Question

which type of energy turns tidal turbines to create electrical energy?
kinetic
potential
solar
thermal

Explanation:

Kinetic energy is the energy of motion. Tidal turbines are turned by the movement (motion) of water (tides). Potential energy is stored energy (not related here as no storage - release of energy in the sense of turning turbines). Solar energy comes from the sun (not relevant to tides). Thermal energy is related to heat (not relevant here). So, the energy of moving water (kinetic) turns tidal turbines.

Answer:

kinetic
