Arizona still gets a significant amount of power from burning coal. How soon could that change?
Four years ago, the biggest electric company in Arizona declared that solar energy plants paired with batteries were the cheapest way to power the state, marking a major departure from fossil fuels. Months later, the largest coal-fired power plant in the West, the Navajo Generating Station, shut down outside of Page, ending a 45-year run. Arizona Public Service Co. and Salt River Project appeared to dive headfirst into renewables at the expense of coal.
