Some people see wind energy as a clean alternative to fossil fuels. Others believe that utilizing this renewable energy resource
Y_Kistochka [10]

Answer:

Renewable energy resource as an obstacles for the growth of migratory salmon populations: It is now believed that the reduce access to spawning grounds and nursery areas, leading to a decrease in migratory fish populations is due to the dam structures of large storage-type schemes, which can create great obstacles for the movement of migratory fish species.

Explanation:

  • Storage-type schemes ( big dams) can significantly change the downstream flow regime,and may also alter water temperature and quality, and even make it inhabitable for fish to live.
  • As the storage of water can be linked with high evaporative losses, which in turn results in high life cycle water footprints compared to other sources of electricity.

<u>Run-of-river (ROR) schemes are HEP schemes: </u>

They operate without water storage, using the flow within a river channel.They are ecologically friendly and do not disturb the natural mechanism for the migrating salmons.

Working Principle:

They are normally used to regulate water levels, which allows a proportion or part of flow to be diverted down a secondary channel to a turbine before it is returned to the main channel further downstream.

There are some modern turbine types used in ROR HEP(hydroelectric power) schemes, which are also designed to allow fish to pass through the system unharmed if the fish do pass through the intake screens.

Which 2 examples may be converted into fossil fuels after being buried under pressure for a long period of time?
krok68 [10]

Answer: -plants  

-animal waste

Explanation:

Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
