Hydroelectric Energy :: essays research papers

Hydroelectric energy potentially isthe result of a fortunate co-occurrence in whichnature and the need to modernize, are combinedtogether in an on- going cycle. The cycle beingevaporated, precipitation and concentration.Having water, though, does not necessarily meanhaving hydroelectric potential. To be in us able-bodiedform, that water must be in continuous supply,accessible and concentrated in rivers with avolume flows and a stemma rate, sufficient to drivegenerating turbines. The only way that this bodywould become non-renewable would logically beif the lakes, rivers and streams dried up, thereforethe resource of water becoming unavailable. Thelikeliness of this hazard in our lifetime is next tonothing, especially in Ontario and Quebec. Theseareas have and copiousness of lakes anddown-falling rivers.
