Energy Transition
How has the US renewable share of final energy changed?

Try it in 60 seconds
- Read the question. Check the source response and retrieval time before trusting any reading.
- Drag across the plot to inspect a value.
- Tap either reading card to reveal what it means. Open Explore for another view and the source records.
- Find the observation time. Total final energy is not the electricity mix. Missing years are omitted, never interpolated or replaced with zero.
The idea worth keeping
Annual observations need an explicit year. A freshly fetched number can still describe the past.
A short script you can read aloud
“How has the US renewable share of final energy changed? This layout starts with that question, not a wall of controls. The data comes from World Bank WDI / International Energy Agency. Drag across the plot to inspect a value. The reading cards tell you what to notice; turn one over when you need context. Annual observations need an explicit year. A freshly fetched number can still describe the past. One important limit: Total final energy is not the electricity mix. Missing years are omitted, never interpolated or replaced with zero.”
Suggested animation scene
Trace the series with a single moving dot. Reveal its unit, then its observation time. Never animate a missing reading into a zero.
Storyboard: 0–8 seconds, ask the question. 8–25 seconds, introduce one observation. 25–45 seconds, perform the gesture above. 45–60 seconds, show the timestamp and limitation. Keep labels readable, offer a reduced-motion cut, and use actual source values or a clearly marked replay.
How this becomes a layout
The provider publishes data → a small read-only adapter selects and names the useful fields → CAR-TER controls bind to those fields. All controls in this template share one endpoint. Polling is cached for 86400 seconds; that is a retrieval interval, not a promise that the source updates that often.
Remix exercise
Duplicate this layout. Keep the source and units unchanged, but replace the primary visualization with the alternative in Explore, or move the record list above it. Ask a new reader which arrangement answers the opening question faster. Changing location or query parameters requires a new allowlisted server-side source, not an unwired selector.

This is a selected result window, not a full archive. Missing numbers are not replaced with zero. Lines connect available observations; consult records for gaps. A green READY badge means the last retrieval succeeded, not that the underlying observation is recent. STALE means a retained prior response; UNAVAILABLE means no usable cached response. If your device goes offline, check the displayed retrieval time: the last screen can remain visible.
Open-data and publicly accessible API are different promises. This collection labels each source’s conditions; it does not assert that every provider’s database or API is open-source software.
