Task · part of 6. Five pie charts, and where the numbers came from
6(e). The world's known and estimated primary energy reserves
Required
The only one of the five that is global rather than national, and the only one resting on estimates.
Notes and warnings
Note. The only global chart of the five, and the only one built on estimates rather than measurements. Reserves figures differ between sources and get revised, so this is the chart where naming your source matters most.
