Petrol and Oil use fluctuated between 1980 and 1996 but then rose considerably up to today’s total of about 40 quadrillion units furthermore, it is predicted to increase to approximately 50 quadrillion units by 2030.  Natural Gas similarly fluctuated from 20 to about 23 units from 1980 until 2013 however, since then it has plateaued and is forecast to remain constant at 23 units until 2030.   

Coal use has risen steadily and is expected to continue growing up to 30 quadrillion units by 2030.  In contrast, a slight increase was witnessed in the growth of nuclear energy and Solar/Wind and they are estimated to reach 6 and 4 quadrillion units respectively by 2030.
