ADVANTAGES: 1. Once a dam is constructed, electricity can be produced at a constant rate. 2. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high.
Dams produce hydroelectricity, and the step to creat that, is very easy. What you need to build a dam is a river with a large drop in elevation-such as a waterfall.The dam stores lots of water behind it in it's reservoir-or a lake-type thing as a result of decreased water flow.Near the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.In the tunnel, the water flows down a large drop-called a penstock-and gravity causes it to gain speed.ear the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.
