7.Make things easier for your refrigerator and freezer
One of the tips that many people may not know, is that keeping your fridge and freezer full means that they ultimately use less energy when keeping your items cool. Empty space in the freezer or fridge not only wastes your space, but energy as well. Thawing your frozen food before cooking also saves you energy, and use the microwave whenever possible to reduce energy expenditure – it uses less than electric ovens. Reduce cooking time on your cooker by using lids on your cooking pots, and use the economy cycle in your dishwasher, only running it when it is full.
