Fossil fuels today represent around 85% of the global primary energy demand. The trend is that fossil fuels – oil, coal and natural gas – will continue to meet most of the world's energy needs in the foreseeable future (IEA, 2012b). Fossil fuels will remain the Ezetimibe source of energy through to 2035 in all IEA scenarios, although their respective share in the mix in 2035 varies markedly. It is no table that renewables, except hydro and bioenergy, still meet less than 1% of the total primary energy demand. Their share is expected to rise, but in absolute figures the amount of fossil fuels will also increase, and therefore related CO2 emissions. There is nothing in the on-going trends that contradicts this conclusion, although there are of course a lot of uncertainties, mainly political, regarding fossil fuels as pointed out in the World Energy Outlook 2012 (IEA, 2012b). However, the belief that renewables like solar and wind energy can play a central role to reduce GHG emissions just does not seem realistic. The strong global demand for fossil fuels is influential in international relations, where conflicts can suddenly change the arena. This can already be seen in developments in the Middle East, Northern Africa and Eastern Europe, and in more recent crisis in Ukraine. A global economic crisis and/or conflicts escalating to war could suddenly decrease GHG emissions. This is, however, a mitigation option, which no one would wish for.
