Let us first of all have a closer look at MOBILITY.
In the vast country of the USA, mobility has always been very important.
Originally, Native Americans moved across the USA on horses.
The horses also carried the houses of American Indians: the tepees.
It was important that these tepees could be transported very easily, because the Indians did not live at the same place for a very long time.
They were constantly moving around across the American Plains.
When the first cars were produced, people in America were able to move around more comfortably.
In this picture we can see a FORD Model T, also known as Tin Lizzie.
The Tin Lizzie is generally regarded as the first affordable automobile, the car that opened travel to the common middle-class American;
The Model T was the first automobile that was mass-produced on moving assembly lines.
Here we can see that cars can also be transformed into houses.
Nowadays, not just people are mobile in their cars in the US . Houses are mobile, too.
As you can see here, whole houses can be transported from one place to another on a truck.
Let us now have a closer look at what effects access to CHEAP ENERGY has on housing in the US:
In this picture you can see the skeleton construction of a typical American house.
In the US, oil prices are still quite low (in comparison to Europe).
As a result, the houses in the US do not tend to be insulated as much as our houses in Austria - although winters can get very cold in the US.
