World Energy Outlook: a Comparative Study

Differen world energy outlook with different horizons (2035, 2040 and 2050) show that demand for primary energy will increase. The energymix in 2050 will mainly be fossil based although the share of theses fuels will decrease. Accorging to some forecasts, energy consumption will increase more than 50 percent during next 30 years which most of this growth belongs to non-OECD countries. In supply side, the fastest growth will belong to natural gas and renewables. According to World Energy Council (WEC), Environmental sustainability، energy security, and energy equity are three pillars ofthe energy trilemma. The WEC has built two scenarios for fulfillment of these goals for world energy outlook to 2050. The more consumer-driven Jazzscenario has a focus on energy equity with priority given toachieving individual access and affordability of energy through economic growth. But more voter-driven Symphony scenario has a focus on achieving environmentalsustainability through internationally coordinated policies and practices. In Jazz scenario, the growth of energy consumption is more than Symphony scenario. In addition, the growth of renewables in Symphony scenario is twice of Jazz scenario.
