Saving energy when washing clothes
Washing machines consume about 25% of the electric energy for domestic use and every year they produce polluting emissions that have been calculated to be 7 million tons of carbon dioxide, 65,000 tons of sulphur dioxide and 20,000 tons of nitrogen oxides. There are models equipped with a double water intake (hot water and cold water, depending on the selected programme) that allow greater savings, while the “wash & dry” models use a lot of energy.
Some practical suggestions:
- choose models which have a half-load programme, and a thermostat that can be regulated;
- clean the filter and the detergent dispenser drawer using anti-scaling agents (e.g. sodium bicarbonate);
- avoid using the prewash setting and select low temperatures (30-60°C);
- prefer washing in the evening and night because the power plants are used less intensely and can provide energy without any power overload.
