The several most common ways to generate electricity were hydroelectric, wind power, thermal power, solar power, and nuclear power.
Gu Nianzhi quickly recalled the physics knowledge she had learned from the expert instructors at the Special Operations Forces, and combining it with the surrounding situation of the water around the blue hole, she immediately eliminated the possibilities of thermal power and hydroelectricity.
Hydroelectricity required an extreme flow of water or a large temperature difference in the seawater in order to generate electricity. However, the current geography and water conditions obviously didn't fulfill the requirements for hydroelectricity.
Also, hydroelectricity required large scale infrastructure.
The blue hole's surroundings had no trace of human influence because its most natural topography had been preserved, so this completely eliminated the possibility of hydroelectric generation.
