There is some apparent confusion in the units of this article, and some of the values are apparently confused as well. Confusion between the terms "annual production" and "generating capacity" apparently aggravate the issue. Generating capacity refers to the maximum instantaneous flow of power that is capable of being produced, measured in watts, or in this case, megawatts (MW). Electrical production, on the other hand, is measured in watt-hours (W-h) or gigawatt-hours (GW-h), and represents the average flow of power times the number of hours the power flowed. If a generator has a generating capacity of 1 watt (1 W), then if that generator runs for an entire year at full capacity, then it's annual production would be (365 days * 24 hours * 1 watt = ) 8,760 W-h, or 8.76 kW-h. Apparently the term "generating capacity" has been conflated with annual production, while correctly using watts instead of watt-hours. However, if the data are correct, then that would mean that China has well over 600 times (!!!) the wind generating capacity of the United States (25 GW versus 40 MW), contradicting the claim in the general wind farm article that China ranks third behind the United States and Germany in wind generating capacity. More likely, where GW are listed for "generating capacity," GW-hours and "annual production" should be substituted, unless some reliable authority can be cited to show that China has over 200 times the wind generating capacity as the rest of the world combined.
