Renewable energy
� hydro 5 TW=5x1012 W
� geotherm. – up to 20 TW
� wind – 50 TW (27 % area of Earth)
� biomass 20 TW (31% area of Earth)
� sun 600 TW Natan Lewis, Caltech
generation of 20 TW at 10 % eff. requires 8.8 % area of USA
Just 0.7% of Europe's total land covered with photovoltaic modules would provide
100% of the continent's electricity needs!
2010: 15 TW
2050: 28 TW
Present and expected energy demand
1
energy coming from the sun per year
uranium
total reserves:
oil
Energetical resources:fossil and nuclear fuels compared to the energy from the Sun
uraniumoil
gas
coal
world consumption/year
2
Electricity from renewable resources
3
European installed capacity (MW)
4
Global installed PV capacity (MW)
