Energy security
Reliable, affordable access to all fuels and energy sources
The IEA was created to ensure secure and affordable energy supplies, and it conducts analysis on current and future risks for oil supply disruption, emerging gas security challenges, and increasing system flexibility and resilience of the electricity sector. But energy transitions and the growth of cyber criminality have expanded the scope of what constitutes energy security.

Our work on energy security
The IEA defines energy security as the uninterrupted availability of energy sources at an affordable price. Energy security has many aspects: long-term energy security mainly deals with timely investments to supply energy in line with economic developments and environmental needs. 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.
