How does Kendall's tau correlation relate to global solar and wind resources?

The research employs Kendall's Tau correlation as the complementarity metric between global solar and wind resources and a pair of indicators such as the solar share and a sizing coefficient usually applied in the domain of hybrid generators.

What are the implications of k-means classification of global land-based solar–wind complementarity?

Table 1. Implications for regional energy systems derived from K-means classification of global land-based solar–wind complementarity over the period 1950–2021. Ideal for hybrid solar–wind systems; leverage seasonal offsets to minimize storage needs and ensure stable energy output.

Is Kendall's tau a theoretical limit for solar-wind complementarity?

Among the primary findings of this paper, we can mention that Kendall’s Tau ranges between –0.75 and 0.75, are in line with previous research for specific regions, and might work for a theoretical limit in applied research benefiting from solar-wind complementarity.

Are solar power plants optimally distributed in South and East Asia?

We find that PV power plants are optimally distributed in South and East Asia at a latitude of 20–40°N with total power generation of 14 PWh y -1 and an average LCOE of $0.089 per kWh by accounting for the spatial distributions of solar radiation, land occupation, clouds, land cover, power demand, and capital costs (Fig. 2c).
