Hydro power is when water flows down a tube or pipe in a dam and hits the turbine causing it to spin rapidly. The power from the turbine being spun generates electrical current in the transformer which is used to power homes and electronic devices. The Mechanical energy from the water moving is passed through a transformer and turned into electricity.

Pressured water from a reservoir behind a dam flow down a tube when the control gate is opened and hit and spin a generator is usually the main form of hydro power. The pressure from the water in the reservoir causes the turbine to spin rapidly and generate electricity.

Using turbines on a river bed, one can create as much energy as a small charcoal fire without the green house gas emissions by a simple river current. This is another way of generating electricity, without using a dam.

Water from a dam reservoir flows into a tube down the dam and spins the turbine. The spinning turbine generates electricity to power homes without excess pollution unlike fossil fuels and some other forms of energy.

Hydro power is a basic concept. Water flows down a tube from a holding point, and spins a turbine on its way down and is forced through a narrow pipe creating greater pressure. The force of the pressurized water going down the tube spins the turbine rapidly creating an electrical current that is passed through a transformer and sent to a power house. From there the energy is supplied to homes and businesses to provide power the people around it.
