Yes I researched those—and I think if I started out on day one and said, “I’m going to do a book and look for all these places,” it would’ve taken forever. The fact that this project was built on my blog and my Instagram feed structure, with one a day, enabled it to build on itself. It was driven by my interest in environmental issues. The way I went about finding the images was with an idea first and then a search to find it. For example, for one of the solar concentrators, the research process would be, “I’m looking for energy; I’m looking for a solar panel facility; I’ll find a list of the largest solar panel facilities in the world.” A resource like Wikipedia is indispensable for a project like this where they’ll give you a list of the largest solar panel facilities, nuclear power plants, you name it, with geo-coordinates next to them.
