This dimension groups energy milestones by the year in which they occurred. Wikipedia notes that "from 2011 to 2021, renewable energy grew from 20% to 28% of the global electricity supply," a decade of milestones each dated to its own specific year. Browsing by milestone year lets a visitor compare milestones that happened at the same time.
