Nowadays, there is a massive requirement of generators everywhere, may it be a commercial sector or domestic. The generators are the backup of electricity, as all humans are highly dependent on electrical equipment these days.  Imagine, a power cut happens suddenly, and you were about to submit your assignment before the deadline, and you don’t have any power backup at your place! Which will lead to failure in your final exam, sounds horrifying?  It’s the reason why one should always have an alternative source of energy.
