an important component of the country’s energy security. The problem of transition to renewable energy sources, in particular biofuels, was investigated. The relevance of research is that biofuels can fully replace traditional energy resources, increase the level of economic efficiency of production and competitiveness of national economy, as well as reduce amount of harmful emissions into the environment. The purpose of research is to study and develop theoretical and practical principles of financial and economic development of bioenergy and its role in ensuring energy independence of Ukraine. In the context of financial and economic crisis and political instability, the development of bioenergy industry is of priority in dealing with main social and economic problems. One of the main aspects of bioenergy development is states’ concern and use of targeted state funding. Moreover, other perspective ways to implement bioenergy technologies in Ukraine are public private partnership and attraction of foreign direct investments. Economic assessment of different ways of full or partial replacement of natural gas has shown that they can be supplied with biomass, while the total capacity of introduced objects according to the bioenergy development program can save natural energy resources. According to the formula of the method of average medium, the forecast of optimistic and pessimistic scenario of energy potential development is developed. Energy independence of Ukraine can be ensured through effective implementation of alternative energy with full state support, which will lead to acceleration of economic development of the territories, increasing level of life of people and environmental security of the country.

In the article, the essence of the concept of a banking institution “capitalization” is revealed. The current state of capitalization level of domestic banks is investigated. The directions of strengthening the capitalization are offered, which will increase the com¬petitiveness of domestic banking institutions in the world financial market and will ensure the national economy stability on the way toward integration into the world economy.It is proved that the prospects for the development of any bank are largely determined by its capitalization level. Lack of proper development inhibits both individual banks and the banking sector as a whole.In the context of the recent financial crisis, the provision of sufficient capital for banks has been one of the key issues, because the lack of capital was the greatest threat to the banking system stability. With this in mind, the issue of the banking system capitaliza¬tion is particularly topical.Today, the development of the Ukrainian banking system under economic instability has faced the increase in competitiveness of domestic banks compared with foreign ones, in order to preserve the national priorities of the banking system in general under conditions of foreign capital movement.The processes of concentration in the banking system of Ukraine are analyzed using Herfindahl-Hirschman index in terms of assets and equity, allowing to estimate the level of monopolization and, therefore, the impact on economic development. To con¬sider the increase in the level of capitalization and reliability of the banking institutions of Ukraine, it would be advisable, first of all, for banks to improve the quality of capital and to ensure a sufficient level of coverage of risks taken by banks.
