Question

As a society, we use large quantities of fuel to heat vast amounts of water each day.The heated water is used for a variaty of purposeses, including the genaretion of electrecity. What advateges and disadvanteges are there to using solar energy to heat water? please help..

Answer 1

Advantages
- Solar energy is renewable (i.e. it will not deplete)
- Solar energy is clean (it does not give out pollutants)
- Solar energy is readily available (there is sunshine quite often)

Disadvantages
- Solar energy is difficult to harness (technology is kind of advanced now, but still, the energy absorbed is quite little)
- Solar energy cannot be stored (if we rely totally on solar energy and we can't store it, what are we to do on a dark day or at night?)

Answer 2

wow........
nice job .......

i think ,,

solar energy is costlier to harness than the conventional power sources..........
u need a lot of these cells to harness a good amount of power....
i think tat one cell gives you 0.6V.
it is unreliable as rainy days and cloudy days are always possible...
these so called solar cells are almost useless then.....

advantages---------

hope tat helps

it does't pollute(if u r an actvist of some sort)
and it is replenishable unlike most fuels

Answer 3

It tends to lose efficiency at night.
