With a "running time" of an estimated 5 billion years, it is practically inexhaustible, its energy potential exceeds around 6500 times the global energy demand. Experts have calculated that an area of 700 x 700 km in Africa would be sufficient to cover the world's energy needs with solar power. In Central Europe, the sun provides as much energy on one square meter as can be obtained from 100 liters of oil. Even if a number of difficult problems have to be solved for a comprehensive supply of solar energy - for example the question of energy transport or the availability of the so-called "rare earths" required for panel production - these are very impressive data that our central star provides here . We need to use this enormous potential of solar power. Photovoltaic systems supply electricity for 20 to 25 years after they have been purchased, while solar thermal energy offers enormous opportunities for heat generation. And all of this is sustainable, noiseless and without any emissions. It is not for nothing that the increase in the photovoltaic market has been so rapid in recent years. Lower Austria, the home of EVN, is a special pioneer here: half of all photovoltaic systems in Austria are here with us. Another advantage in the field of renewable energies that needs to be maintained and expanded. EVN will continue to push ahead with the expansion of solar power in the future. > Print version Sun Locations useful information © 2017, evn naturkraft Vertriebsgesellschaft mbH Accessibility imprint Sitemap
