Threats to a nation's energy security include:[4]

  • Manipulation of energy supplies (e.g. mega-corporation or state-backed racketeering)
  • Competition over energy sources (e.g. biofuel (biodiesel, bioethanol) vs oil (crude, distilled fuel) vs coal vs natural gas vs nuclear vs wind vs solar vs hydro (dam, pumped))[citation needed]
  • Unreliable energy stores (e.g. long time to spin a turbine to create power, or Li-ion battery grid explosion, or pumped hydro dam becoming clogged)
