Renewable energy power plant developer Unit-(e) plans to go public on the Frankfurt stock exchange next month. "Environment stocks have enjoyed a very positive if stormy development over the last few weeks. Our shares will certainly meet with great interest," says the company's Hans Häge expectantly. With some 6000 shareholders, Unit-(e) is currently the largest stockholding company in the environment sector not noted on a stock exchange, Häge adds. Founded in 1996 in Bad Homburg, the company builds and operates renewable energy power stations, with special emphasis on wind and hydro stations. It is preparing an involvement in CO2 credit trading and in desalination plant powered by renewable energy.
