Abstract
Since 1950 changes have taken place in the use of the various forms of energy and the consumption and the self-reliance of the different countries. The finite fossil energy sources, the uncertain production and the long lead-times are important factors for the future. The Dutch energy situation presents particular characteristics. In the Netherlands oil will be the most important energy source by 1985. The system is likely to adjust to the greater expensiveness of energy. Transport mainly consumes oil products.
