Thank you

wind_2018 %>% 
mutate(germany = ifelse(country_name=="Germany", "True", "False"),
    country_name = fct_recode(country_name, "<span style='color:firebrick'>Germany</i>" = "Germany"))%>%
  ggplot(aes(x = gigawatts, y = country_name)) +
  geom_col(fill=germany, alpha = .9, show.legend = FALSE) +
  scale_fill_manual(values = c("steelblue", "firebrick")) + 
  scale_x_continuous(labels = scales::comma) +

wind_2018

Can you provide a reproducible example of wind_2018? What does that look like? From the error message it looks like it is already a plot when you read it in.

Therefore wind2018 is a plot and not a dataframe so mutate wont work. You can rearrange things and mutate earlier before constructing a plot.
