Hydroelectricity, a renewable source of energy, is basically electricity found through hydropower. Hydroelectricity is generated from the energy that is falling over from a dam or generators that are specifically driven by water turbines. The largest hydroelectricity facility is located in a place called "Itaipu" on the Argentina, Brazil and Paraguay border and produces an average of around 75 million megawatts per annum. It took approximately 16 years to build this facility.
Hydro-Québec, a Canadian company having a total installed capacity of approximately 32000 Megawatts, is today the world's largest hydroelectricity generating company as per the year 2005. The largest producer of hydropower is China whereas Canada produces more than 70-75% of its electricity from hydropower. The other major countries producing electricity from hydropower are Norway (almost 100%), Brazil (92% according to 2005) and Austria (67%-70%). Large hydroelectric projects can disrupt the surrounding aquatic ecosystems.
