 To accurately model the temporal and spatial availability of renewables such as wind and solar energy, we rely on historical weather data.
 It is advisable to adapt the required range of coordinates to the selection of countries.

+   :start-at: atlite:

 We can also decide which weather data source should be used to calculate potentials and capacity factor time-series for each carrier.
 For example, we may want to use the ERA-5 dataset for solar and not the default SARAH-2 dataset.

 Finally, it is possible to pick a solver. For instance, this tutorial uses the open-source solvers CBC and Ipopt and does not rely
 on the commercial solvers Gurobi or CPLEX (for which free academic licenses are available).
