    • What are the key components of energy security?
      • Availability: uninterrupted energy supply
      • Accessibility: energy must be reachable
      • Affordability: competitively priced energy
      • Reliability: uninterrupted energy supply
    • Why is energy security important for a country?
      Energy is vital for the functioning of a country, powering transport, lighting settlements, and more.
    • How is energy consumption measured?
      In per capita terms, as kilogrammes of oil equivalent or megawatt hours per person.
