Hydroelectric power is generated by harnessing the kinetic energy of flowing water to turn turbines that drive generators to produce electricity. About 20% of the world's electricity comes from hydroelectric power, making it the largest renewable energy source. While hydroelectricity produces no emissions, it can significantly alter river ecosystems by creating reservoirs and forcing relocations of human settlements. Major hydroelectric power stations in the United States include the Grand Coulee Dam in Washington State, Chief Joseph Dam in Washington State, and the Hoover Dam between Arizona and Nevada.

Aunque es una fuente de energía renovable y barata, la construcción de presas puede afectar negativamente la flora, fauna y ecosistemas acuáticos.
Tidal energy
Tidal energy harnesses the kinetic energy of tidal currents and potential energy of high and low tides to generate electricity. There are two main types of tidal power facilities - tidal barrages and tidal current turbines. Tidal barrages utilize potential energy differences by building dams across tidal estuaries, while tidal current turbines capture kinetic energy directly from tidal stream flows using underwater rotors similar to wind turbines. Tidal energy has advantages of being predictable and free once infrastructure is built, but development has been limited by high construction costs and environmental impacts of large-scale barrages.
Hydro Energy (P Corry)
Hydro energy works by building dams to trap water from sources like lakes and rivers. The water builds up behind the dam, creating pressure. When released through tunnels with turbines inside, the water's pressure turns the turbines to generate electricity. Hydro energy has zero emissions and low operating costs once dams are built, but dams are very expensive to construct and can impact local environments. It provides a more sustainable alternative to power stations that burn fossil fuels and release greenhouse gases, as seen when comparing a coal-powered station to a hydroelectric dam. The document recommends hydro energy as a better long-term energy source due to dwindling fossil fuel supplies and its lower environmental impact.

Student Presentation: The Hoover Dam by Sid and Vic
The Hoover Dam was built on the Colorado River to control flooding and provide water and electricity to surrounding states. It faces engineering challenges due to the canyon it was constructed in and uses concrete moved quickly before it could set. While it generates electricity and prevents floods, it also disrupts natural ecosystems and water quality by creating still water and lowering the riverbed. Some conspiracy theorists believe there are secret government facilities and tunnels connecting it to Area 51.
Hoover Dam Tour
The Hoover Dam was constructed between 1931-1936 under the Hoover administration. It provided employment for thousands of Americans during the Great Depression. The dam created Lake Mead and generates hydroelectric power by transporting 90,000 gallons of water per second through its generators to supply water and power to surrounding states. However, scientists have noted that due to global warming, the water supply from the dam and nearby reservoirs has decreased by half since 2007, which could impact future water demands if the trend continues.
Hydropower
Hydro energy is simply energy that is taken from water and converted to electricity. Hydro energy can be obtained by using many methods of capture. The most common method of using energy from water is a hydroelectric dam, where water coming down through an area causes turbines to rotate and the energy is captured to run a generator.
6 Hydropower
Hydropower harnesses the kinetic energy of flowing water to generate electricity. It has been used for centuries to power mechanical tasks. There are three main types of hydropower facilities - impoundment, diversion, and pumped storage. Impoundment facilities use dams to store water in reservoirs, while diversion facilities channel water through canals without dams. Pumped storage acts like a battery by pumping water between reservoirs. Most dams in the U.S. were built for purposes other than power generation, but many have since added hydropower capabilities. Retrofitting non-powered dams could significantly increase renewable hydropower capacity.
Note for Hoover Dam
The document discusses the negative environmental impacts of the Hoover Dam. It begins by providing background on the dam's construction during the Great Depression. It then examines four main negative effects: 1) riverbed lowering due to water storage, 2) greenhouse gas emissions from submerged vegetation and soil, 3) disruption of local ecosystems and endangered species, 4) changes in water temperature, flow, oxygen levels and salt content downstream. While the dam provided economic benefits, greater consideration of environmental factors is needed for future infrastructure projects.
Hoover dam and the negative effects on environment
The document summarizes some of the negative environmental impacts of the Hoover Dam on the Colorado River ecosystem. It discusses how the dam led to lowering of the riverbed downstream, releasing of greenhouse gases from the reservoir, and destruction of local ecosystems and fish species. Several endangered fish native to the Colorado River were negatively affected by changes in water flow and temperature from the dam. While the dam provided benefits, its construction significantly altered the natural environment of the Colorado River basin.

Dr. PSK-HYDRO ELECTRIC POWER PLANT.pptx
A power plant is a complex industrial facility designed to generate electricity or other forms of power. These plants play a crucial role in supplying energy for various purposes, from lighting homes and powering factories to running transportation systems. In this article, we'll explore the fundamental aspects of power plants, their types, operation, environmental impact, and the future of power generation.
1. **Types of Power Plants**
Power plants come in various forms, each with its own method of generating power:
- **Fossil Fuel Power Plants:** These plants burn coal, oil, or natural gas to produce steam, which drives turbines connected to generators. Fossil fuel power plants are prevalent but contribute to greenhouse gas emissions.
- **Nuclear Power Plants:** Nuclear reactors use controlled nuclear reactions to heat water, creating steam to power turbines. They produce significant energy with low emissions but face concerns about safety and nuclear waste.
- **Renewable Energy Power Plants:** These plants harness energy from renewable sources like sunlight (solar), wind, water (hydroelectric), and geothermal heat. They have gained popularity due to their low environmental impact.
- **Hybrid Power Plants:** Combining different energy sources, such as solar and natural gas, can improve reliability and reduce environmental impact.
2. **Operation of Power Plants**
Regardless of the energy source, power plants follow a similar operational principle:

Hydroelectric energy
Hydroelectric energy is an important renewable energy source, representing 19% of global electricity production. Hydroelectric dams exist around the world, with the largest producers being Canada, the US, and Brazil. Hydroelectric power generates electricity from kinetic energy of flowing water through turbines without producing harmful emissions. Small-scale hydroelectric plants have less environmental impact than large dams. Hydroelectric energy provides clean energy and can also supply water for irrigation and other uses.
Alternative sources of energy
This document discusses various renewable energy sources including solar power, wind power, geothermal energy, hydroelectric power, and tidal energy. It provides details on how each works, including converting sunlight to electricity using solar panels, harnessing the kinetic energy of wind with turbines, using underground heat from rocks to create steam and drive turbines, harnessing the power of moving water via dams to turn turbines, and capturing the kinetic energy of ocean tides with underwater turbines. The pros and cons of each type of renewable energy are outlined.
Hydropower
The document discusses hydropower, which is a renewable energy source that harnesses the kinetic energy of moving water. Hydropower has been used for thousands of years to grind grain and generate electricity. Modern hydropower plants capture the potential energy of dammed water and convert it to electrical energy using turbines connected to generators. The amount of power generated depends on the height that water falls and the volume of water flow. Larger dams and rivers with greater water flow can produce more hydropower.
Hydroelectric power plant (2)
Hydroelectric power (HEP) is an environmentally friendly way to generate electricity by harnessing the kinetic energy of flowing water. It represents 19% of the world's total electricity production. Dams are built to trap water, usually in valleys, and water is channeled through tunnels to turn turbines and drive generators. While HEP has advantages like being renewable and producing no emissions, it also has disadvantages such as the high cost of building dams and potential environmental impacts of flooding large areas.
Hydroelectric Power Plant ppt for electrical engineering
Hydroelectric power plants convert the potential energy of water stored in reservoirs into electrical energy. The main components are:
- A reservoir that stores water higher than the turbine
- A dam that holds back the water and allows it to flow through gates
- A penstock that channels water down to spin the turbine blades
- A turbine whose rotation is converted by a generator into electricity
While renewable, hydroelectric plants have environmental impacts such as disrupted ecosystems and flooding of land.
l1intro to hydroelectric power
This document provides an introduction to hydroelectric power. It explains that hydropower harnesses the kinetic energy of flowing water to generate electricity. It describes how hydroelectric systems work by using turbines connected to generators to convert the mechanical energy of moving water into electrical energy. The document also discusses different types of hydroelectric facilities including high-head dams, low-head run-of-river systems, and varying sizes from large to micro hydro plants. It concludes by giving examples of hydroelectric dams in Arizona.
Tidal energy, Wave Energy, Biofuel.pdf
Tidal energy is produced by the surge of ocean waters during the rise and fall of tides. Tidal energy is a renewable source of energy.
During the 20th century, engineers developed ways to use tidal movement to generate electricity in areas where there is a significant tidal range—the difference in area between high tide and low tide. All methods use special generators to convert tidal energy into electricity.
Tidal energy production is still in its infancy. The amount of power produced so far has been small. There are very few commercial-sized tidal power plants operating in the world. The first was located in La Rance, France. The largest facility is the Sihwa Lake Tidal Power Station in South Korea. The United States has no tidal plants and only a few sites where tidal energy could be produced at a reasonable price. China, France, England, Canada, and Russia have much more potential to use this type of energy.
In the United States, there are legal concerns about underwater land ownership and environmental impact. Investors are not enthusiastic about tidal energy because there is not a strong guarantee that it will make money or benefit consumers. Engineers are working to improve the technology of tidal energy generators to increase the amount of energy they produce, to decrease their impact on the environment, and to find a way to earn a profit for energy companies.
Tidal Energy Generators
There are currently three different ways to get tidal energy: tidal streams, barrages, and tidal lagoons.
For most tidal energy generators, turbines are placed in tidal streams. A tidal stream is a fast-flowing body of water created by tides. A turbine is a machine that takes energy from a flow of fluid. That fluid can be air (wind) or liquid (water). Because water is much more dense than air, tidal energy is more powerful than wind energy. Unlike wind, tides are predictable and stable. Where tidal generators are used, they produce a steady, reliable stream of electricity.
Placing turbines in tidal streams is complex, because the machines are large and disrupt the tide they are trying to harness. The environmental impact could be severe, depending on the size of the turbine and the site of the tidal stream. Turbines are most effective in shallow water. This produces more energy and allows ships to navigate around the turbines. A tidal generator's turbine blades also turn slowly, which helps marine life avoid getting caught in the system.
The world's first tidal power station was constructed in 2007 at Strangford Lough in Northern Ireland. The turbines are placed in a narrow strait between the Strangford Lough inlet and the Irish Sea. The tide can move at 4 meters (13 feet) per second across the strait.
Barrage
Another type of tidal energy generator uses a large dam called a barrage. With a barrage, water can spill over the top or through turbines in the dam because the dam is low. Barrages can be constructed across tidal rivers, bays, and estuaries.
Hidraulic energy
Hydraulic energy is derived from the kinetic and potential energy of falling or flowing water and can be harnessed to generate hydroelectricity, one of the most widely used forms of renewable energy. There are various types of hydroelectric generation such as run-of-the-river, small hydro, micro hydro, conduit, and pumped-storage. Dams are commonly used to collect and control water flow to spin turbines and generate electricity. While hydraulic power has advantages as a clean energy source, dam construction can negatively impact the environment through habitat loss and changes to ecosystems.
Clean and cost effective energy solutions
This presentation is a brief description about various sources of energy like solar, wind, hydro and bio energy.
hydroelectricity and generating electricity
Hydroelectricity is generated by harnessing the gravitational force of falling or flowing water to turn turbines and generate electricity. It accounts for 16% of global electricity production. China is the largest producer, generating over 700 terawatt-hours in 2010, mainly from large conventional dams. Small-scale hydroelectric power below 10MW also contributes, especially in developing nations. While hydro is a renewable and low-cost source of electricity, dams can negatively impact local ecosystems.

This document discusses hydroelectricity and hydroelectric power plants. It begins by providing background on hydroelectricity, noting that it generates 16.6% of the world's electricity through converting the potential energy of water into electricity. It then describes the basic construction and working of hydroelectric power plants. Dams are used to store water in a reservoir, which is then sent through a turbine to spin a generator and produce electricity. The document outlines the main types of hydroelectric power plants, including conventional dams, pumped storage, run-of-the-river, and tide power. Conventional dams have the largest reservoirs while run-of-the-river plants rely on continuous water flow without significant storage. Pumped storage involves pumping
introduction to hydroelectric power
This document provides an introduction to hydroelectric power, including:
- Hydroelectric power harnesses the kinetic energy of flowing water through turbines connected to generators to produce electricity.
- The amount of electricity produced depends on the water's flow rate and head (height of the fall).
- There are various types of hydroelectric systems including high-head dams, low-head run-of-river systems, and small or micro hydro plants.
- Examples of hydroelectric dams and plants in Arizona are described.
Environmental impacts of hydroelectric power
Damming rivers can permanently alter river systems and wildlife habitats. A dam blocks fish migration, stops nutrients from flowing downstream, and changes water quality, all of which negatively impact the river ecosystem. The Iron Gates dams on the Danube River block important spawning sites and do not have fish passes, disrupting the migration and spawning of endangered sturgeon species.
Non conventional energy
This document discusses various non-conventional and renewable energy sources, including solar energy, wind energy, biomass, biofuels, ocean energy, tidal energy, geothermal energy, and hydropower. It provides details on technologies like solar cookers, solar photovoltaic cells, solar water pumps, wind turbines, and how these renewable sources can be used to generate electricity and power things like pumps. The conclusion emphasizes that India has great potential for renewable energy development to help meet its growing energy demands.

Hydroelectricity
- 2. Hydroelectric power, or hydroelectricity, is electrical power that is generated through the kinetic energy of flowing water. About 20% of the world's electrical energy requirement is fulfilled by hydroelectric power. It is the most widely implemented renewable energy generation technology, with the highest market share in the world.
- 3. The dam, lake or reservoir stores water The water goes through the Penstock to the turbines The turbine (propelled by the force of the water being carried in) turns the generator to produce the electricity This electricity is then sent through power lines
- 4. Electricity produced through the hydroelectric energy generation method is produced without any pollution or harmful environmental effects. Neither are any dangerous greenhouse gases emitted. Hydroelectric power plants generate renewable energy. This means that the source of the energy won't run out anytime soon. Since running water, unlike fossil fuels, will always remain a constant, hydroelectric energy has no expiry date.
- 5. Hydroelectric energy plants alter the environment in their surroundings to a great extent. River ecosystems are based on the continual flow of water. The backwaters from reservoirs severely change the conditions, turning it into a swampy, lake biome. The flood from the backwater also forces human settlements, sometimes several villages, to relocate.
