If Poland were to burn all its forests, it would produce enough energy to meet Poland's demand for not even 10 months. Calculations by Piotr Podsiadły.
2 tons of green wood produces 1 MW/hour [source]
80 tons of green wood is produced per acre [source]
The average Polish citizen uses 80 kWh every day (including heating, transportation and electricity) [source]
38 million * 80 kWh = 3,040 GWh daily, giving 1,109,600 GWh annually.
Annual electricity generation in 2018 was 170,039 GWh [source] so that cross checks with the value above.
To support this annual energy consumption Poland would need to burn 2*1,109,600*1000 = 2,219,200,000 tons of green wood, which would require cutting 2,219,200,000/80 = 27,740,000 acres of forest.
There are 9,2 million hectares of forest in Poland [source].
1 ha = 2.47105 acre.
27,740,000/2.47105/1,000,000 = 11.2 million hectares of forest to meet the current annual energy demands.
9.2/11.2*12 months = 9.9 months
If we burn all forests in Poland, we would produce enough energy to meet Poland’s demand for only about 10 months.
Polish old forests would need at least 60 - 80 years to regrow. We don't have enough land to sustain such energy production.
