Wood harvest energy and potential demands
| Region | Roundwood production | Harvest volume 2015 (106 m3) | Energy content of harvested wood (EJ) | Total primary energy consumption 2015 (EJ)a | Potential % of present primary energy supplied by 2015 roundwood harvests | Plausible primary wood biomass energy required by new directive (EJ)b | % of 2015 wood harvest plausibly required for expanded bioenergy in 2030c |
|---|---|---|---|---|---|---|---|
| Europe | Industrial | 333 | 3 | 70 | 4.3% | 3.9 | 130% |
| Total | 428 | 3.85 | 70 | 5.6% | 3.9 | 101% | |
| World | Industrial | 1826 | 17.9 | 571 | 2.1% | ||
| Total | 3688 | 36.1 | 571 | 4.2% |
aBased on estimate of 0.49 tDM/m3 for the World and 0.45 tDM/m3 for Europe and 20 GJ/tDM (Supplementary Methods)
bAssumes roundwood supplies 40% of mandated increase in Europe’s final renewable energy from 2015–2030, which would be mandated by RED, 35% used for bioelectricity at 25% efficiency and 65% for heat at 85% efficiency (Supplementary Note 3)
cAlso assumes Europe meets 32% target increase in European economy-wide energy efficiency from 2007 levels by 2030 (Supplementary Note 3)
