Expressed in the purchasing power standard (PPS), an artificial common reference currency that eliminates general price level differences between countries, it can be seen that, relative to the cost of other goods and services, the lowest household electricity prices were found in Finland (12.8 PPS per 100 kilowatt-hours), Luxembourg (13.5 PPS) and the Netherlands (14.2 PPS), while the highest were recorded in Germany (28.7 PPS), Portugal (28.6) and Poland (25.9).

Adjusted for purchasing power, it can be seen that, relative to the cost of other goods and services, the lowest household gas price was recorded in Luxembourg (3.5 PPS per 100 kilowatt-hours), ahead of the U.K. (4.3 PPS) and Belgium (4.7 PPS), while the highest prices were observed in Portugal (9.7 PPS), Sweden (9.5 PPS) and the Czech Republic (8.4 PPS).
