Just a little correction. A large wind turbine can generate 4MW,or 100,000 kWh per day. So it would take 7 large wind turbines running at full capacity round the clock. But it would require an equal capacity gas-powered plant to back it up.
If that gas powered plant were to be shut down via govt. fiat, then what would be the required number of wind turbines to provide 650,000 KWH per day?
