Kevin Butt's job is to find cleaner ways to power Toyota. One of the hardest places to do that is at the automaker's sprawling plant in central Kentucky, a state where nearly 90 percent of electricity still comes from coal. A few years ago, Toyota decided that by 2050 all of its operations, all around the world, should be zero-carbon. It's part of a larger business shift. In Kentucky, General Motors, Ford, Walmart, L'Oreal and others also have big goals to reduce emissions. There's not enough renewable energy being manufactured right now for all of us to do what we say we want to do," Butt says. "The future is renewables and the large corporations that want renewables," says Jim Gardner, who used to regulate power companies as a member of Kentucky's Public Service Commission. Two years ago, Gardner was struck by an encounter with a local man who worked remotely for Facebook. He told Gardner that big corporations were actually deciding where to expand based on where they could get renewable energy. "He made it seem like there was ... a list with a lot of states with big X's marked in," says Gardner, "so that Facebook and others were not looking because [some states] were not going to be open to renewables." The Public Service Commission worried the state was missing out. It quietly issued an official statement - "a clear signal to people outside of the state," says Gardner - that if a big customer wanted renewable energy, Kentucky's utilities could cut a special deal to provide it.
