In July, Germany's Ministry for the Environment, Nature Conservation, and Nuclear Safety released a draft progress report on the country's Renewable Energy Sources Act. The Act, adopted in 2000, establishes an advanced "feed-in tariff" in Germany, enabling any company or individual who meets the technical and legal requirements to sell renewable electricity into the power grid for a guaranteed, long-term price for each kilowatt-hour sold. "The Renewable Energy Sources Act is the most important and successful instrument to promote the expansion of renewable energies in the electricity sector," the report notes.
The report's findings indicate significant advances in Germany's renewables sector, including:
The report also finds that the net economic benefits of renewable electricity in Germany amount to about 6 billion euro ($8.5 billion) per year. While renewable electricity costs the nation's consumers an estimated $3.3 billion euros ($4.7 billion) annually in differential costs (the cost premium of renewable over conventional power) and the provision of energy balancing (balancing electricity generation and demand), the government estimates that its benefits are far higher. The economic benefits of renewable energy totaled more than 9 billion euro ($12.7 billion) in 2006, including fuel-import savings of 0.9 billion euro ($1.27 billion), avoided environmental and health damages worth approximately 3.4 billion euro ($4.8 billion), and a decline in wholesale electricity prices amounting to 5 billion euro ($7 billion).
By some estimates, renewables will provide about 14 percent of Germany's gross electricity consumption by the end of this year, well ahead of official targets for 2010. As a result of this success, in July the German government increased its targets for renewable energy to 27 percent of electricity by 2020 (up from 20 percent) and at least 45 percent by 2030. Germany's success with the feed-in law has also prompted several other countries around the world to adopt advanced feed-in laws. Just last month, a Michigan legislator was the first to introduce a true feed-in law in the United States.
