Energy Mix of the Future

Global energy demand might grow from today s value of 12 billion toe to 35 billion toe in 2100, and renewables may then make up 35% of the total. The share of nuclear power is expected to be 20%. Fossil fuels will still be important but with a smaller relative share of approximately 30% in 2100. The remaining 15% may be covered by other sources (waste, fuel cells, oil shale, etc.) 

Fuel Non-conventional oil (oil sand and oil shale) Non onventional natural gas (tight gas, coal-bed gas, aquifer gas)  

Scenarios of future energy consumption and energy mixes are needed, but we should keep in mind that they are probably uncertain, such as shown in Table 5.1.14 for global energy demand and in Table 5.1.15 for energy consumption in the USA, comparing forecasts from the 1970s for 2000 with the actual values.
