Why Energy Charts Are Read as Arguments
Energy charts are never read neutrally. A curve showing capacity growth is taken as a claim about how fast a transition is happening, and the same curve plotted against total demand instead of against last year reads as the opposite. The axis choice is the argument, whether or not it was meant as one.
A communications team that does not decide this deliberately will have it decided for them by whoever screenshots the chart. The honest approach is to make the framing explicit in the scene rather than to pretend a chart can be presented without one. What stays out of the published version is forward projections presented as data: scenarios, targets, and modelled pathways are assumptions and must be visually distinguished from measured history.
The template plots it across six scenes: one on what is being measured and against what, two on capacity growth by technology, one on cost per unit over time, one on the constraint that capacity alone does not address, and one on where the underlying dataset sits.
