Hi dear!
How are you? Hope you are fine and I'm fine too Alhamdulillah by the grace of Allah Almighty. Without electricity life would be difficult and challenging. It is difficult to survive in the absence of electricity but other primary sources Can be helpful such as candles in the night, for the preservation of food canning and drying can be effective. Without internet communication would be limited but to communicate we can adopt traditional methods such telegrams an letters.best of luck for contest.
