How was power created on the island?

The power on the island was created using tidal turbines. This method harnesses the energy generated by the movement of tides, which can be a consistent and reliable source of renewable energy. The use of tidal turbines is especially fitting in the context of an island setting, where the surrounding ocean influences both the landscape and the available energy resources. Throughout the story, the focus on innovative and sustainable methods of obtaining energy aligns with the themes of intelligence, creativity, and problem-solving that are central to the narrative.

Other choices, like solar panels or wind turbines, while effective renewable energy sources in different contexts, are not featured as the primary means of power generation in the story. Hydroelectric generators could also be a potential choice in other scenarios but would not typically be associated with an island setting lacking significant freshwater sources needed for such systems. Thus, tidal turbines stand out as the unique and appropriate source of energy used in this specific fictional environment.
