The ability to know today how much wind power will be produced over the next few days provides a decisive advantage over the energy market. Thanks to a new system developed by German University spin-off energy & meteo systems, it's now possible to obtain an accurate forecast of the energy output from wind parks for up to ten days in advance.

The gold medal for new wind power production in 2007 goes to the United States. More than 5,200 megawatts of capacity were installed there, a new world record. New factories are to ensure further growth, provided the promotion criteria are extended in time.
