Abstract
The article presents the role of the "shale revolution" in Estonia which significantly increases the energy security of the country. The purpose of this paper is to show how significant are the changes triggered by generating energy from oil shale in Estonia. The benefits gained from oil shale since a hundred years have been considerably enhanced by technical progress. As a result of introduced innovations Estonia is able to practically fully satisfy its oil and electricity needs by processing shale. The article also outlines actions undertaken to tackle the problem of harmful emissions arising while generating electricity from shale. Further aspect analyzed in the paper is the impact of oil shale industry in Estonia on the relations with other countries, with Russia in particular.
