Abstract

The energy supply needs to be CO2 free, save and affordable. Fossil fuels especially oil but also gas will become more scarce and expensive. The fossil energy source coal will last much longer. If we would however burn all the coal we find, the level of greenhouse gases would rise steeply. If we take climate protection seriously, the energy and mobility system needs to be completely changed. Coal power plants must become more climate friendly, renewable energy must be used more intensively. In addition, we need to save more energy and produce electricity and heating together via Combined Heat and Power Plants (CHPs) and develop and apply alternative fuels and sustainable mobility concepts. Very important is that the policy develops a road map towards an energy efficient, sustainable and climate friendly economy. Renewable energy needs to be promoted and energy saving needs financial incentives. Especially the energy savings potentials of buildings are huge. Financial incentives for estate owner can be improved by tax savings, by direct financial support and better options to shift costs towards renters. Also in the area of mobility many things can be improved: public transportation and rail traffic needs to be better supported, emissions trading need to cover air transportation and the German car manufacturing needs to become sustainable. Die Energieversorgung muss klimaschonend, sicher, aber auch bezahlbar sein. Fossile Energien allen voran Öl und später auch Gas werden knapper und teurer. Die fossile Ressource Kohle steht uns zwar noch sehr lange zur Verfügung, die Verbrennung verursacht jedoch klimagefährliche Treibhausgase. Wenn wir Klimaschutz wirklich ernst nehmen, muss das Energie- und Mobilitätssystem umgebaut werden: Die Kohletechnologie muss umweltschonend werden, die erneuerbaren Energien müssen ausgebaut werden, wir müssen viel mehr Energie einsparen und verstärkt Wärme und Stromproduktion gleichzeitig produzieren und nutzen sowie klimaschonende Antriebsstoffe und -techniken einsetzen. Es ist ein langer Weg zu gehen, den wir heute beginnen müssen. Wichtig ist, dass die Politik die Weichen hin zu einer energieeffizienten, nachhaltigen und klimaschonenden Wirtschaftswelt ebnet. Die erneuerbaren Energien müssen weiterhin gefördert werden, es sollten finanzielle Anreize zum Energiesparen geschaffen werden. Insbesondere im Gebäudebereich liegen ungeahnte Energieeinsparpotentiale. Durch gezielte finanzielle Förderung, Steuerersparnisse und verbesserte Möglichkeiten der Kostenüberwälzung für Immobilienbesitzer können hier die richtigen Signale gesetzt werden. Auch im Bereich Mobilität gibt es viel zu verbessern: Schienenverkehr und ÖPNV müssen stärker unterstützt werden, der Flugverkehr in den Emissionshandel aufgenommen werden, und die deutsche Autobranche muss zukunftsfähig gemacht werden.
