Dead End for Fossil / Nuclear Energies
The environment is substantially loaded by the past use of fossil / nuclear energy supplies.
Climate change caused by carbon dioxide emissions has already been discussed. Furthermore, quantities of powerful energy-rich steam are fed through the cooling towers in fossil / nuclear power plants. In countries without sufficient water availability, the water resources vital to agriculture and the population are thus removed. In some areas, these problems are dangerously aggravated by climate change.
The increasing intensity in the depletion of fossil / nuclear fuels leads to the destruction of ever larger water resource systems. The Earth's surface has been extensively damaged, including by the harmful chemicals accumulated in many areas of development.
Follow-up costs also arise for the national economies due to environmental load, for example because of the dangers to health.
The previous energy supply system using fossil / nuclear fuels is based on resources that are in the possession of fewer countries. As a result of the associated monopolistic structures, the importing countries are easy to blackmail.
On the one hand, disappearing fuel resources cause global conflicts such as wars over raw materials and, on the other hand, increasing costs for exploration and extraction. The transport routes, extensive in some parts, are extremely vulnerable to wars, terrorism and catastrophes.
The causes named will inevitably lead to an explosion of annual costs as well as the dramatic impoverishment of developing countries that are poor in raw materials.
The fossil / nuclear energy supply is fundamentally tied up in central supply structures. This allows supply companies to create price dictatorships.
Investment in central power plants and transport systems remains limited. There are only low economic incentives for the national economy.
The necessary repeated transformations of the energy sources from raw materials extraction through supply to the end user involve low efficiency. In addition, high capacity reserves are required in order to be able to compensate for losses of supply units, if necessary. According the energy flow chart (as of 2002), currently only 31 percent of established primary energies in Germany are used. However, this number includes a 34 percent loss by the end user.
