The European Commission published a "toolbox" last week, which outlines the national measures that governments can take to tackle soaring energy prices. But countries are still split over the issue. German Chancellor Angela Merkel says the rising prices should not hinder Europe's transition to renewable energies. European Commission President Ursula von der Leyen said the EU needs more clean energy in the future, such as solar and wind, but she also stresses that nuclear and natural gas are equally needed as stable sources in the transition.
