It was 1984 that he set up Enercon, making it the fifth largest company in the sector as its owner and manager. Putting his business acumen at work, he avoided cash-flow and board room problems that were common for Enercon’s competitors. A privately owned company that takes 60% of the market in Germany and does not rents its turbines in the U.S., it has revenues estimated at around $5.34 billion in 2012. Due to health problems, Aloys Wobben retired from the business transferring his 100% stake in Enercon to family trust, the Aloys Wobben Foundation, in October 2012.
