Massive, and growing rapidly. The second derivative is debatable (i.e. the growth may be slowing) and it may not be fast enough, but Germany heavily subsidized renewables both through subsidies and minimum prices for renewable energy generation very early (which is one of the reason for the absolutely perverse electricity prices, which ironically make gas heating more attractive). Random quote I found: "In 2020 renewable energy sources produced more electricity than all fossil fuels (coal, gas, oil) together and now provide 45.3 percent of German electricity demand." Electricity demand is just a part of energy demand though, so getting all heating to e.g. heat pumps will be a major effort.
