# Producing energy from magnetic flux loops

I've simplified this down by quite a lot but as far as I understand it, magnetic fields on the Sun's surface twist together and when it gets all a bit too much they release energy.
My question is why can't we twist magnetic fields here on Earth to produce energy?

The very short answer: twisting a magnetic loop stores energy, it does not produce it. –  spencer nelson Jun 15 '11 at 20:34
