can anybody give me information on hydroelectricity?

Answer 1

Hydroelectricity is electricity obtained from hydropower. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator, although less common variations use water's kinetic energy or dammed sources, such as tidal power. Hydroelectricity is a renewable energy source.

The energy extracted from water depends not only on the volume but on the difference in height between the source and the water's outflow. This height difference is called the head. The amount of potential energy in water is proportional to the head. To obtain very high head, water for a hydraulic turbine may be run through a large pipe called a penstock.

While many supply public electricity networks, some hydroelectric projects were created for private commercial purposes. For example, aluminium processing requires substantial amounts of electricity, and often dedicated hydroelectric projects are built to serve aluminium electrolytic plants. In the Scottish Highlands there are examples at Kinlochleven and Lochaber, constructed during the early years of the 20th century. In Suriname, the 'van Blommestein' lake, dam and power station were constructed to provide electricity for the Alcoa aluminum industry.

In parts of Canada (the provinces of British Columbia, Manitoba, Ontario, Quebec and Newfoundland and Labrador) hydroelectricity is used so extensively that the word "hydro" is used to refer to any electricity delivered by a power utility. The government-run power utilities in these provinces are called BC Hydro, Manitoba Hydro, Hydro One (formerly "Ontario Hydro"), Hydro-Québec and Newfoundland and Labrador Hydro respectively. Hydro-Québec is the world's largest hydroelectric generating company, with a total installed capacity (2005) of 31,512 MW.

Answer 2

Hydroelectricity utilizes generators to turn the kinetic energy into the spinning motion of the generator, making electricity. But you probably knew that already.

China: The Three Gorges Dam is soon to be the largest dam built, projected to be able to produce 18,200 MW of electricity, enough to power a city four times the size of Los Angeles!

Usually, dams are placed to create artificial lakes behind them, and that pressure, put through a generator, creates electricity. Here is a website with more on hydropower plants work:

I hope I helped!

You have to pick what you think will work for you and your family and go with it. There are 100 different books on how to raise children, 100 different books on how to get your child to sleep through the night. The 'right' method is what you think you can live with. If having one glass of wine a night works for a new mom, then do it. I wouldn't, but that is my personal choice. Same with pacifiers. If you want to give your baby one, go for it. They reduce the risk of SIDS in those first few months as well. I would rather do what I can to keep my newborn alive and worry about braces later. My OB is entitled to have an opinion. I am not required to follow it 100% though. Mommy instinct. You have it, so use it and trust it. What ever method you decide is right for your child is right. (As long as you don't pick up some 1900 parenting book that has some crazy outdated info!)

Answer 4

Live around Niagara Falls and we are still not soley dependent on hydroelectricity so I wish people would stop calling it 'hydro'.
