Climate change and the energy transition are high on the European agenda. Last year, 'Fit for 55' was presented, a plan to deliver the EU's 2030 climate target on the way to climate neutrality and to reduce greenhouse gas emissions by at least 55% by 2030. Following the war in Ukraine, REPowerEU was launched, with the ambition to rapidly reduce dependence on Russian fossil fuels and fast forward the green transition. These initiatives imply that millions of households and businesses will need to make investments in order to save energy and use alternative energy sources.
