Abstract

Many countries and regions in Europe and world wide have set ambitous climate and renewable energy targets to be met til 2020, 2030 and 2050. But with which energy system can such targets be met? What technology combination, to which extend, has to be applied to reach the target in a most cost effective way? Can the targets be reached considering technical, social, environmental and economic constraints? Within Eurac Research a method has been developed, that allows the modellers to give answers to these questions considering the hour by hour energy consumption for a referenece year. The North-Italian region of Southtyrol with its energy consumption, building stock, landscape and natural resources, transportation mix and its climate plan (target 1.5 ton CO2 emissions / capita till 2050) has been taken as a demo model. Technical, social and environmental constraints have been considered with regards to the possible expansion of renewable energy sources for electricity and heat production. The energy efficiency potential has been considered, especially with regard to the existing building stock. Therefore a detailed building clusterisation has been carried out with regard to building type, year of construction, applied construction technologies and possible refurbishment interventions and the related investment cost. Further more the mobility sector and its transition to zero emission transport has been considered. The energy model shows that the target can be reached with a series of measures based on today existing technologies. Considering the cost, not only the target scenarios are not more expensive than todays energy system, but especially a very relevant cost part is shifted from fossil fuels in local investment in energy efficiency and technology development; leading to an important push for the local economy. The model can be applied to other regions and countries.
