Sorry the chart is so small, it was all I could find on short notice, but this is a chart of the 'average' monthly output of a wind turbine. I guess I was wrong, June is the 'slowest' month, but note the dip in the summer months, when the usage is the highest.
The chart above is from a Germany grid study and is found here. It is 12 days of data with the red being the maximum 15 minute wind input to the grid and the green being the minimum for that 15 minute. Look at the enormous fluctuations. This is an enormous grid in Germany and represents THOUSANDS of turbines spread across the country. Keep in mind, this is for the entire grid of mills, not just one turbine. IMO, until we get some way to store the 'spikes' for use during the 'lags' wind power will at best be a supplement to other forms of generation.
As far as where they are made, a trucker showed me, on the gearbox of one of them, where it said 'China'. He tells me, for the farms he has hauled them to, they are either Chinese, or Swiss, because the particular size of the mills that get the biggest subsidy, were not made in the USA (at least not at the time we spoke).
The mills go through town pretty regularly, and can only carry the BIG parts during daylight, and with a chase car with flashing lights, so they overnight from time to time. One place you can see them doing this fairly often is the Bosselman Truck Plaza near Grand Island, NE, where they exit I-80, and turn North. I've even seen them overnight in small towns like Burwell, NE. The trucker there told me small towns were often the easiest to stop at, as they often have a place to park an oversized truck, not too far from a motel. If you ever see one stop, chat with the driver. The few I have seen, seem willing to chat, and almost appreciate the company of someone other than the chase car driver, or the 'Jeep' driver (from what I can tell, that is the steerable rig on the back of some of those very oversized trailers that helps them take corners better).
