Gas is competing with oil for being the dominant energy source. In electricity generation gas is to play as pivotal a role as oil in transportation. The security equation of gas and electricity become unseparably interrelated. Energy disruptions have considerable influence on the national accounts far beyond the direct cost of market participants (asymmetry). The present gas supply to the EU depends dangerously on too few sources and venues. There is a decided lack of optionality. The EU directly or through its members needs a clear proactive policy on "Security of Gas Supply" with a strong multilateral direction. The measures developed for the oil industry over the last 30 years can at least serve as a starting point for a constructive debate. When discussing security of supply dependence it is useful to clearly define the various risks one wishes to protect against. Free riders relying on alternative fuels without participating in their security systems are not permissible. (c) 2005 Elsevier Ltd. All rights reserved.
