Hi dear
How are you? I hope you are good and I'm fine too Alhamdulillah by the grace of Allah Almighty. In the modern world the life without electricity would be difficult and challenging. Now a days in the factories almost all their works depend on the machinary and it would be limited without electricity. We would rely on traditional methods in the absence of electricity such as candles lamps in the night time and we would rely on wells and rainwater. Our communication would be limited without electricity. Best of luck for contest. Wishing you success.
