Responsibility when managing the remaining resources Long term power purchase agreement to supply clean ¾ Education for wise Resource Management Energy from MENA to EU All peoples of the earth shall have a realistic chance for MENA shall shift subsidies from Oil/Gas for electricity development. ¾ Energy for Development production to subsidising delivered electricity, giving priority to localy produced components. Collect energy from the deserts, as it is abundant and not used Ground an EU‐MENA company that builds HVDC lines ¾ The Sun gives in 6 hours the Energy used in one year between EU and MENA. Transport the collected energy from the deserts over long Ground an EU Company that that buys clean electricity distances to the users ¾ Via HVDC, an available technology from MENA and sells it to the EU grid. Agree that the delivery of electricity is coupled with a Produce potable water by desalination to satisfy food demand reasonable amount of desalted seawater: ¾ Clean Electricity and use of Waste Heat for Desalination e.g. 20‐40 m³ for each MWh delivered electricity. 23 24 Hani El Nokraschy _.
