It has been slightly more challenging to drive on the highway in the evening hours here in the winter months.

Previously the motorways around Copenhagen been reported, but it is no longer the case.

But why is the light disappeared from the major roads? The explanation is actually simple:

the Danish road directorate wants to save energy.

It is in the first instance on a trial basis in a year, writes TV 2 Lorry.

And it is not the only thing, you have chosen to change in order to save energy. The light on the motorvejenes vejvisningstavler is also partly been turned off.

studies have shown that the lighting is effective enough to inform them. In addition, the majority of gps so that they do not need vejvisningstavlerne.

The two things must save 1.850 MWh per year, which corresponds to the consumption of around 400 single-family homes.

the Danish road directorate can save 3.5 million dollars per year.

"It is clear that it also has a meaning that we can save money to reduce the energy consumption from the lighting of our roads," says Michael Aakjer Nielsen, who is head of the department in the road directorate, for TV 2 Lorry.

When the highways were created, it was the idea that, if they were enlightened, then it would be an advantage in the dense traffic.

This new approach should also give a lower CO2-load.
