The energy production from phytomass on agricultural and forest lands can be calculated on the basis of the annual production of hydrocarbons (cellulose, starch, sugar, etc.), without needing to take into account the type of phytomass and the mean-weighted specific power production per unit of land area. Land with a mostly uniform climate and soil class produces similar specific power per unit of land area. It was proved in the case of the Czech Republic, where the meanweighted value of specific power production has been calculated as 3.16 kW/ha. Biomass energy can be released in three ways in which conversion takes place. i) direct phytomass combustion, ii) conversion to methane (biogas), iii) conversion to bioethanol. Conclusions about the effectiveness of different conversion methods were obtained by executing the enthalpy balances of the individual transfer processes. The method using methane (raw gas) seems to be the most energetically advantageous. The close connection between the circulation of CO₂, H₂O, and O₂ has been quantified. The same amount of water as CO₂ is produced and remains int in the atmosphere, and it significantly reflects radiation away from the ground. Cooling heat flux can be lowered about 1.6 times, thus contributing to climate change.

农业和林地植物群的能量生产可以根据碳氢化合物（纤维素、淀粉、糖等）的年产量计算，无需考虑植物群的类型和平均加权比功率单位土地面积产量。具有基本一致的气候和土壤等级的土地每单位土地面积产生相似的比功率。这在捷克共和国的案例中得到了证明，其中单位发电量的加权平均值计算为 3.16 千瓦/公顷。生物质能可以通过三种方式释放，其中发生转化。i) 直接植物体燃烧，ii) 转化为甲烷（沼气），iii) 转化为生物乙醇。通过执行各个转移过程的焓平衡，可以得出关于不同转化方法有效性的结论。使用甲烷（原料气）的方法似乎在能量上是最有利的。CO循环之间的紧密联系₂、H ₂ O 和O ₂已被量化。产生与CO ₂相同数量的水并保持在大气中，并且它显着地将辐射反射离开地面。冷却热通量可降低约 1.6 倍，从而导致气候变化。
