The potatoes don't provide any energy. That's a common misconception, the energy actually comes from the two electrodes. The potato just acts as a salt bridge and ion supply. You see, when the two different metals are stuck into the potato, one of them releases positive ions into the liquid in the potato more easily than the other.
You can use this battery to power a clock for a short time for a science project or just for fun. The makeup of the potato conducts electricity, but keeps the zinc ions in the nail and the copper ions apart, forcing the electrons to move from one to the other, which generates an electrical current. You can make a potato clock using two or more potatoes.
