Transcript of Hydro

"Roughly speaking, one gallon of water per second falling one hundred feet can generate one kilowatt of electrical power" Kinetic Energy Provided by nature itself! "Roughly speaking, one gallon of water per second falling one hundred feet can generate one kilowatt of electrical power" "Roughly speaking, one gallon of water per second falling one hundred feet can generate one kilowatt of electrical power" Provided by NATURE itself Hydroelectric power is a
renewable resource rainfall replenishes the water in a reservoir reduce greenhouse gas emissons Oil will continue to
pollute our air and
waters if we do not figure out another way to supply ourselves with energy How It Works kinetic energy obtained by water falling large distances to drive turbines and generators to produce electricity dams are then built to hold back large bodies of water, so that when the water flows
through the pipes it goes through the turbines with great energy the water flows through the pipe,
and then hits the blades or paddles in
a turbine, causing them to turn the turbine is a lot like the kind
used in a regular coal or gas power
plant but instead of using steam to turn
the turbine, water is used the turbine spins a generator to produce electricity the electricity can then be sent to your home your school to factories and businesses pros and cons involves using large quantities of water and numerous acres of land time and large amounts of money prime locations have already been built upon IMPACTS the area in which it's built water quality may become muddy negatively affects the fish habitat fish may also become entrapped and or killed in the turbines themselves dependant upon precipitation without precipitation or other bodies of water,
the plant would be completely useless plenty of places available where a hydroelectric plant could be built While hydroelectric power has it's problems, it can still be a safe and sustainable source of electricity developing fish-friendly technology at dams progressing run-of-the-river turbine technology reducing environmental effects can be possible Alternatives acid rain?
thermal pollution from coal plants?

built a Low-Impact Hydropower station in the city of Columbus the O'Shaughnessy Dam is on the Scioto River and contains two turbines Low-Impact hydropower systems,
also known as micro-hydro systems,
work very similar to their much
larger counter-parts differences micro's can hook directly into a home or business
as a back-up source during outages these micro systems can produce enough electricity to run several home appliances Low Impact Hydropower Institute Certified Considered low-impact Criteria for this certification requires the facility to protect or lessen the impact upon ...river flows, water quality, fish passage and protection, watershed protection, threatened and endangered species protection cultural resource protection and recreation I thoroughly support the use of hydroelectricity; however, hydroelectricity cannot be the only source of electricity for this nation. We still need, at this point, to use fossil fuel. However, fossil fuels are limited. Someday we will run out of fuels such as oil, but we will always be able to rely on water. If we utilize the hydroelectricity facilities we currently have, some of the requirements for power can be fulfilled using this virtually clean source. I personally live in an area that has financially benefited from the building of a hydroelectric power plant. Upon building this plant people were displaced but were compensated for the loss of their home and land. It is true that the fish were being killed going through the turbines. However, this did bring profit to my hometown because oddly enough, the dead fish parts, provided by the turbine, draws more fish to the area for feeding. This provided adequate fishing conditions for the local fisherman and tourists. Even so, our town decided that the killing of fish was not worth the profit it brought in from fisherman. A net was installed around the turbines, thus comletely eliminating the killing of fish. Hydroelectric facilities have been around for a number of years. Their obvious value to our nation's power requirements is easily seen. Over time technological improvements have been made as well as diminishing negative impacts upon the environment. currently, our nation has taken a stand for more 'green energy'. According to scientists, certified low-impact hydropower plants are a sustainable energy source for those who want to live more 'green'. The End!! :) References
