Estimates of wind power potential are relevant for decision-making in energy policy and business. Such estimates are affected by several uncertain assumptions, most significantly related to wind turbine technology and land use. Here, we calculate the technical and economic onshore wind power potentials with the aim to evaluate the impact of such assumptions using the case-study area of Finland as an example. We show that the assumptions regarding turbine technology and land use policy are highly significant for the potential estimate. Modern turbines with lower specific ratings and greater hub heights improve the wind power potential considerably, even though it was assumed that the larger rotors decrease the installation density and increase the turbine investment costs. New technology also decreases the impact of strict land use policies. Uncertainty in estimating the cost of wind power technology limits the accuracy of assessing economic wind power potential.

风能潜力的估算与能源政策和商业决策相关。此类估计数受若干不确定假设的影响，这些假设与风力涡轮机技术和土地使用最相关。在此，我们以芬兰的案例研究区域为例，计算技术和经济上的陆上风力发电潜力，以评估这些假设的影响。我们表明，有关涡轮机技术和土地使用政策的假设对于潜在估计而言具有重要意义。尽管假定较大的转子会降低安装密度并增加涡轮机投资成本，但具有较低比额定值和较高轮毂高度的现代涡轮机可显着提高风力发电潜力。新技术还减少了严格的土地使用政策的影响。
