Yes. As I said, there are a number of incentives for the actual end user to buy the systems from the manufacturers. The government also launched in the early 1990s a resource program into renewable energy, but unfortunately, in Germany research into energy is divided between I think three or four different ministries, and responsibility constantly switches in terms of energy research. And renewable energies got the worst of that—they switched most often—so even though the German government overall is very proud of its achievements in terms of our R and D, it could have done a much better job on that end.
In total the subsidies, the public moneys, that go into research and development are much lower for renewable energies than for all other sources of energy, and it has been like that for a very long time. If you're interested in that, I can pull up the latest figures on that.
Last but not least, a large amount of turnover that you don't see in these 25.5 billion euros is from exports. These exports, I guess, are in a range—I would have to make a wild guess—somewhere between another 15 billion euros and maybe a little more. They have also been supported with public moneys in terms of marketing support abroad, information about foreign markets in order to encourage German industry to go abroad and sell in other markets. But the leverage of these small investments the government made in these technical support measures is very high. It's about a factor of a thousand. So one euro that is put into one of these market support measures is leveraging a thousand euros in terms of exports. So there are some highly cost-effective measures the government can take in order to facilitate this type of growth.
Another example I might give is eastern Germany, which has had to build up a whole new infrastructure of industry over those 20 years. There have been effective measures of regional development from the European Union as well as the German government, so some regions in eastern Germany are now called the solar valley because so many solar firms have located there and generate decent growth and job opportunities—areas like Bitterfeld, which used to be a very run-down chemistry site.
