2. Refrigerator – everything in its place
Who doesn't love when the fridge is full of delicacies? As it happens, a full refrigerator also makes good ecological and economic sense. An empty unit consumes more electricity. And refrigerators make up 10% or more of a household's energy consumption. Though they're a central part of our homes, we often don't use them as well as we could. The most important savings tip: a temperature of seven degrees is enough. Each degree you don't cool saves you 6% on electricity. But don't forget that the temperatures inside the refrigerator are uneven. It's warmer on top, colder on the bottom. So you should place your fish and meat on the bottom and less delicate products like cheese on top. It's also warmer in the vegetable drawer and in the covered compartments designed to hold eggs and butter.
3. Meat – less is more
Vegetables and fruit are vitamin-rich and healthy. So it pays to prepare vegetarian meals from time to time to keep your family fit. And it helps the environment even more. Meat places a burden on the environment – up to 10 times more than vegetables and fruit. After all, animals must first be fed: according to a WWF study, roughly 15,000 liters of water are used for one kilo of beef. There are other ways you can save based on what you eat. On average, a single household wastes 15% of its food. So check your food before you throw it away. If a family changes its eating habits, it could easily save around 1,000 Swiss francs a year.
