According to some studies, the use of forest biomass for the generation of electric power and/or heat would result in a significant reduction in the emission of greenhouse gases. This would happen even in the case of soils substitution that currently have an agricultural use although its implementation would require more studies on the environmental impact that they could have in each particular case. In this study, the potential of electric power production is evaluated with several species of Eucalyptus planted in short rotation forestry systems. Three species were evaluated: E. benthamii, E. dunnii and E. grandis in four spacings: 3×1.5 m, 3×1 m, 3×0.75 m, 3×0.5 m, in two sites in the northern and western areas of Uruguay during a period of 76 and 75 months, respectively. During this period, the following parameters were evaluated: higher heating value, wood density, energy density and energy yield per hectare and per year. The results obtained show that the heating value changes slightly with the planting density and age. The average of higher heating values were 19,787 versus 19,454 J g-1 and 19,867 versus 9909 J g-1for the planting densities of 2220 versus 6660 trees ha-1 at Paysandú and Tacuarembó, respectively, at 76 months. Higher heating value increased from 19,665 to 19,745 J g-1 at 18 months to 19,740 and 19,914 J g-1 at 76 months for Paysandú and Tacuarembó, respectively. The wood density, depending on the site, is affected by age, species and planting density. On average, wood density increased (only at Paysandú) from 0.405 g cm-3 at age 18 months to 0.497 g cm-3 at age 76 months. There is a negative relationship between the heating value and the wood density. The energy yield is basically explained by the production of biomass. At Tacuarembó, a stronger relationship between energy production and planting density is obtained (1012 vs. 636 MW ha-1 for 6660 and 2220 trees ha-1, respectively) compared to the Paysandú site (1093 vs. 912 MW ha-1 for 6660 and 2220 trees ha-1, respectively). Harvest times are different in each site depending on the IMA values obtained.

Short-rotation plantations have been suggested to develop renewable energies in South America. Our study evaluated the biomass production of Eucalyptus benthamii, E. dunnii and E. grandis plantations at stocking densities of 2220, 3330, 4440 and 6660 trees ha-1 in the North (Tacuarembó) and West (Paysandú) of Uruguay,
over a 76-month period. The species survival was not related to planting density, and the highest mortality rates occurred at Tacuarembó. The effects of tree competition were more evident for E. grandis. At Tacuarembó site, the average survival of the species were: 57, 57 and 46% at age 76 months for E. benthamii, E. dunnii and E. grandis, respectively. Survival rates were similar for the different planting densities, with ranges between 50 and 57%. At Paysandú site, the average survival of the species were: 83, 86 and 75% for E. benthamii, E. dunnii and E. grandis, respectively, with a range from 78 to 84% for different planting densities. Weather conditions (temperature and rainfall) were similar at both sites throughout the evaluation period. Wood density and individual and total biomass weight (kg tree-1 and Mg ha-1,respectively) were evaluated sampling destructively 2592 trees and logarithmic biomass equations were developed using the diameter at breast height (cm) and total height (m) of the trees. Wood density increased with the age of the crop only at Paysandú. On average, wood density increased from 0.405 g cm -3 at age 18 months to 0.497 g cm -3 at age 76 months. The highest wood density was observed at 76 months on E. benthamii (0.413 and 0.431 g cm -3) and E. dunnii (0.496 and 0.539 g cm -3) at Tacuarembó and Paysandú, respectively. Age had no effect on the wood density at Tacuarembó. The stem biomass showed an inversely-proportional relationship with the planting density. Individual stem biomass was higher for E. grandis (81 and 74 kg tree -1 on average at Tacuarembó and Paysandú, respectively) than for the other species. The highest biomass per hectare was achieved for the highest planting density, specifically for E. dunnii (193 Mg ha -1) and E. grandis (203 Mg ha -1) at Paysandú and for E. dunnii (157 Mg ha -1) at Tacuarembó.
