Nuon has reported that Dutch households unknowingly waste around 14% of the electricity and 43% of the gas they consume, or an average of E585 per household. The utility said that preventing this wastage could reduce energy bills by around 30%.
The Dutch utility has said that due to the rise in fuel prices, consumers will increasingly need to find better ways of cutting back on energy consumption and preventing waste.
Nuon has said that heat loss through uninsulated floors, roofs and walls, use of old central heating boilers instead of high efficiency boilers, heating empty rooms and placing electrical appliances on automatic stand-by are some of the main causes of energy wastage.
Dutch households pay an average of E1,926 for gas and electricity, and measures to prevent waste could slash energy bills by hundreds of euros a year, according to Nuon.
