Hello Dan,

Roughly speaking all of the components of a solar storm have the same energy with an order of magnitude or two. The thermal part of a solar flare contains about 10^22 Joules, the energy in accelerated electrons is 10^21 to 10^25 Joules, the energy in the accelerated protons is about 10^21 to 10^25 Joules, and the kinetic energy of the coronal mass ejection is also about 10^24 Joules.

As a reference, the power consumption of the United States in a whole year is about 10^20 Joules. So the energy released in a large solar storm is about 100,000 year worth of power for the US.

Cheers - David
