Does the President see this as kind of an arc, due to any overarching factors like decreased power of OPEC or dispersion of al Qaeda -- is there any -- are there any starting factors that the President sees crediting for this unrest?

WHITEHOUSE: Press Briefing

Despite all the talk of grid-based energy storage, the least expensive solution to the variability of wind and solar power is geographic dispersion, according to Leo Casey, Chief Technology Officer of Boston-based inverter company Satcon Technology, (NASD:SATC) speaking at the Building Energy 11 conference in Boston on March 9th.
