Abstract
This article aims to show the areas in which technological changes will take place to bring about energy security, and the prerequisites and costs. It has been assumed that technological progress will contribute to the development of energy markets and increase the level of energy security. Changes in energy markets are a necessity. Energy is a source of economic competitiveness. The ability to produce cheap energy and in quantities adequate to needs is a social and economic development factor. The opportunities for change will be the need for new energy sources, instability in the energy markets, as well as technological progress. New technological solutions allow for better energy demand and supply management and preparing forecasts for increases/decreases in the energy demand. The threats are high costs of introducing new technologies and the necessity of implementing many investments at the same time, which require changes in entire systems. Investments require a long period of time and anticipation of trends.
