Within the study of energy resource management, energy intensity is a critical metric used by policymakers to evaluate national energy systems. Which of the following correctly defines energy intensity and explains its economic implication?
The total energy consumed per unit of Gross Domestic Product (GDP); a declining value indicates that a nation is generating more economic value for each unit of energy consumed.
The mass of carbon dioxide emitted per unit of electrical energy generated; a declining value indicates a successful transition to renewable technologies.
The proportion of national energy supply sourced from imported fossil fuels; a declining value indicates a reduction in domestic energy security.
The ratio of peak grid electricity demand to base-load generation capacity; a declining value indicates that the grid requires more reserve storage.
