  • Estimates by VKE and mVKE are given by rows a, e, i, and l; estimates in rows b and g use long-term global mean near-surface atmospheric dissipation rates as a bound to electricity generation; estimates in rows c, d, f, g, h, j, and k use observed wind speeds and prescribed turbine characteristics without accounting for the reduction in wind speeds. A detailed description of the studies is provided in SI Appendix, Supplement D. IPCC, Intergovernmental Panel on Climate Change; Max. gen., maximum electricity generation; n/a, not derived for a specific installed capacity.
