With Earth Day arriving in a couple of days, we're chatting on this edition of StudioTulsa about the plan that Public Service of Oklahoma (or AEP/PSO) now has to effectively flip its power-generation sources. That is, to flip from from 70 percent carbon sources and 30 percent renewables, as the equation stands today, to 70 renewable sources and 30 percent natural gas (with zero coal sources), which AEP/PSO says that it's on track to achieve by 2031. Our guest is Scott Ritz, director of customer service and marketing at Public Service of Oklahoma.
