Electricity use and low-carbon share by year

Electricity figures are scattered through sustainability reports in different units, under different headings, and often as a percentage with no total. Comparing two suppliers means reading both reports.

The Energy tab does the reading. Consumption is standardised to megawatt hours for each reporting year, with total, low-carbon and non-low-carbon electricity in a table beneath the chart and the year-on-year change beside each value. Switch the table between a low-carbon view and a renewable view.

Hover any value to see whether it was disclosed in the document, derived from other disclosed figures, or assumed. Click it and the source document opens at the page the figure was taken from, which is the check a category manager or an auditor will want to make.

The chart carries the regional grid's low-carbon share as a line across the same years, so the organisation's direction reads against the grid it operates on. The tab sits alongside the organisation's emissions, targets and source documents.
