Clear communication

The political aims must be communicated clearly and unambiguously, to give investors a solid foundation. It must be realized that the problem in the market is not one of technology, rather of implementation.

Reorientation of regulations

Regulations should be realigned by combining the German Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Act (EEWärmeG). Moreover, landlord and tenant law must be reformed to resolve the split incentive problem.

Consistent incentives

Attractive financial incentives generates seven to eight euros of progressively reduce the subsidy in steps, so as not to overwhelm should be established for investors investment.

Fuel for road, air and ship transportation

Oil is by far the most important fuel for transportation today. Passenger cars and trucks around the world are driven almost exclusively by combustion engines running on either petrol or diesel. All air transport relies on kerosene and special fuel (aviation spirit) obtained from oil. And ocean passenger and cargo transport as well as inland waterway transport also depends on engines running on diesel or heavy fuel oil. Only in rail transport does electricity play a significant role.

Alternatives to petrol and diesel in road transportation

Electric motors are increasingly seen as a promising alternative to combustion engines. Electric automobiles are currently only offered by a few car makers, but are at the top of the development cell vehicles might be another result, manufacturers of diesel The consumption of conventional list of most automobile producers. promising solution.

Visual communication of oil

Graphically depicting oil as a fuel is anything but easy. The main problem is that liquids do not have any shape – except for drops. In 2003, the decision was made to replace the previously used symbol for oil, a barrel, with a stylized drop.

The issue of time also played a role in developing the drop: the more time a drop has to form, the thicker its “belly” becomes. Re- flections were integrated to make the visual representation more in- teresting and easily recognizable.

An orange-brown colour was chosen to represent oil. Variations in colour make the symbol into inde- pendent works of art.

The drop is also used in other colours to symbolize the condensate which is generated in the condensing process.

Experimenting with various styles of reflection on the drops to explore their effect.

The drop symbol was not only used for oil but also to represent condensing technology
