“…The politicisation of the Russian natural gas exports to Europe and the shift from an economic interdependence to a political risk took place only recently, in the last decade, and occurred in the context of the EU's enlargement in 2004 and 2007 (Nies, 2011) and of the gas transit disputes with Ukraine (Terterov, 2010; see Sharples, 2013Sharples, ), in 2006Sharples, , 2009Sharples, and 2014 As such, energy security mainly focuses on the security of supply and on the affordable prices for the consumers, citizens and businesses, having "access to sufficient energy resources at reasonable prices for the foreseeable future free from serious risk of major disruption of service" (Barton et al, 2004: 5, see Winrow, 2007). Conceptualisation of energy security as a consumer-centric concept (Sharples, 2013), focused on the security of supply, has been feeding the theoretical fields of both political realism, concerned with the conflictual aspects of energy relations, as well as of neoliberalism/neoclassical economics, focused on the cooperative potential of energy relations at legal, economic and institutional level (Stoddard, 2013).…”
