When refrigerators hit the market within the late 1800s, it was an enormous leap ahead for civilized living. It supplied a simple answer to the issue of micro organism-laden, disease-causing previous meals, not to mention the problem of losing money shopping for food that went bad before individuals could eat it all.
With all the plain advantages of preserving meals by way of artificial cooling, it is laborious to think about folks voluntarily giving up their refrigerators. Nonetheless, a current, small-scale motion inside the ultra-“inexperienced” group has folks doing simply that. A typical refrigerator purchased in or after 2000 makes use of about 450 kilowatt-hours of electricity per 12 months (an older model would possibly eat two or three times that) [source: Wisegeek]. Those kilowatt-hours translate to roughly 660 pounds (272 kilograms) of carbon dioxide, which is about the amount of CO2 you emit by burning 35 gallons (132 liters) of gasoline in your car [sources: EPA, Slate]. Acknowledged merely, driving your automobile about 800 miles (1,287 kilometers) emits the identical quantity of CO2 into the ambiance as cooling your food for a year. They’re attempting to cut back their carbon footprint by foregoing the icebox.
For individuals who select to surrender the fridge, the greenhouse gas emissions associated to running the equipment outweigh the benefits of refrigeration. Is it simpler than we predict? To most individuals residing within the developed world, although, going with out a refrigerator looks as if a almost impossible factor to do.
In this text, we’ll learn the way some eco-dedicated souls are residing fridge-free, and we’ll learn the way the rest of us can inexperienced up our refrigeration habits with out getting fairly so drastic.
To begin, it appears giving up the refrigerator doesn’t necessarily imply giving up cold food. You store your leftovers, dairy merchandise, fruits and vegetables to keep them secure to eat and assist them last longer.
However, longevity aside, a number of the things you refrigerate could do Ok at room temperature. And whereas fruits, vegetables, cheese and butter may keep edible for weeks in the refrigerator, should you plan to eat them inside a week, they’ll do just wonderful on the counter in a cool, dry place. Some have a system of freezing bottles of water in a mini-freezer after which utilizing those bottles to keep a larger cooler cold. Most of them use a cooler, a small freezer or each. First, few individuals who have unplugged their refrigerators truly go without any cooling at all. Others find a great ice source and simply reside with a cooler at house, with no electric cooling source in any respect. And if somebody lives in a cold climate, storing yogurt or cottage cheese exterior on a chilly day is a viable option. That method, they’ll still retailer issues like meat and milk at dwelling. After that, though, you’ll most likely be dealing with mushy produce and moldy dairy, and you’ll need to throw them out. Condiments like ketchup and mustard, which lots of us are in the habit of storing within the fridge, sometimes do not must be refrigerated.
No matter what the cooling source, individuals with out a refrigerator have to vary the way in which they purchase meals at the shop. And shopping for smaller amounts can imply spending more cash. In other phrases, no more trips to the Costco meat division. Same goes for other perishables: Instead of a 3-pound (1.3-kilogram) bag of apples, you have to limit yourself to just some; gallons of milk could should be replaced with quarts because of area limitations within the cooler. Buying rooster for dinner means shopping for precisely how much chicken you’ll be able to eat, as a result of you do not want to must store leftovers. So funds have to issue into the choice to unplug the fridge. Throwing away meals that’s gone dangerous can cost you money, too.
There are a number of other actual-world issues that additionally have to be balanced towards the electricity you save by giving up a refrigerator.
In fact, it doesn’t. For one factor, the associated fee-benefit commerce-off could not work out, since you may end up coping with numerous rotten meals that goes to waste. For an additional, shopping for food in smaller quantities can imply you eat more packaging and burn more fuel driving to the grocery retailer more often. In comparison with other main house appliances, it uses very little power.
Lastly, for individuals who go the freezer route, the small power savings achieved by unplugging the fridge is decreased by plugging in the freezer. A small chest freezer (less than 6.Four cubic feet or 0.18 cubic meters) can devour more than 200 kilowatt-hours per yr [supply: EERE].
So, what to do if you would like to scale back your refrigeration footprint, however you’re not giving up the fridge? However you can also use higher refrigerator habits (which won’t value you practically as much), such as cleaning the coils yearly to keep the unit working effectively; testing the door seal to make sure it’s tight; deciding what you need to eat earlier than you open the door so you don’t stand there losing cold air; and retaining the fridge relatively full, which helps the temperature bounce back sooner after you open and shut the door. First, you possibly can replace an old unit with a brand new, high-efficiency Power Star rated appliance.
And, as with most technologies, keep your eyes open for improvements. A Cambridge, Mass., group is working on a fridge design that runs on a diesel (or biodiesel) generator and solar panels, and that cools using thermoelectrics instead of toxic Freon. It requires no electricity at all. U.Okay. scientists are attempting to revitalize an old refrigerator invented by Albert Einstein and colleague Leo Szilard, which has no moving elements and runs only on pressurized gasses.
Eco-pleasant refrigerators like these are far from hitting the shelves, but you by no means know — in 20 years, home refrigeration may very well be as inexperienced as a picnic cooler.
