DEEP Update - July 2026

The European Commission's De-risking Energy Efficiency Platform (DEEP) has more than doubled in size, with 52,900 new energy efficiency projects from Germany and the US added in July 2026. Much of the new data is post-2022 and shows that the energy crisis has reinforced, not weakened, the business case for efficiency. In the European data, median paybacks are now shorter than before in both buildings and industry. DEEP now covers 89,400+ projects, with further European datasets from EIB/ELENA and national energy agencies expected later in 2026.
