21 Energy efficiency and smart infrastructure The laser in Măgurele is hosted by an ecological building, currently the largest building in Europe supplied with energy from unconventional sources - 3.9 MW geothermal energy generated by 1,080 water wells dug at 120 m depth each, covering an area of about 27,000 m . The borehole 2 thermal energy storage (BTES) conditioning system used at the ELI-NP centre is an European frst for such applications and ranks fourth worldwide.
