A steep growth in offshore wind output helped renewable energy supply a record 35% of German electricity demand in the first half of 2017, adding two percentage points to its share at the same stage a year ago.
Onshore wind was the biggest contributor to German renewable power in the January to June period, with 39 billion kWh, said preliminary figures from the Centre for Solar Energy and Hydrogen Research in Baden-Württemberg (ZSW) and the German Association of Energy and Water Industries (BDEW).
