2 for solar and sustainable thermal energy systems A member of the Foundation: turnover in 2006 about 110 Mio Euro with technology transfer, consultancy and research Solites is i.a.: Advisor to different ministries in the field of R&D for large solar thermal systems, seasonal heat storage and renewable energy Evaluator for the German Market Incentive Programme for large solar thermal systems Chairman of the German Experts Group on Seasonal Heat Storage

3 German EU-presidentship in the first half of 2007 Resolution of the European Parliament in march 2007: until 2020 Reduction of global warming gases of a minimum of 20 % compared to1990 Increasing energy efficiency by 20 % compared to the trend A share of renewable energy in energy demand of 20 % as a binding target Source: BMU,
