This is the world’s first tourism development project integrating multi-energy complementation system, which takes regenerative tourism and sustainable development as the core and features clean energy and environmental protection. It builds many modules like photovoltaics, energy storage, power grid, seawater desalination, water supply/wastewater pipe network, solid waste/wastewater treatment, communication and district cooling to achieve 100% green pollution-free energy supply, thereby lessening Saudi Arabia’s dependence on petroleum economy and contributing to its economic diversification.
