L'energia nei paesi in via di sviluppo Ralph Gebauer Monday, May 31 st, 2010 Le filiere dell'energia Fondazione Internazionale Trieste
ICTPs mission Foster the growth of advanced studies and research in physics and mathematics, especially among researchers from developing countries; Provide an international forum for the exchange of information and ideas among scientists from the North and South; Maintain excellent research facilities for visitors, associates and fellows, principally from developing countries, who participate in the Centre's research and training activities.
Example: Ethiopia Population (2005): 73 million TPES (2003): 238.4 10 9 kWh Share of renewables: > 92%
Example: Ethiopia Population (2005): 73 million TPES (2003): 238.4 10 9 kWh Share of renewables: > 92% Share of renewables, excluding combustible renewables: < 1% This portion is mainly hydro-electricity from large installations (mainly unreliable)
Photovoltaics 140 % of present annual end energy consumption of FRG (3*10 18 J) 250% of present end energy use of Western Europe (1.8 * 10 19 J) 350 % of present annual world energy consumption (10 20 J) 450 % of extrapolated annual world energy consumption in 2030 (2* 10 19 J) Percentage of total Sahara area: 7.6 %4 5.4 %3 0.7 %2 0.12 %1 Required Land Areas using 10 % efficient photovoltaic modules Arbeitskreis Alternativenergie Tübingen (Herausg.): "Energiepolitik vonunten", Fischer, Frankfurt/Main, 1982
Key challenges for research in new materials: Energy conversion which is: Scalable (10 – 30 TW, in 2050) CO 2 free Affordable Energy storage which is: Scalable Affordable "Energy engineering" knowledge: For all
