Which of these is anl advantage of hydropower

B. It has high power plant efficiency.

Explanation:

Hydropower is the renewable energy source that converts the potential energy of stored water into the kinetic energy of flowing water and uses the same to generate electricity. Since water stored at height has ample of potential energy, hydropower plants are highly efficient in generating the power.It has many disadvantages such as harmful effects on aquatic organisms by construction of dams and high cost of plant constriction.

the answer is tropical areas. the tropical areas obtain more
