Question 1 Report
Fig. 1 shows a proposed micro-hydroelectric scheme in a mountain valley in Nepal. Water is diverted through a channel to a small turbine house before returning to the river. The scheme is intended to supply electricity to three isolated settlements that currently use kerosene lamps and diesel generators. An international charity has offered grants, while villagers will provide labour and maintenance.
(a) State one renewable resource used by the scheme. [1]
(b) State two groups that could be involved in this development project. [2]
(c) Explain one advantage of using a small hydroelectric scheme rather than diesel generators in these settlements. [2]
Answer Details
(a) The renewable resource is flowing river water, or hydropower. [1]
(b) Two groups that could be involved are local villagers and the international charity or NGO. Government, engineers, and an electricity company are also valid. [2]
(c) Small-scale hydroelectricity uses renewable water rather than diesel fuel. It therefore produces fewer greenhouse-gas emissions than burning diesel, helping reduce environmental impact. It also avoids repeatedly transporting diesel along difficult mountain roads. One explained advantage is required. [2]
