I want to know the answer to the following question:
What does Tucson's main power plant use for fuel?
All the background I'm provided with is that "The base will soon have the largest solar-generating capacity in the United States Department of Defense after awarding a contract on September 10, 2010, to SunEdison to construct a 14.5 MW PV field on the northwestern side of the base.". Is that enough to answer the question?
Answer: no
