to reach nearly 42 quadrillion

in 2030. Natural gas and coal began at 20 and nearly 16

units

and despite some fluctuations, there will be a significant increase in coal to approximately 30

units

while

natural gas is predicted to stay the same after its slight growth. Even though nuclear, solar and hydropower consumed the same amount of energy in 1980, nuclear and solar will increase their use of power to nearly 8 and 5 quadrillion

units

respectively.

; hydropower will remain at the same level of consumption over the period.
