The first bar shows the final energy demand in 2005 (grey), without breakdown to fossil or renewable sources. Bars 2 an d 3 show the development of final energy demand up to 2030, the renewables contribution (always green) according to the scenarios and the fossil & nuclear contribution (always black or grey). The remaining bars provide more details on the figure for 2030. Bar 4 shows the values for OECD (vertically hatched, black is fossil, green is renewable) and non-OECD (horizontally hatched). Bars 5 and 6 show details for OECD (bar 5) and non-OECD (bar 6), broken down to electricity (hatched lower left to upper right) and heat (hatched upper left to lower right). Again renewewables are green but fossils are grey this time.
