DM611498_COVER_dos7 29/11/06 10:19 Page 1 The World Energy Technology Outlook report (WETO-H2) provides a coherent framework to analyse the drivers and constraints in world energy to 2050, energy development and CO2 emissions. WETO-H2 presents three different scenarios for the future world energy system up to 2050: the Reference case, the Carbon constraint case and the Hydrogen case. The report highlights the main future energy, environmental and technological challenges that Europe will have to face in order to stay competitive while promoting new clean energy technologies.
