Hungary vs Romania: Electricity Compared

Hungary generated 40.1 TWh of electricity in 2025 and Romania 49.8 TWh, according to Ember. Hungary's largest source was nuclear (40.1%); Romania's was hydro (24.3%). Each kWh generated emitted 162 gCO2/kWh in Hungary and 258 gCO2/kWh in Romania. These are Ember annual statistics for 2025, compiled from national sources; they are not real time.

Who is bigger and who is cleaner? Romania is the bigger electricity producer, generating 1.2 times as much as Hungary in 2025 (49.8 TWh against 40.1 TWh). Hungary has the cleaner electricity by carbon intensity, at 162 gCO2/kWh against 258 gCO2/kWh in Romania in 2025.

Why this comparison: neighbours by land border or interconnector and similar electricity demand on the same continent.
