As the capacity factor of wind is something like 30-40%, it's not "then and only then" those fossil plants will be running, it's most of the time. To reach 2C targets that's not nearly good enough.
Wind produced 37% of the country’s energy so far this year. That’s 37% not produced by coal. That it isn’t a complete solution should not be classified as a dealbreaker especially given it’s still growing and power supplies are multi-sourced anyway.
