Correction to: Nature Energy https://doi.org/10.1038/s41560-019-0326-1, published online 25 February 2019.

In the version of this Article originally published, the units for ‘Electricity price, pe’ and ‘Subsidy: PP or PTC’ in Table 1 and ‘LCOE’, ‘Levelized PP’, ‘Levelized PTC’, ‘Wind energy profit margin’, ‘Conversion premium’ and ‘LFCH’ in Table 2 were incorrectly given as ‘€ kWh–1’ for Germany and ‘US$ kWh–1’ for Texas; these should have read ‘€c kWh–1’ and ‘US$c kWh–1’, respectively. In Fig. 1, the y axes labels were incorrectly given as ‘€ kWh–1’ for panel a (Germany) and ‘US$ kWh–1’ for panel b (Texas); these should have read ‘€c kWh–1’ and ‘US$c kWh–1’, respectively. These errors have now been corrected.
