Solar share of demand
Solar as a share of demand
1.9D % of demand
Cohort (markets reporting both demand and solar): Denmark, Taiwan · 2 of 11 markets
solar 0.7 GW ÷ demand 34.7 GW
Computed only over the markets listed: solar generation of those markets divided by their demand, at the same timestamp window. Other cards cover different market sets and are not comparable.
CO2 (derived)
CO2 now (derived from generation)
17366D t CO2eq/h
Included markets: Great Britain, Taiwan · 2 of 10 markets
Derived: metered generation × published factor (IPCC AR5 WGIII Annex III lifecycle medians — table v1, 2026-10-23).
Oil 650 g/kWh (proxy; AR5 gives no oil median).
Not counted: 2357 MW of unknown-fuel generation in the included markets.
Denmark excluded: thermal output is not split by fuel.
