"This is a major contribution to the Netherlands’ goal of 16% sustainable energy in 2023, states the Dutch government."

The part that I don't quite get is that despite these major developments, we're still talking projected sustainable energy percentages (both in this article and the Texas one before this) in the teens. I hope they are making the classical mistake of not taking into account the rapid economies of scale and technological improvement. Because we need to do a lot better than that over the next couple decades.
