The house has been in the center of our lives since the dawn of civilization. It has also become in the last years a center for most of our expenses, from taxes to electricity and from water to heating.
In the US a typical household pays around 1400 $ a year for electricity while a family in Germany would pay around 1200 Euros per year. This does not include the cost for heating and cooling which can add to the final bill around 40%. Off course each individual case may vary but for the purpose of this example we will consider an average yearly expenses for energy for a house in the US of 2000 $ and 1700 Euros for Germany. In Romania we could assume that the average yearly expenses for energy are around 800 Euros.
From this amount we waste around 25% of the energy or per year around 500 $ in the US, 425 Euros in Germany or 200 Euros in Romania.
Considering that private houses are responsible for between 26% to 40% of the total Energy consumption, depending on the country, we reach the conclusion that we are wasting between 6.5% and 10% of the total Energy produced. That in the US translates, in an optimistic scenario, to around 278 billion kWh, enough energy to power more than 2.5 million household in the US per year. At an average price of 12 Cents per kWh that is more than 33 billion $ wasted every year. And the situation is similar in Europe, for example in Romania we are wasting 4.2 billion kWh per year. At an average price of 9 cents per kWh this means more than 380 million Euros losses every year. We could build 100 km of highways with this money, a couple of world class stadiums or buy 20 F-16 Fighting Falcon. And in addition to the billions we are wasting every year we are also having a huge impact on the environment by releasing, just for the energy that we do not use, more than 191 million metric tons of CO2.
This figures are based on average energy consumption data from the past available online. For details please check resources.
So where is this huge waste coming from and what can we do about it?
Well to answer this we should first have a look at the graph bellow to see what are the main consumers of energy in a typical household
As we can see the main energy consumption is related to heating and cooling with more than 50% of total consumption if we consider also water heating and electronics with more than 35% in total energy consumption.
