How much electricity can wind power produce in a day? Your question is too general to answer.
But I can give you a rough estimate: the current average effective power generation time of wind power generation devices in a year is about 2,000 hours, which means that the average power generation time is 5.48 hours per day. By multiplying 5.48 hours by the installed capacity of a certain wind turbine, you can easily calculate the average power generation of this generator in a day. For example, a standard 3MW wind turbine generates an average of 16,440 kilowatt-hours (Kwh) of electricity every day.
