Hydroelectric energy potentially is
the result of a fortunate coincidence in which
nature and the need to modernize, are combined
together in an on- going cycle. The cycle being
evaporated, precipitation and concentration.
Having water, though, does not necessarily mean
having hydroelectric potential. To be in usable
form, that water must be in continuous supply,
accessible and concentrated in rivers with a
volume flows and a descent rate, sufficient to drive
generating turbines. The only way that this system
would become non-renewable would logically be
if the lakes, rivers and streams dried up, therefore
the resource of water becoming unavailable. The
likeliness of this happening in our lifetime is next to
nothing, especially in Ontario and Quebec. These
areas have and abundance of lakes and
down-falling rivers. Availability The availability of
water in this area of the world is great. Being able
to have water flowing on a downward slope is
another story.
It is useless if it is not flowing. The
steeper the water flows, the more electricity it will
produce. Hydroelectric plants can be turned into
what are called peaking units in areas where
power plants and high populations exist. That is
because electricity demand in an area can vary
widely over a period of time, sources that can
easily be turned on or off are needed to meet
demand peeks. Environmental Concerns Large
dame change a self-regulating ecological system
into one that must be managed. Placed on a river
without thought to their upstream and downstream
impacts they can bring disaster.

I thought this essay was too good to be true for the 7th grade.
Plaigarized.
