Question

why are we looking at alternative sources of energy?​

Answer 1

Answer:

Because fossil fuels are being used at large scale and they are non renewable sources of energy, they will disappear after some time. After the depletion of non renewable sources of energy we will be left with nothing, hence we are trying to develop alternate sources of energy.

Answer 2

: Required Answer

$\longrightarrow$ The reason why we are looking at alternate sources of energy is because the fossil fuels are non-renewable sources of energy, i.e. they are not available in large quantities and cannot be replenished. Fossil fuels will get exhausted if their consumption is not controlled. Therefore, it is better to switch to alternate source of energy
