Chapter 1: Energy prognosis until 2030; reserves; transport fuels
POLITICAL INFLUENCE
POPULATION
WORLDWIDE GDP (+ 2.7 %) IS GROWING FASTER THAN ENERGY CONSUMPTION
ENERGY CONSUMPTION IS GROWING BY 1.2 % P.A
KEY FACTOR ENERGY EFFICIENCY
ELECTRICITY GENERATION REMAINS THE BIGGEST PRIMARY ENERGY CONSUMER
OIL IS DOMINATING THE TRANSPORT SECTOR FAR INTO THE FUTURE
LIGHT VEHICLE CONSUMPTION IS STAGNATING IN SOME REGIONS, HEAVY DUTY PART IS GROWING
LIGHT DUTY VEHICLES IN THE EU ARE NEARLY STAGNATING FROM 2015
ENERGY EFFICIENCY IN THE USA 2030 STILL BEHIND OTHER REGIONS
LIGHT DUTY CONSUMPTION IN THE USA PEAKS IN 2015
CAN THE ADDITIONAL DEMAND FOR OIL BE SUPPLIED FROM THE PRESENT SOURCES?
OIL WILL BE THERE WHEN WE DON'T NEED IT FOR TRANSPORT ANY LONGER
ALL PRICE PREDICTIONS ARE WRONG
