When it comes to washing up, pack the dishwasher full and choose the economy programme.
A kettle uses a lot of energy, but you can still save energy with it: Only fill it with as much water as you need; if you need water to cook pasta, heat it in the kettle first. When cooking on the cooker, put the lid on the pot so that water boils faster. Are you cooking a dish in the oven? Then use the baking energy for the entire dish. For example, don't just cook fish fingers in the oven, but add potato wedges and vegetables to the dish. When it comes to washing up, pack the dishwasher full and choose the economy programme. When washing dishes by hand, do not rinse under running water.
