It's important to differentiate between energy (which includes industrial and process heat, internal combustion engines, residential heat etc) and electricity. The later is only a quarter of the total. A lot of coal and nat gas burning would need to be replaced to produce glass, iron, steel, a range of chemicals, paper etc. before we could talk about the EU getting 37% of its energy from 'renewables'... Which by the way includes hydro-power (no longer scalable) and burning wood chips from deforestation (which is simply unsustainable).
