1. From the mass consumption, calc the volumetric consumption by fuel by country
2. Calculate the weighted average price for all countries:
Multiply the price by the consumption
Summate for all countries
Divide total by the total consumption (where prices are non-zero)
3. For the real prices, divide each price by the appropriate HICP (2005 = 1) and repeat 2
4. 'Gasoline' equivalent price is obtained by:
Multiply the fuel price by the consumption and divde by its energy relative to unleaded petrol
Summate for the three fuels and divide by the total consumption
