Descrição: Energy is essential for human needs satisfaction. With the evolution of machinery, man becomes more and more dependent on the energy stocked in fossil fuels, comparatively to the primitive economy. Wood charcoal is a thermal reducer used in Brazilian pig iron and steel industries, and its price is formed in an oligopsonic market. Over time, the charcoal prices have varied in function of endogenous and exogenous factors, needing, therefore, to be deflated so that they can be compared in two or more points in time. This work analyzed the variations of charcoal real prices, in national currency; compared and analyzed the real charcoal price in nominal and in real US Dollar and; analyzed the real prices of charcoal, comparatively to the real oil prices. The analyses were accomplished in the period from January 1975 to December 2002. The time series of charcoal prices, in domestic currency were deflated using IGP DI, considering august, 1994=100, and charcoal prices were also converted to American dollar and deflated using CPI, considering the period 1982-84=100. It was compared, then, the real and nominal charcoal prices. It concluded that the real charcoal prices in Brazilian domestic currency, or in American dollar, presented a decreasing tendency along time. The inflationary disarray, in the 80´s and the first half of the 90 ´s, provoked a big price variation in the period; from the beginning the XXI century, charcoal prices were more influenced by the exchange rate; in the energy crisis period, charcoal prices suffered big changes that, however, did not persist along time.
