CEVAP:

Energy security can be further studied from three perspectives: the security of the energy supply, the energy demand security, and the energy transfer safety. The security of the energy supply refers to the reasonable supply of the
energy resources to countries until these resources are exhausted. The energy demand security ensures that energy-suppliers sell their resources at the highest price possible in the most suitable markets. The energy transfer safety involves the majority of the risks and threats associated with the energy security today.
