What are the pros and cons of hydro energy?

There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not.

Hoover Dam, built in the 1930’s, is located in the Black Canyon area of Colorado River. This facility is capable of generating 2,074MW and came with a price tag of $49 million. The cost of hydroelectric power is dependent on a lot of factors.

The flow and head determines the potential energy of a waterfall. Hydroelectric energy can be defined as a form of hydropower where the motion of running water (kinetic energy) is converted into electricity. Construction of dams in specific areas with the ability to generate vast amounts of power can present a myriad of challenges. Even though hydroelectric power plants comes with many benefits to the end user, variables exist that can hold back their development. With that reason in mind, it’s prudent to weigh the pros and cons of this form of energy when looking to construct one.

The force of falling water pushing against the turbine's blades causes the turbine to spin. A water turbine is much like a windmill, except the energy is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy. The photo on the right shows the Alexander Hydroelectric Plant on the Wisconsin River, a medium-sized plant that produces enough electricity to serve about 8,000 people.

In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community. Nothing is perfect on Earth, and that includes the production of electricity using flowing water.

In 1881, street lamps in the city of Niagara Falls were powered by hydropower. Hydropower and pumped hydro energy storage converts the energy of moving water into electricity. Until the advent of cell phones, telephone companies were considered utilities because they had service areas awarded by governments with little or no competition.

Hydro description

Moving water is therefore powerful source of energy that can lighten cities, towns and even countries. The initial production utilized timber, granite block and low dam of rock construction to gather water from surface runoff and rainfall into a reservoir. The water was then channeled to a pipe and then to a water wheel (turbine). The channeled water fell on a turbine blade spinning it and the connected shaft. The shaft was connected to a standby generator which produced electricity when rotated.

Then a generator converts the mechanical energy from the turbine into electrical energy. A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy.

The rotating turbines then use the kinetic energy of moving water which in turn causes the magnets inside the generator to rotate and generate electricity. The water then exits the turbine and is returned to the stream below the dam.

In this article I’m going to explain how hydroelectric power plants work. A micro hydropower plant has a capacity of up to 100 kilowatts.

How many types of dams are there?

Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17% (International Energy Agency) of total electricity production. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).

To protect disadvantage people from losing heat in the winter or cooling in the summer, governments set review procedures that utilities must follow before they can disconnect service. You can pay your bills using a check or an online payment system, in much the same way you pay credit card bills. Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. The water cycle is driven directly by solar energy. When the sun heats the water in the ocean, some of the water on the surface is vaporized.

Conduct electricity from the hydropower plant to homes and business. "12 mega dams that changed the world (in Norwegian)" In English Teknisk Ukeblad, 17 January 2015. Chief Joseph Dam near Bridgeport, Washington, is a major run-of-the-river station without a sizeable reservoir.

What is good about a dam?

Three common types of concrete dams are: gravity, buttress and arch. Gravity: Concrete gravity dams are the most common form of concrete dam. The mass weight of concrete and friction resist the reservoir water pressure.

What is hydropower?

Hydro description
  • The transformer converts the electrical energy from the generator to a high voltage.
  • During off-peak periods, some of the extra power available is supplied to the generator operating as a motor, driving the turbine to pump water into an elevated reservoir.
  • There are very little fluctuations in terms of the electric power that is being by the plants, unless a different output is desired.
  • We have already started using up suitable reservoirs for hydroelectric power plants.
  • A micro hydropower plant has a capacity of up to 100 kilowatts.

Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also. Converts the mechanical energy from the turbine into electric energy.

Where Does Hydroelectric Energy Come From?

Hydro description

Since about 1980, the rate of reservoir construction has slowed considerably. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area. Hydropower represents about 17% (International Energy Agency) of total electricity production. Compared to among others fossil fuels and nuclear energy, hydroelectricity is much safer.

The farther the water falls, the more power it has. Generally, the distance that the water falls depends on the size of the dam.

Still, the hydroelectric plant will have to operate for a long time to recoup the money injected in the construction. Energy technologies instituted and run in environmentally sensible, economically viable and socially responsible models symbolize the greatest concepts of sustainable development. This means development models in the present day that addresses individuals’ needs without affecting the capability of coming generations for tackling their own needs. Hydroelectric power is among these energy technologies.

Hydroelectric Power Water Use

Below are other science topics associated with hydroelectric power water use. Hydropower is the most important and widely-used renewable source of energy. Water is everywhere, which is fortunate for all of humanity, as water is essential for life. We have already started using up suitable reservoirs for hydroelectric power plants.

Hydro description

Then, during periods of peak demand, the water is allowed to flow down again through the turbine to generate electrical energy. Pumped-storage systems are efficient and provide an economical way to meet peak loads. dams that impound rivers, thereby raising the level of the water behind the dam and creating as high a head as is feasible. In some dams, the powerhouse is constructed on one flank of the dam, part of the dam being used as a spillway over which excess water is discharged in times of flood.

When an intake opens, the immense weight of the reservoir forces water through a channel called the penstock towards a turbine. The water rushes past the turbine, hitting its blades and causing it to spin, converting some of the water’s kinetic energy into mechanical energy.

It stores energy by pumping water uphill to a reservoir at higher elevation from a second reservoir at a lower elevation. When the demand for electricity is low, a pumped storage facility stores energy by pumping water from a lower reservoir to an upper reservoir. During periods of high electrical demand, the water is released back to the lower reservoir and turns a turbine, generating electricity.

A hydroelectric power station converts the kinetic, or movement, energy in flowing or falling water into electrical energy that can be used in homes and businesses. Although most energy in the United States is produced by fossil-fuel and nuclear power plants, hydroelectricity is still important to the Nation.

Facts About Hydropower

How expensive is hydropower?

Dams pro vide a range of economic, environmental, and social benefits, including recreation, flood control, water supply, hydroelectric power, waste management, river navigation, and wildlife habitat. Dams provide prime recreational facilities throughout the United States.

So we can figure out how many people our dam could serve by dividing the annual energy production by 3,000. Since electric energy is normally measured in kilowatt-hours, we multiply the power from our dam by the number of hours in a year. We contact the United States Geological Survey, the agency in the U.S. that measures river flow, and learn that the average amount of water flowing in our river is 500 cubic feet per second.

Hydro description

The most common utilities include electricity, natural gas, water, garbage pickup and sewer service. You get electricity and gas from private companies that are heavily regulated by local and state governments, and your choices of service providers will be very limited. People who live in or near towns or cities normally get water, sewerage and garbage service from the town or city. If a person depends on well water and a septic system, these are not utilities per se, as they do not receive monthly bills and are personally responsible for repair and upkeep.

Below are just some of the benefits that hydropower has over other methods of providing energy. So our local irrigation or recreation dam could provide enough renewable energy to meet the residential needs of 990 people if we added a turbine and generator.
