Germany's Umweltkontor Renewable Energy is putting wind on the back burner as the company builds up interests in other renewable energies. It has placed wind into one of four separate business units: wind sun, hydro and bioenergy. Each will be led by specialists and act independently within their markets, the company says. Umweltkontor, based in Erkelenz, built up its business developing wind energy before moving into biomass and solar and is now spreading further afield to tap into development opportunities in all areas of renewables. Its latest move is the acquisition of New Mine Energy, until now owned by the families of Umweltkontor's executive board members Heinrich Lohmann and Leo Noethlichs. New Mine Energy holds stakes in several renewables companies, which include ErSol, a solar cell maker, Gugler Hydro Energy, which builds turbines for hydro stations, Nevest New Energy which develops and builds biodiesel plant and Oxytec Energy, a manufacturer of biomass power plant. Umweltkontor says these companies are either operating profitably or are about to break even. The takeover deal will be put to shareholders for their approval in late October.
