Efficient cooking methods, such as putting lids on pots, simmering gently instead of boiling vigorously and using a pressure cooker, can save half the greenhouse gas generated during cooking.Cook toast in a toaster instead of under the griller: reduce greenhouse gas emissions by up to three quarters.An electric kettle or gas cooker generates about one kilogram of greenhouse gas for every 10 litres of water boiled, half as much as using a microwave or an electric cooktop.Pre-prepared meals in open aluminium foil trays with sides less than four centimetres high can be reheated in a microwave oven with much lower greenhouse gas emissions than in an electric or gas oven (ensure the aluminium does not contact the sides of the microwave oven – stand it in a larger plastic container to avoid sparks).Up to 90% of the energy used by ovens is wasted: use alternatives - microwave, electric frypan, pressure cooker.Fan-forced ovens generate up to 35% less greenhouse gas than conventional ovens and more items can be cooked at the same time, as heat is more evenly distributed around the oven.For maximum efficiency when cooking with electricity, use pots and pans with flat bases that match the size of the element.Thaw food in the fresh food compartment of the fridge before cooking. Cooking time is reduced and less greenhouse gas is generated.For small households, cooking in bulk, freezing the food and then reheating in a microwave oven cuts greenhouse gas emissions – and saves time. |
