Last year, the European Union generated more electricity for the first time from renewable sources than from fossil fuels, according to an analysis by the research organizations Agora Energiewende and Ember.
The share of sustainable energy was 38 percent last year and that of fossil energy 37 percent.
Nuclear energy accounted for the remaining 25 percent.
The use of solar and wind energy rose to just under 20 percent, the use of coal is only just over 10 percent.
According to the report, the corona crisis has had only a limited impact.
Had the overall demand for power not declined so sharply last year, the trend towards renewable sources would have been even stronger.
The researchers speak of a milestone in the European energy transition.
They do point out that the transition is not going fast enough to achieve the goal of 55 percent CO2 reduction by 2030 and climate neutrality by 2050.
Biomass is included in the segment of energy from renewable sources.
Some experts question how sustainable this form of energy really is.
The Netherlands is making up for part of the gap
Of the individual Member States, Denmark obtains the largest share of electricity from wind and sun: 61 percent.
In Slovakia and the Czech Republic, that percentage is less than 5 percent.
The Netherlands is mentioned in the analysis as a major climber.
The share of wind and solar energy was on the small side here for years, but rose by no less than 40 percent last year, almost to the European average.
Nevertheless, the Netherlands remains one of the countries with a relatively large share of fossil energy, partly because - unlike some other EU Member States - nuclear energy has almost no share.
