  1. Case studies on macro data and indicators: Training seminar on Odyssee data and indicators Madrid, IDAE, June 23-24 2010 Karine Pollier Enerdata

  2. Content • From national currency to international monetary unit (e.g. Euro or US$) • Current prices vs constant prices • Purchasing Power Parities (ppp)

  3. Currentprices vs constant pricesPurchasing Power Parities

  4. From current prices to constant prices From national currency to Euro or US£ • For comparison of energy productivity performance, economic data need to be expressed aat constant prices to remove the effect of inflation Fromcurrentprices to constant prices GDP xx (t=2005)= GDP / DEFL *DEFL (t=2005) with DEFL: GDP deflator • National currencies need to be converted in the same currency (e.g. in € in ODYSSEE) with the exchange rate of one year only for all years: the rate of the year used for constant prices (e.g. 2005) From national currency to constant € GDP €2005= GDP xx / txchg €(t=2005)

  5. Electricity intensity at constant prices (1) • GDP: from national currency in currentprices to constant € GDP €2005= GDP / DFL*DFL (2005) / txchg€ (2005)

  6. Electricity intensity at constant prices • Energyintensity trends : need to calculateintensityat constant prices • Evolution of the intensitysince 2000 (in %/year) • Electricityintensity has decresed in Sweden and Nigeria (repectively by 1.8%/y and 1.2%/y) from 2000 to 2007. • On contrary, for France the electrictyintensity has increased by 0.4%/y since 2000

  7. Changes in reference year for intensity Same trends for GDP in SEK 2000 or 2005, or in € 2000 or 2005 (+2.6%/y)

  8. Changes in reference year for intensity Sameevolution for the GDP expressed in € or PPP : PPP narrowsdifference , influence the level of the curves but does not changed the trends

  9. Electricity intensity calculation • Electricityintensity in exchange rate vs ppp exchange rate Use of PPP increases GDP and, thus, decreases energy intensity of countries with low cost of living (such Nigeria); conversely intensity of rich countries increases  (France, Sweden) PPP narrows differences between countries IE = C/(GDP / txchg) with C : electricity cons GDP in national currency txchg = exchange rate (national currency to €) Electricityintensityishigher for France in Sweden in ppp On the contrary , the electricityintensity of Nigeria is 1/3 less important in ppp compared to exchange rate

  10. Electricity intensity : at exchange rate vs ppp Narrowing of levelsat ppp
