Answer
Hydroelectric power
Explanation
The method used in area 4 is hydroelectric power. Hydroelectric power is generated by using the potential energy of water stored in a dam situated usually in a remote area with a river valley to turn a turbine. The downstream side of the dam creates a descent which causes a high pressure. This pressure then used to turn the turbine linked to the generator resulting in electricity. However, a major potential problem associated with hydropower is flooding of farmland which is exactly mentioned in energy source/environment 4 potential problem. This usually happens during the building of a large reservoir and dam which is necessitated by the needs of a hydroelectric power plant. This gives an additional strong support that the method used at location 4 was hydroelectric power.
