 Renewable biogas is a gas created from mainly three sources, livestock manure, landfill gas, and some type of waste material, either agricultural waste or forest residues. And it's important because it provides a renewable opportunity to displace natural gas in specific applications like power generation or end-use applications like in a furnace or in your stove. A quarter of the municipal solid waste stream consists of organic waste. And 95% of that goes into landfills today where it just decomposes and produces methane, much of which is released to the atmosphere. We could divert that from the landfills and send it to anaerobic digesters where it can produce renewable biogas. Then we can take the residuals from that process and produce compost and other soil products that can go back to the earth and restore it. Well, using renewable biogas allows us to offset our reliance on fossil fuels. Whether we use it for vehicle fuel, whether we use it for electricity production, whether we use it for directly, for thermal needs. It's a very aggressive part of our strategy to be a sustainable utility and to deliver renewable energy to our customers. Biogas serves as a great option to put into the pipeline and use for any end-use, whether it's for sending to our power plants for renewable energy generation, whether it's direct use at our customers' homes or whether it's for transportation. So it's very versatile once it's actually in the pipeline and we've got lots of reasons to procure it. Biogas is the look-it-on-the-block in Germany among the renewable energy industries. It's currently the most growing renewable energy source in Germany. We probably have, by the end of this year, 5,000 biogas installations in Germany. And they power roughly 3.8 million whole sources. Biogas is probably the sector among the renewable energies that has created the most jobs in Germany. In the year 2009 we have 300,000 jobs already in the renewable energy sector. A large share of that is in biomass. We have a lot of revenue from that.
