Measuring Software Carbon Footprint and Energy Efficiency

A key part of Green Testing is measuring the energy consumption and environmental impact of software workloads.

Understanding Energy Consumption

Energy consumption represents the amount of electricity used by computing equipment and software workloads over a given period. It can be measured in watt-hours or kilowatt-hours, depending on the measurement system.

For example, teams may compare energy use during different test scenarios to identify workloads that require excessive resources.

Understanding Carbon Footprint

A software application’s estimated carbon footprint depends on factors such as energy consumption, electricity generation sources, infrastructure efficiency, and workload distribution.

A simplified estimation approach is:

Estimated carbon emissions = Energy consumed × Carbon intensity of electricity

For example, if a workload consumes 10 kWh of electricity and the applicable electricity carbon intensity is 0.7 kg CO₂e per kWh, the estimated emissions would be 7 kg CO₂e.

This is an illustrative calculation. Actual estimates require appropriate measurement boundaries, location-specific electricity factors, and consideration of infrastructure overhead where relevant.
