The document summarizes Germany's Renewable Energy Law (EEG) and its impact on renewable energy development in the country. The EEG established a feed-in tariff system that obligates grid operators to purchase renewable energy at a fixed price for 20 years, providing planning and cost reliability for investors. This has driven strong growth in renewable electricity, with goals of 12.5% by 2010 and 20% by 2020. It has also stimulated significant investment and employment in the renewable energy sector, with €11.3 billion in investment and over 124,000 jobs in 2006. The success of the EEG demonstrates how policy tools can accelerate markets for renewable energy.
