Hydroelectric power in our lives
Effects on the world around us
The size of the reservoir created by a hydroelectric project can differentiate a lot, depending largely on the size of the hydroelectric generators and the difference of the land. Hydroelectric plants in flat areas tend to use a lot more land than those in hilly areas or canyons where deeper reservoirs can hold more water in a smaller space.
At one extreme, the large Balbina hydroelectric plant, which was built in a flat area of Brazil, flooded 2,360 square kilometers.
water is lost through evaporation in dammed reservoirs at a much faster rate than in active rivers.
segments of the river downstream from the reservoir can dry out. so most hydroelectric operators are required to release a minimum amount of water at certain times of year. If not released right, water levels downstream will drop and animal and plant life can be damaged.
Life-cycle Global Warming Emissions
Global warming emissions are produced during the installation and dismantling of hydroelectric power plants..
Hydro power is fueled by water, so it's a clean fuel source, meaning it will not pollute the air. Hydroelectric power is a domestic source of energy, allowing each state in the USA to produce their own energy without being reliant on international fuels . fish and other wildlife species can be damaged by the turbines in the hydro electric power plants. water
Costs and Materials
The materials you will need are water and turbines and a dam How much does a hydro power system cost to build?
It’s quite difficult to make exact cost to build hydro systems because of the different combinations of head (the change in water levels between the intake and discharge) and maximum flow rate, and how that affects the maximum power output and choice of turbine type.
it would costs around $263812.87 for a 25 kw power out put $468306.87 for a 50 kw power output $825781.11 for a 100 kw power output $1503265.05 for a 250 kw power output and a whopping $2497636.500 kw for a 500 kw power output , You’ll notice that very small hydro power systems are disproportionately expensive, and this is because hydro projects of any size have to include a substantial fixed-cost element at the design and consenting stages, and a lesser degree during the installation stage.
