Question

State two advantages of generating electricity by a hydroelectric dam. 

Answer 1

Two advantages of generating electricity by a hydroelectric dam are:

1. Renewable Energy Source: Hydroelectric dams generate electricity through the natural flow of water, making them an environmentally friendly form of energy that does not harm natural resources or rely on fossil fuels.
2. Low Operating Costs: After the dam is completed, the operational and maintenance costs are pretty cheap. Hydroelectric dams can generate electricity for an extended amount of time with low ongoing costs compared to other energy sources.
