Actually, you don't really need that many. I'll have to see if I can find the article that talks about it.

@BeeHappy oh I'm very curious

Would kill birds, tho. How many I'm not sure, & would have to be very careful in flyways!

@MrLink and @phxbillcee guys, they made a lot of progress with wind. There are more options than just the large wind turbines.

This is as of Sept 2016 and is based on the typical wind turbine:

But what would a US powered only by wind actually look like?
To answer that question, AWEA's manager of industry data analysis, John Hensley, did the following math: 4.082 billion megawatt-hours (the average annual US electricity consumption) divided by 7,008 megawatt-hours of annual wind energy production per wind turbine equals approximately 583,000 onshore turbines.

In terms of land use, those 583,000 turbines would take up about the total land mass of Rhode Island, Hensley says, because wind projects typically require 0.74 acres of land per megawatt produced.

Sorta yes, but not exactly...
