Hydroelectric Power

For many years now, developing alternative energy sources has been of paramount concern. Though this pursuit has always been important, it is especially important because of growing environmental concerns regarding factors such as dangerous greenhouse gas levels and global warming. Another huge factor in looking for alternative power sources has been the alarming and growing overdependence on limited, non renewable resources such as crude oil. Hydroelectric power has received a great amount of attention for years now, and offers a sufficient enough amount of benefits to make this endeavor well worth furthered exploration. Because although much of the fundamentals have been well established, there is still much that can be improved in terms of efficiency and the methods for the dissemination of power. This type of power is actually the most prevalent type of renewable energy around the world.

First off, simply put, hydroelectricity is electricity generated by hydropower. Hydropower is produced through the incorporation of gravitational force. Gravitational force uses falling or flowing water to create power. Most of this type of power usually originates from dams. Dams help convert potential energy to kinetic energy, using the dammed water to drive a water turbine and generator. The force used to drive the turbine or generator is then converted into kinetic energy which can then be used as live power. The electricity produced through this method can be used for virtually any application. However, one of the main challenges falls under how to most efficiently transfer and spread this power to other utilities and municipalities.

The amount of energy that can be produced from one of these hydro power facilities is in direct relationship with several important factors. The amount of energy that can be produced depends on the quantity or volume of water and the difference in height between the source of the water and the water’s point of outflow (where it leaves the power facility). There have been some really exciting developments in this type of power that concentrate on improving the efficiency and power that can be garnered from a limited volume of water. One such method for doing this involves running water through a sizeable pipe known as a penstock. This helps produce a higher head in the water which in turn produces a greater amount of energy.

Hydroelectricity provides one of our best chances for curbing our use of non renewable resources, and much can be gained by further research into this important area.
