Q No. 2:
What are the limitations of the energy that can be
obtained from the oceans?
Ans:
Tidal energy, wave energy, and ocean thermal energy are
various forms of energy that can be obtained from the sun. But there are
several limitations to harness these energies. Those limitations are
(i)High dams are required to be built to convert tidal energy into
electricity which incurs lot of cost.
(ii)
Very strong waves are required,
which are not possible all the time.
(iii)
Tidal energy depends on the
relative positioning of the Earth, moon, and the Sun.
(iv) To harness ocean thermal energy the difference
in the temperature of surface hot water and the cold water at depth must be
20ºC or more.
In the first line it should be 'obtained from the ocean' instead of 'obtained from the sun'
ReplyDeleteif i am wrong please tell me
DeleteYou are right, the blogger made a small mistake. It indeed show be 'obtained from the ocean/sea'
DeleteShut up all of you
ReplyDeleteYou can only find mistakes
You don't have courage to answer
My question is
ReplyDeleteAny 2 limitations of harnessing heat energy
Heat energy can be harnessed from the radiations of sun ie, solar energy
DeleteIt has several limitations :
it cannot be harnessed during a rainy day or cloudy day
setting up of solar cell panels require huge amount of infrastructural charges
😳😳😳😳
ReplyDeletewant limitations of wave energy also . so that we can answer 5 mark question..............
ReplyDeleteWell,this answer helped me gain full marks!!
ReplyDeleteThank u😊
Nice answer
ReplyDeleteGood answer
