Electricity production is the electrical energy generated by the potential energy of water
J＝mgh*efficiency=mgh*n=ρVg*H*n=1*1000* 365*24*60*60 *Q* 10*H*n＝3.1536*10^11(J)=8.76*10^10(degree)
A. Tidal energy is the energy contained in seawater when the ocean rises and falls regularly. tides are used. To produce electricity for human use, it can be inexhaustible like wind power, so the statement is correct and does not fit the meaning of the question;
B. is to increase the gravitational potential energy of the water, so that the water can be converted into more kinetic energy as it flows, which is used to drive the turbine to produce electricity at the instead of increasing internal energy. Therefore, the statement is false and consistent with the. meaning of the question;
C. Modern large-scale hydraulic turbines not only have power, but theyes are large and efficient, which is consistent with the actual situation, so the statement is correct and does not correspond to the meaning. of the question.
Then choose B.
