High-tech for Solar Thermal Power Generation Made in Germany NUMOV: Solar Industry in the Republic of Cyprus Karl-Heinz Funken (karl-heinz.funken@dlr.de) DLR Solar Research, Cologne, November 29, 2010 Folie 1
Development of European electricity demand and its coverage by power plants already existing in 2000 moderate increase due to efficiency gains and sociodemographic development significant investments required to replace old plants targets for reduced CO 2 emissions and increased renewable sources window of opportunity for restructuring the electricity sector and to reduce dependency on imported fuels Folie 2
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 plants window of opportunity for sustainable local electricity and water supply potential of future electricity exports unique opportunity for closer economic, political and social links with Europe Folie 3
Renewable energy resources in Europe and MENA in brackets: (max. yield in GWh el / km² /y) Folie 4
renewable resources greatly exceed the present and future electricity demands solar radiation is by far the most abundant source of energy Economic renewable electricity potentials vs. demand in Europe and MENA Folie 5

Key messages Amongst the renewables: solar energy has the highest potential wind, biomass, geothermal, hydropower alone are insufficient! CSP can meet mid power demand even today CSP can be hybridized with fossil or bio-fuels Solar process heat is another option for concentrating solar systems Folie 19
