Which is the more important headline?

US solar power nears competing on price (“US solar power will compete on price with conventional generation within three years without subsidy thanks to plummeting costs, industry leaders say.”)

Or:

Oil leaps as Opec descends into acrimony

Is a falling oil price a necessary concomitant of viable solar power on a large scale?  Or not?  Is the price of natural gas falling through the floor?  I missed that headline.

I thank Jim Olds for a relevant pointer.
