Abstract
The energy security is one of the main goals of the European Union states. To secure the energy transform from natural gas have many aspects and nowadays the environmental aspects are important too. The main aim of this paper is to describe the new  natural gas pipelines from Russia (Nord Stream, Blue Stream, South Stream), Middle East (Nabucco)  to West Europe. Other forms to get natural gas are from the Liquidized Natural Gas terminals (Neum and Omisalj), which terminals are described, too. Slovakia is still the biggest transit state for Russian natural gas and in 2008 was signed a contract with Russian Gazprom for twenty years. If Slovakia wants to defeat this position, considered should be the links to these new pipelines or connection to the existing Yamal pipeline.  The projects to secure the gas supply for Slovakia and ensure its position in gas transit are outlined.
