What lies behind this number
Solar-radiation energy intercepted by the Earth system using a long-term average incoming power of roughly 173,000 TW.
How the source derives it
The source combines national energy balances, reported production, reserves and other official energy statistics.
What one number cannot show
This is a physical flux at the top of the atmosphere, not energy available to solar panels; much is reflected or absorbed.
Source value
The calculation uses the latest published daily value from NASA Earth energy budget for long-term physical average; no single reference year.
How the value is used: The running number shows the share corresponding to time since midnight.
