I want to share two tips for survival without electricity.
First ' Take a clay pot , fill it with water, and wrap a wet cloth around it. Place it somewhere with airflow (like near a window). As the water evaporates, it naturally cools the pot and the water inside. So you will get Cooler drinking water without electricity and it will work as A mini “fridge effect” to keep fruits/veggies fresh longer
Second At night, use a mirror or shiny surface to reflect moonlight or candlelight to brighten your space without extra fuel. This practice will generate thrice more brightness.
