Abstract:
The implications of various climate policies for the security of supply in the EU-25 were investigated. The security of supply was quantified using the Supply/Demand (S/D) Index. This index aggregates quantitative information on a country’s energy system into one single figure. It takes a value between 0 and 100, with higher values indicating a more secure energy system. The S/D Index was calculated for the year 2020 based on the information in a series of policy scenarios, including a baseline (S/D Index 50.7), an energy efficiency scenario (53.8), two renewable energy scenarios (52.6 and 53.3) and two scenarios with combined policies (55.9 and 55.6).The S/D Index proved a useful indicator for assessing the implications of climate policies for the security of supply. As climate policies become more stringent, CO2 index fall, and the S/D index increases. The magnitude of the changes in the two indices is not always similar however. Major falls in CO2 indices in the order of 20% for two scenarios with combined energy efficiency and renewable energy polices lead to less noteworthy improvements in the associated S/D indices. Nevertheless, this combination of policies leads to the greatest improvements in the security of supply.
