Energy intensity is best described as:

Energy intensity is best described as:

• A. Energy use per unit of output
• B. Total energy consumption
• C. Energy cost per unit
• D. Energy efficiency ratio

Answer: (A)

Energy intensity measures how much energy is used to produce a unit of output. It’s a way to gauge how efficiently energy is used in production or an economy, typically calculated as energy consumption divided by output (for example, energy per GDP or per ton of product). If output rises faster than energy use, energy intensity declines, signaling improved efficiency or a shift to less energy-intensive activities. It’s not just total energy use, which doesn’t account for how much is produced, nor is it the energy cost per unit or a vague “energy efficiency ratio.” So the best description is energy use per unit of output.
