19% is nothing to sneeze at.
We’re not even close to that in the US, and probably never will be.
I don’t support wind over more efficient sources, but for some remote applications, 19% would be a hell of a start.
The entire country of Denmark is about the size of New Hampshire. The power those turbines produce has very short distances to travel. The nature of the off shore location of the turbines also sees a more active wind pattern than what the central USA is even remotely capable of.
Just the distances we have to move that power here in the US make it ridiculous. Even with those facts and prohibitive issues against this, they are still building wind farms all across the Midwest. We cannot possibly see anything more than 2 or 3% of our electrical needs being met by Wind power, even under the most ideal conditions. The vast amounts of distance and unstable weather patterns here, make the result seen in Denmark virtually impossible.
