  • Grid factors are annual averages of lifecycle emissions per kWh generated (Ember / Our World in Data, latest year). They include construction and fuel supply, not just smokestack CO₂.
  • Hourly intensity can be 2–3× higher at night or in winter on fossil-heavy grids; marginal factors (what an extra kWh actually triggers) are usually higher than averages.
  • Compared: Germany 990 kg · France 123 kg · Poland 1,767 kg.
