Answer:

Representatives of more than 170 countries reached consensus at the Top World Conference on Sustainable Development, in Johannesburg (2002), and at the 3rd World Forum on Water, in Kyoto (2003): all hydroelectric generation is renewable and merits international support. Read, below, the ten reasons leading them to this conclusion.

1. Hydroelectricity is a renewable energy source.

Hydroelectricity uses the energy of running water, without reducing its quantity, to produce electricity. Therefore, all hydroelectric developments, of small or large size, whether run of the river or of accumulated storage, fit the concept of renewable energy.

2. Hydroelectricity makes it feasible to utilize other renewable sources.

Hydroelectric power plants with accumulation reservoirs offer incomparable operational flexibility, since they can immediately respond to fluctuations in the demand for electricity. The flexibility and storage capacity of hydroelectric power plants make them more efficient and economical in supporting the use of intermittent sources of renewable energy, such as solar energy or Aeolian energy.

3. Hydroelectricity promotes guaranteed energy and price stability.

River water is a domestic resource which, contrary to fuel or natural gas, is not subject to market fluctuations. In addition to this, it is the only large renewable source of electricity and its cost-benefit ratio, efficiency, flexibility and reliability assist in optimizing the use of thermal power plants.

the statement which is correct about hydroelectric power plant is that it is a safe renewable source of energy.

Option d.

Explanation:

there is amount of kinetic energy which is present when the water flows in a stream. If the water is blocked by a dam then the kinetic energy is converted into electrical energy.

Hence it is a renewable source of energy. it is a new form of energy as compared to the thermal energy plant. since it is a renewable resource hence it should be used more often.
