According to the EIA [0], wind energy reached 5.6% of total electricity production. Having worked with raw EIA data I can say that the inputs are not very reliable: a) a lot of smaller farms are not included in EIA data b) reporting is voluntary and 30%+ of wind sites stopped reporting data in 2016, for example [1], and c) reporting is based on surveys which means errors, delays, etc. The US is really lagging behind…
As someone who is working with global powerplant data I can say that the US is the global leader. It is not perfect, but it is miles ahead of 170 other countries.
The UK has a live feed of the makeup of the power plants that is updated on this website every 15 minutes.
