The EU solar energy strategy proposed under the REPowerEU plan aims to make solar energy a cornerstone of the EU energy system. Boosting renewable energy is also an important part of the European Green Deal in the context of the green transition towards climate neutrality. Solar energy is affordable, clean and has been the fastest-growing energy source in the last decade. It can be used for electricity and heating, while also helping reduce EU dependency on energy imports by replacing them with domestic production. EU measures to boost solar energy include making the installation of solar panels on the rooftops of new buildings obligatory within a specific timeframe, streamlining permitting procedures for renewable energy projects, improving the skills base in the solar sector and boosting the EU's capacity to manufacture photovoltaic panels.
