“…On the other hand, short-term energy security focuses on the ability of the energy system to react promptly to sudden changes in the supply–demand balance (IEA 2014). Furthermore, energy conversion and transport are also mentioned in relation to energy security as disruptions can occur anywhere in the supply chain (Jenny 2007; Scheepers et al 2007) or the ability of the system to cope with extreme events, such as hurricanes, strikes, terrorist actions and lastly, the political stability of supplying and transit countries appears in discussions (Jansen et al 2004; Le Cog and Paltseva 2009). …”

The sustainable development and energy security are currently the priority challenges for the European Union countries. The sustainable and stable development of European economies is closely dependent on the stable access to energy resources. The constant increase of the demand for electricity requires long-term planning of the common European policy. The aim of the article is to analyse the fuel and energy resources situation of the member states with regard to their energy balances and with the determination of their import dependence in relation to fossil fuels, such as: coal, oil and natural gas. Based on the collected statistical data the analysis of clusters was presented in order to separate homogenous subsets, that is groups of the European Union Member States. The squared Euclidean distance has been adopted as the measure of similarities of the member states in the clusters, and the k-means algorithm has been used as the method of grouping. As a result of the analysis seven clusters were selected-groups of homogenous countries in terms of the import dependence due to the major energy resources (oil, natural gas and coal). The results of the paper can constitute bases for shaping the appropriate long-term common energy policy for the listed potential groups of countries. Statistical data were collected based on the Eurostat publication.

“…The indicator can be criticized for neglecting two important aspects: transport risk and fungibility of suppliers (Le Coq and Paltseva, 2009). Transport risk refers to the risk of energy supply being disrupted 12 In the case of crude oil OPEC is considered as one supplier.…”

“…The net positive import share of energy consumption -referred to as net import dependency (NID) -is commonly used as an indicator for fossil primary energy import dependency. The logic behind the use of positive net-imports rather than (gross) imports is that shortfalls in energy imports can be compensated for by adjustments in energy exports (Le Coq and Paltseva, 2009). NID is calculated as the sum of the shares of positive physical net-imports for each fossil primary energy carrier in total physical primary energy supply (TPES).…”

“…7 Studies that develop and apply energy security indicators for governing energy security policies include Costantini et al (2007), Gnansounou (2008), Le Coq andPaltseva (2009), Jansen andSeebregts (2010), Lefèvre (2010), Löschel et al (2010), Cohen, Joutz, and Loungani (2011), Sovacool (2013, Frondel and Schmidt (2014), and Yao and Chang (2014). 2013; Gracceva and Zeniewski, 2014). Second, indicators are limited in assessing specific energy system's responses to exogenous future shocks as they carry only condensed proxy information (Cherp and Jewell, 2011;Gracceva and Zeniewski, 2014).…”

Terms of use: Documents in EconStor may AbstractEnergy security ranks high on the policy agenda of many countries. To improve on energy security, governments undertake regulatory measures for promoting renewable energy, increasing energy efficiency, or curbing carbon dioxide emissions. The impacts of such measures on energy security are typically monitored by means of so-called energy security indicators. In this paper, we show that the common use of wide-spread energy security indicators falls short of providing a meaningful metric.Regulatory measures to improve on energy security trigger ambiguous effects across energy security indicators. We conclude that a major pitfall of energy security indicators is the lack of a rigorous microeconomic foundation.

“…In accordance with the multi-dimensionality of the notion of energy security, numerous contributions to the literature have developed and employed quantitative measures to capture diverse resource economic aspects, with BLUM and LEGEY (2012), JANSEN and SEEBREGTS (2010), LÖSCHEL et al (2010), LEFÈVRE (2010LEFÈVRE ( , 2007, LE COQ andPALTSEVA (2009), FRONDEL andSCHMIDT (2008), SCHEEPERS et al (2006SCHEEPERS et al ( , 2007, GRUBB et al (2006), CONSTANTINI et al (2007), NEUMANN (2007, 2004), and JANSEN et al (2004 being among the most recent studies. While we find the work of JANSEN et al (2004) particularly inspiring, the present article suggests an alternative concept that is based on HERFINDAHL's (1950) concentration index, rather than SHANNON's (1948) diversity measure, thereby conceiving a risk indicator instead of a measure of supply 1 While the notion of absolute scarcity focuses on the potential exhaustion of resources such as oil or gas, relative scarcity denotes transient resource shortages, for instance due to missing supply capacities.…”
