Total energy intensity 1995-2004 (1995=100) and total energy intensity in 2004 relative to EU-25 (EU-25=100)
The last column shows the energy intensity measured in purchasing power standards relative to the EU-25. These are currency conversion rates that both convert to a common currency and equalise the purchasing power of different currencies. They eliminate the differences in price levels between countries, allowing meaningful volume comparisons of GDP. They are an optimal unit for benchmarking country performance in a particular year.
