Security of supply is not a single variable

When renewable activists talk about wind energy's contribution to Security of Supply, electrical engineers don't know what they're talking about. The background is that Security of Supply has many facets, and means very different things to different people. A Eurelectric report contributes to the understanding of the issue, breaking it down in following variables:
  • Long-term
    • Access to primary fuels
    • System adequacy (Generation adequacy + Network adequacy)
    • Market adequacy
  • Short-term: Operation Security
Wind power, for example, improves 'access to primary fuels', but performs less on other aspects. Gas-fired power stations, on the other hand, do not improve security of fuel supply, but supports well the other aspects of supply security.
