Documented mechanisms

Statistical

Model-supported drivers

Modeled

No active forecast for this topic records driver contributions (the champion may be a baseline with no drivers).

Candidate or hypothesized relationships

Hypotheses

  • Electricity system enables Economic output Hypothesized

    Stated, not yet evidenced here: electricity access allows productive uses (lighting, machinery, refrigeration, communications) that raise output per person. The catalog carries both series; no causal study is attached.

  • Electricity system enables Human health and longevity Hypothesized

    Stated, not yet evidenced here: electricity access allows refrigeration of vaccines and food, lighting in clinics, water pumping and a shift away from solid cooking fuels, all of which bear on mortality. The catalog carries both series; no study is attached.

Not settled by stored data

Unknowns

  • Data-center load growth is announced, not metered; the stored series cannot separate it from other demand.
  • Interconnection queue withdrawal rates are not ingested, so the share of the planned pipeline that completes is not known from stored data.

Solid: observed (million kilowatthours). Dashed and shaded: model point estimates and 80 percent intervals from empirical residual quantiles. Filled dot: the record on this page. Green or red dot: the realised value, inside or outside its interval.

Base case

360,015.28 million kilowatthours

The point estimate: the model's central path.

Upside

374,291.78 million kilowatthours

Upper bound of the interval: what would need to go better than the central path.

Downside

350,484.28 million kilowatthours

Lower bound of the interval: what would need to go worse than the central path.

The model assigns 80 percent to the interval; the site assigns no other probability.

Falsifiers and assumptions
  • If the first published value of us-electricity-net-generation (USA) for 2027-05 is below 350,484 million kilowatthours or above 374,292 million kilowatthours, the 80 percent interval is falsified.
  • The model assigns a 10 percent probability to a value below 350,484 million kilowatthours and a 10 percent probability to a value above 374,292 million kilowatthours; interval misses should occur about one time in five over many forecasts, and a run of misses well above that rate falsifies the calibration.
  • The point forecast is above the last observed value (354,691 million kilowatthours); a realised value at or below that level falsifies the direction call.
  • Assumption: No structural break in us-electricity-net-generation between the data cutoff and the target period.
  • Assumption: The source keeps publishing the series on the same definition; a rebasing or redefinition invalidates the comparison.
  • Assumption: The average historical change per period continues.
