1. Using the heating or air conditioning like there’s no tomorrow
You will have to sneak a look in the mirror if you are one of those that leave the heating and air conditioning on when you are not at home. Well why not? as the heating “only” accounts for 47% and air conditioning for 18% of the total energy expense in your home…
Is there any sense in walking about your house in January in your beach clothes? And catching a cold in August because your living room feels like you are in Norway?
Stop wasting money: set the thermostat at a reasonable temperature (around 20º in winter for heating and around 26º in summer for air conditioning).
2. You switch on the lights when the sun is still shining
Spain is one of the countries with the most hours of sunshine per year; get those blinds up, open the curtains and smile.
In interior rooms, only switch on the light when you are in them and switch them off when you go out. If you are too lazy, install photoelectric sensors that will switch on when you walk by and switch off after a short while.
3. Leaving your computer on all day
People for some reason believe that computers do not consume much energy, but this is not true: if you leave them on while they are not being used it accounts for 1.6% of the total amount of electricity consumed in your household.
Switch your computer off if you are not going to be using it for more than 30 minutes. Leaving it switched on is a waste of money and you will overheat the machine and wear it out unnecessarily.
