Coming up to the Ngong Hills for field collection, I was surprised to find about a half dozen windmills up on the hill, catching the streaming winds. They were huge (in the left side of the image you can see a regular-sized vehicle for comparison), and immensely powerful. The sound that their blades made as they sliced through the air was tremendous. It was so good to see that Kenya is taking steps towards green energy, creating a sustainable future.
