\nPeople didn\u2019t always have refrigerators to stop food from spoiling. In case of massive power outages, you need to learn ways to keep your food cold without electricity.\n
Depending on your location, it can be hard to use some of these methods. Areas with arid, dry weather excel at keeping food cold with electricity, but humid areas struggle because most off-grid methods for keeping food cold rely on evaporation. Humidity reduces evaporation.\n
Don\u2019t fret! No matter where you live, there are ways to keep your food cold without electricity.\n
Storing food without electricity requires understanding what temperatures food need to be stored. When foods are stored at improper temperatures, especially perishables, it allows the growth and spread of bacteria. If you eat food that\u2019s been held at too-high temperatures, you increase the risk of contracting a food-borne illness.\n
\n
Foods that require refrigeration need to be kept at temperatures at or below 40\u2109 for proper food safety. Examples of foods that need to be stored at these temperatures include:\n
You can store plenty of foods without the use of refrigeration at all. Examples of foods that you don\u2019t need to keep cold include:\n
Here are the most useful ways to keep food cold if the power grid fails.\n
\n
If you only need to keep your food cold for a short period, one of the simplest methods is to wrap the food in a large piece of fabric. The fabric needs to be kept wet with cold water consistently, and then keep the fabric-wrapped food in a shady, cool place.\n
This won\u2019t work for long, but it keeps food cold for a short time frame if you went camping without a cooler. You only can store as much food as your fabric fits, and everything needs to be in waterproof containers.\n

One of the most interesting ways to keep your food cold without electricity is to make a Zeer pot, a primitive yet effective cooler for food. Many regions of the world still use Zeer pots; it\u2019s a beloved method that some use to make ice!\n
It\u2019s two unglazed clay pots \u2013 one larger than the other \u2013 with the small pot inside of the larger one. You must fill the space between the two pots with sand. You put your food inside of the small pot and pour water into the sand.\n
You have to use unglazed pots because it allows the water to soak through, making the clay wet. The water on the surface of the exterior pot evaporates, cooling the sand and the inner pot. Make sure to cover the pots with a wet cloth to help increase evaporation.\n Evaporation is a natural process that cools water, so tap into that to keep your food cold. One method is to make an evaporative refrigerator that keeps food in a place surrounded by evaporating water. Foods kept on the shelves will be cool, but you need to remember to add water.\n If you make an evaporative refrigerator, it\u2019s best to keep it somewhere that it gets hit with a breeze. A breeze increases the amount of air flowing over the wet fabric, increasing evaporation. This method works best in a dry climate; high humidity regions reduce the amount of evaporation.\n Before refrigerators and iceboxes, people learned that it was cooler underground. You probably realize that as well if you have a basement; basements are always colder than upstairs. People used caves at first, but since those aren\u2019t available everywhere, the idea evolved into a root cellar.\n Root cellars were typical a century or two ago; people created underground rooms to store root vegetables like potatoes and carrots. Homes built before the 1960s might have cellars in the basement; my homes have always had cellars. These are cold rooms with doors that people used to store food.\n You can make a root cellar at home! Here are directions to build a root cellar from an old fridge or freezer.\n Do you have a cool stream running near your home? It might be too chilly to take a dip, but streams are perfect for keeping food cool. It\u2019s a trick that campers use, but preppers should know as well.\n Running groundwater stays cool due to evaporation; running water is always cooler than standing water. Water movement exposes more of it to the air, increasing evaporation. So, a puddle isn\u2019t going to keep your food cold without electricity, but a small creek or stream will.\n The biggest consideration is keeping the water and aquatic animals out of your food storage. You\u2019ll need a waterproof, air-tight container to store the food. Otherwise, the water and fish will ruin everything.\n Centuries ago, people built small buildings over springs or wells. These are unique buildings that are noticeably cooler than outside, even in the summer. Water from natural springs is much colder, and you kept food in pottery inside the spring houses. The cold from the spring water keeps the food cold without electricity.\n The problem with building a spring or well house is that it\u2019s major construction and a lot of work. It\u2019s going to cost money to build a spring house, but it lasts for years. Some well-built spring houses survive for well over a century.\n Iceboxes aren\u2019t as old as you might think; they were common in the 1940s and 1950s. This was common right before the invention of the refrigerator. They were kept in the kitchen and used to keep food cool.\n To have an icebox, you need to have ice. Decades ago, an iceman delivered ice to your house from a warehouse. Ice was harvested from lakes and stored using straw and sawdust. Then, you\u2019d put the ice into your icebox and keep your food cold.\n You could use the same idea, but an ice house needs to be built underground to keep ice cold.\n So, if you want to use an ice box, you need an ample supply of ice, and the best way to do that is to make an ice house. To make this work, you need a space underground suitable for storing large pieces of ice. The room needs to be insulated enough to keep food cold.\n The best method is to go as deep underground as possible. Doing this keeps the heat out; the surrounding earth keeps cold temperatures locked inside. Then, you need to gather large ice fragments, which isn\u2019t as easy as it sounds.\n If you don\u2019t have a frozen lake, you\u2019ll need to make these yourself or order them. Line the room with the ice blocks and use sawdust or straw to keep the room as insulated as possible.\n The idea behind a charcoal or coal cooler is similar to a Zeer pot because it uses evaporation to keep the interior temperature cool enough to refrigerate food.\n You make a charcoal cooler by constructing an open timber frame and filling the sides with charcoal kept continually moist. As dry air flows through the damp charcoal, the water starts to evaporate, keeping the inside of the frame cool.\n","protected":false},"excerpt":{"rendered":" People didn\u2019t always have refrigerators to stop food from spoiling.
