(1) KNU Definition
This KNU represents the speed at which renewable energy may grow in the future. It is represented as a time function, that is, with a few estimates for different points in the future.
Renewable energy deployment has grown considerably in the past 20 years, as it became more affordable. Chine, in particular, has contributed to this spectacular growth.
Yet it becomes difficult to forecast at the worldwide level, because deployment is a bottleneck (especially for solar pannels) and because the will to deploy renewable intermittent sources varies from one country to another.
(2) What the slider in G2WS does ?
The slider allows to change the default hypothesis, expressed in PWh/year, for different moments in the future (2030, 2050 and 2100).
The control KPI is ...

Renewable Growth
The illustration on the left shows the recent history of renewable (wind + solar) deployment in the world. Note both the deployed power in GW which is impressive (and often quoted) and the actual production in TWh (which factors the loading rate that is less impressive for intermittent sources of energy)
