What is hydro energy PPT?
Hydroelectricity generates electricity by harnessing the gravitational force of falling water. In 2006, hydroelectricity supplied around 20% of the world’s electricity. Most hydroelectric power stations use water held in dams to drive turbines and generators which turn mechanical energy into electrical energy.
What are advantages of hydropower?
Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy.
What are the different types of hydropower?
There are three types of hydropower facilities: impoundment, diversion, and pumped storage.
What is hydro energy system?
hydroelectric power, also called hydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity.
What is the working principle of hydro power plant?
The water turbine changes the kinetic energy of the falling water into mechanical energy at the turbine shaft. In simple words, falling water spins the water turbine. The turbine drives the alternator coupled with it and converts mechanical energy into electrical energy.
What is wind energy PPT?
Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. Wind turbines are mounted on a tower to capture the most energy.
What is the advantage and disadvantage of hydropower?
Pros and cons of hydropower
| Pros of hydropower | Cons of hydropower |
|---|---|
| Renewable energy source | Some adverse environmental impact |
| Pairs well with other renewables | Expensive up-front |
| Can meet peak electricity demand | Lack of available reservoirs |
What is an example of hydropower?
Types of Hydroelectric Power This fast flowing water turns the turbines, and the generator system converts this kinetic energy into electrical energy. An example of a hydroelectric power dam, is the Kielder Water reservoir, located in Northumberland, operated by RWE Npower and is the largest system in England.
What are four types of turbines?
While turbines can be classed as either impulse or reaction according to the way they function, there are four broad types of turbines categorized according to the fluid that supplies the driving force: steam, gas, water, or wind.
What is hydro energy in simple words?
Hydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed.
How do we get hydro energy?
Hydroelectric power is produced with moving water At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity. The facilities may have a weir in the water course to divert water flow to hydro turbines.
What do you need to know about hydro power plants?
Hydro power plants Hydro power plants The principle the water conduits of a traditional high head power plant Arrangement of a small hydropower plant Water intake Dam – PowerPoint PPT presentation
What are the social issues of hydro power?
5. SOCIAL ISSUES Relocating people from the reservoir area is the most challenging social aspect of hydropower, leading to significant concerns regarding local culture, religious beliefs, and effects associated with inundating burial sites.
What are the environmental impacts of hydroelectric power?
Environmental Impacts Hydroelectric power includes both massive hydroelectric dams and small run-of-the-river plants.
Which is the largest hydroelectric power station in the world?
In 2006, hydroelectricity supplied around 20% of the world’s electricity. Most hydroelectric power stations use water held in dams to drive turbines and generators which turn mechanical energy into electrical energy. The largest hydroelectric power station in the world is the Three Gorges Dam in China.
