1. Hydropower and small hydropower plants

​

Advantages:

                     The biggest advantage of hydropower and small hydropower plants is that they are environmentally

                     friendly renewable energy. Hydropower generates electricity by using water, so it does not discharge

                     any fuel and does not emit air pollutants. You can reduce carbon dioxide, a major cause of global warming.

​

Disadvantages:

                      1. Significant funding for dam construction requires investment,
                       (Eg, immigration problems in the submerged area, conflict resolution with people in the downstream area, etc.)

                      2. Environmental problems

                          (ecological problems such as blockage of transportation routes and change of residential environment to

                            animals due to environmental changes,)

                      3. It is a reality that only places that do not have the economic value of hydroelectric power plants remain.
                          (A problem that the investment cost of the power transmission and distribution increases when the distance

                           between the power plant and the electricity supply is long)

​

Note:

                    Even if water has passed through a turbine of any kind once, it does not mean that the energy

                    of the position is dissipated in the water.
