	Hydroelectricity - Wikipedia, the free encyclopedia
		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.
		Canada is the world's largest producer of hydro power and produces over 70% of its electricity from hydroelectric sources.
		Apart from a few countries with an abundance of it, hydro capacity is normally applied to peak-load demand, because it can be readily stored during off-peak hours (in fact, pumped-storage hydroelectric reservoirs are sometimes used to store electricity produced by thermal plants for use during peak hours).

		Hydro-electric power is electricity produced by the movement of fresh water from rivers and lakes.
		Hydro-electric power stations are therefore situated where they can take advantage of the greatest fall of a large quantity of water- at the bottom of a deep and steep-sided valley or gorge, or near the base of a dam.
		Originally, hydro-electric power stations were of a small size and were set up at waterfalls in the vicinity of towns because it was not possible at that time, to transmit electrical energy over great distances.

	Hydro-Electric Power (Site not responding. Last check: 2007-09-06)
		By the beginning of the 20th century, hydro-electric power was considered to be the energy supplier of the future for the province of Ontario.
		Although construction of the power facilities at Big Chute were hampered by transportation difficulties, the plant was finally operating in July, 1911, with a capacity of 3300 hp.
		This private power system of some twenty subsidiary companies became the Central Ontario Region of the Hydro Electric Power Commission of Ontario after it was purchased by the province in 1916.

	ENERGY FACTS: HYDRO-ELECTRIC POWER
		Hydro power is currently the world's largest renewable source of electricity, accounting for 6% of worldwide energy supply or about 15% of the world's electricity.
		During periods of peak electrical demand, water from the higher reservoir is released through turbines to the lower reservoir, and electricity is produced (Figure 2).
		As well, many small hydro electric sites were abandoned in the 1950's and 60's when the price of oil and coal was very low, and their environmental impacts unrealized.

	HYDRO-ELECTRIC POWER
		The first use of moving water to produce electricity was a waterwheel on the Fox River in Wisconsin in 1882, two years after Thomas Edison unveiled the incandescent light bulb.
		As electricity demand soared in the middle years of this century, and the efficiency of coal and oil fuelled power plants increased, small hydro plants fell out of favour.
		Power plants of this type may utilize a low dam or weir to channel water, or no dam and simply use the "run of the river".

		In power units with vertical shafts the thrust bearing is charged by the weight of both the rotating equipment and the water pressure on the turbine wheel which could be considerable at a plant with high vertical drop.
		Owing to the electro-mechanical installation of hydro electric power plants having traditionally been part of the very initial equipment to be insured, the standard of insurance for such installations has reached a level which hardly allows for any substantial revisions or improvements.
		In this respect, hydro power is better than burning coal, oil or natural gas to produce electricity, as it does not contribute to global warming or acid rain.

	Hydro Power (Site not responding. Last check: 2007-09-06)
		Perhaps the most appealing aspect of hydro-electric power is that since the energy of the falling water ultimately derives from the sun (see How it works for more information) it is a source of energy that should last as long as Sol continues to shine.
		Another great attraction of hydro is that it is relatively cheap: 1 kW/hour might cost 4 cents to generate while the same amount of energy produced via photo-voltaic cells might you as much as 30 cents.[1] In some ways, hydro plants are quite environmentally friendly as well.
		Another key advantage of hydro power is one that I have already mentioned: the ability to store energy (in the shape of water) in times of low-demand.

	Hydroelectricity (Site not responding. Last check: 2007-09-06)
		Hydroelectricity, or hydroelectric power, is a form of hydropower, (i.e.,the use of energy released by water falling, flowing downhill, moving tidally, or moving in some other way) to produce electricity.
		Most hydroelectric power is currently generated from water flowing downhill, but a few tidal harnesses exist that draw power from the tide.
		Hydroelectric power is generated at dams or other places where water descends from a height, or coasts with a large tidal swing (such as the Bay of Fundy).
