It's actually kind of interesting. I think it might be helpful globally for clean energy. Cheap oil means people won't feel as much pain if a carbon tax is put in place to compensate for the externalities of using fossil fuels. So this is an opportunity for political movements in countries to push through a carbon tax now. Then when the price of oil goes back up (i.e. after OPEC has driven out the frackers and hurt Russia sufficiently), the carbon tax will make clean energy more competitive. I personally think that OPEC is shooting themselves in the foot over the long term with this move.
