In recent years, the European Union has introduced a series of policy measures to accelerate the deployment of renewable energy and promote the green transformation of energy. The European energy think tank Ember recently released a report stating that in 2023, the proportion of renewable energy generation in the EU reached a historic high of 44% of total generation. Among them, wind and solar power generation accounts for 27% of the total power generation. At the same time, the EU's fossil fuel power generation in 2023 decreased by 19% year-on-year, less than one-third of the total power generation. The EU is implementing a rooftop solar program, which involves installing solar panels in new public and commercial buildings and residential areas in stages.

In recent years, the European Union has introduced a series of policy measures to achieve the 2050 carbon neutrality goal and strengthen support for the transition to clean energy. In May 2022, the European Union released the "Joint Action Plan for Affordable, Safe, and Sustainable Energy in Europe" (hereinafter referred to as the "Plan"), proposing to increase the EU's energy efficiency target from 9% to 13% by 2030, provide an additional 210 billion euros by 2027 to break through key clean energy technologies, and strive to increase the proportion of renewable energy in EU energy consumption to 45% by 2030. The EU has developed the EU Solar Strategy within the framework of this plan, proposing to double the installed capacity of solar photovoltaics from 2020 to over 320 gigawatts by 2025 and approach 600 gigawatts by 2030. At the same time, the "rooftop solar energy plan" will be implemented, and solar panels will be installed in new public and commercial buildings and residential areas in stages. EU countries have also successively launched relevant measures to promote the growth of photovoltaic power generation. Last year, the Irish government announced the cancellation of value-added tax on the supply and installation of solar photovoltaic panels, resulting in over 60000 households installing rooftop solar systems. Wind power is also a key focus of renewable energy construction in the European Union. In October last year, the European Commission issued the European Wind Power Action Plan, proposing a series of support measures to promote wind power development, including improving the digitalization of licensing processes, improving bidding design and financing assistance in the electricity market, and large-scale talent training. Among them, accelerating the development of offshore wind power has become one of the focuses of the plan. Last April, the leaders and energy ministers of nine European countries held a meeting in Ostende, Belgium to agree on a new commitment to building offshore wind energy in the North Sea. The meeting passed the Ostend Declaration, which plans to increase the offshore wind power installed capacity of countries near the North Sea to 120 gigawatts by 2030 and above 300 gigawatts by 2050. In 2023, Poland achieved its first investment in a commercial offshore wind farm and officially began developing offshore wind power. One of the largest offshore wind farms in the world, the 1.5 gigawatt Kust Zuid offshore wind power project in the Netherlands, was officially put into operation last year. In order to adapt to the continuous growth of renewable energy generation, the European Commission also proposed a grid construction action plan in November last year.
