Energy & Sustainability worked example

Energy Intensity with total energy consumed in the period of 1,225,000 kWh: a worked example in energy & sustainability

Here is what the math looks like when conditions slip. We hold every other input steady and drop total energy consumed in the period to 1,225,000 kWh, then walk the calculation through step by step. Calculate energy intensity from total energy use, production volume, and conversion factor.

The inputs for this scenario

  • Total energy consumed in the period: 1,225,000 kWh (the input this scenario stresses; the baseline uses 2,450,000)
  • Production output (good units made): 610,000 units (held at the documented default)
  • Energy unit conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw energy intensity = total energy use รท production volume.
  • Reported energy intensity works out to 2.01 kWh / unit at these inputs, and this is the headline figure for the scenario.
  • Raw energy intensity works out to 2.01 kWh / unit at these inputs.
  • Energy unit conversion factor works out to 1 x at these inputs.
  • Production volume works out to 610,000 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total energy consumed in the period sits at 2,450,000 kWh and the headline result is 4.02 kWh / unit, this scenario comes in 50% below the baseline at 2.01 kWh / unit.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to total energy consumed in the period, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single representative product mix; if the units vary widely in size or complexity, a simple kWh-per-unit figure can mislead and a mass- or value-weighted denominator may be better.

Results at a glance

  • Reported energy intensity: 2.01 kWh / unit (headline result)
