[Domestic large-scale impact turbine runner off the production line] On May 16, 2023, the first domestic 150-megawatt-class large-scale Pelton turbine runner was successfully rolled off the production line in Deyang, Sichuan, marking a major breakthrough in the core components of my country's Pelton turbine. The runner that rolled off the production line this time weighs about 20 tons and has a maximum diameter of about 4 meters. It will be used in the Tianwanhe Jinwo Hydropower Station in Ya'an City, Sichuan Province, and is expected to be put into operation in early June. It is understood that the impact turbine uses a special water guide mechanism to rush the water from the pressure pipe to the runner, causing it to rotate and drive the generator rotor to generate electricity. It is mostly used in hydropower stations with high water head and small flow. Edit/Ma Xue

• [Europe: Install solar on the roof of all new residential buildings from 2030]
• The European Parliament has formally adopted the revised Energy Performance Directive for Buildings (EPBD), which will become law after formal approval by the Council of Ministers. The directive requires all new residential buildings in the EU to be powered by rooftop solar from 2030, and public buildings and non-residential buildings will need to be phased in according to their scale and technical and economic assessments. The EPBD aims to reduce energy consumption and greenhouse gas emissions in the building sector in line with the EU's goal of achieving climate neutrality by 2050. Currently, the building sector accounts for 40% of the EU's total energy consumption and 36% of greenhouse gas emissions. The aim of improving energy efficiency in buildings is to enhance energy independence and sustainability in this sector by reducing the use of imported oil and gas fuels. Under the forthcoming rules, all new buildings occupied or owned by public bodies will need to be zero-emission by 2028, and all new buildings from 2030 onwards. Member States need to clearly plan the measures taken to decarbonize heating systems in order to phase out fossil fuels in heating and cooling by 2040. From 2025, stand-alone fossil fuel boilers will no longer receive subsidies, but hybrid heating systems that use renewable energy will be eligible for financial incentives. Editor/Xu Shengpeng

• [Germany plans to build fusion power plants]
• Germany's Federal Research Minister Bettina Stark-Watzinger has announced a new fusion research funding program aimed at paving the way for the construction of the first fusion power plant in Germany by 2040. The Federal Ministry of Education and Research (BMBF) has long supported fusion research at the Max Planck Institute for Plasma Physics (IPP) in Garching and Greifswald, the Karlsruhe Institute of Technology (KIT) and the Jurich Research Centre (FZJ). "This institutional funding is complemented by the second pillar of the new Project Funding Scheme," the ministry said. "The project funding aims to advance the technologies, components and materials required for fusion power plants in the first phase by the early 2030s. The second phase focuses on integration into the power plant design. The funding program is open to technology and addresses so-called magnetic confinement and laser fusion technology." In order to achieve the construction of fusion power stations as soon as possible, the program is essentially application-oriented collaborative research as a form of public-private partnership. Projects on specific sub-technologies will be carried out jointly by research institutions, universities and industry. This allows new findings from the research to be applied at an early stage and know-how to be transferred to domestic industries for further use, the ministry said. Editor/Xu Shengpeng
