moderate increase due to efficiency gains and socio-demographic development significant investments required to replace “old” plantstargets for reduced CO2emissions and increased renewable sourceswindow of opportunity for restructuring of electricity sector and to reduce dependency on imported fuels
Development of European electricity demand and its coverage by power plants already existing in 2000
Concentrating Solar Technologies Robert Pitz-Paal
Development of MENA electricity demand, and its coverage by power plants already existing in 2000
significant increase due to economic and population growth significant investments required for new plantswindow of opportunity for sustainable local electricity and water supplypotential of future electricity exports unique opportunity for closer economic, political and social links with Europe

Renewable energy resources in Europe and MENAin brackets: (max. yield in GWhel / km² /y)
Concentrating Solar Technologies Robert Pitz-Paal
Economic renewable electricity potentials vs. demand in Europe and MENA
renewable resources greatly exceed the present and future electricity demandssolar radiation is by far the most abundant source of energy

Economic renewable electricity potentials vs. demand in Europe and MENA
renewable resources greatly exceed the present and future electricity demandssolar radiation is by far the most abundant source of energy1 km² of desert land may generate 50 MW of electricity1 km2 of desert land may produce 200 - 300 GWhel / year1 km² of desert land avoids 200,000 tons CO2 / yearSolar thermal power plants are the most effective technology to harvest this vast ressource
The electrical energy produced by a solar power plant with the size of Lake Nasser equals the total Middle East oil production

can be integrated into conventional thermal power plantsprovide firm capacity (thermal storage, fossil backup)serve different markets (bulk power, remote power, heat, water) have the lowest costs for solar electricityhave an energy payback time of only 6-12 months
