Shale energy production in the US has ushered in a new era of economic growth and, some say, has put this nation on the path to energy self-sufficiency.
But the same shale activity that acts as a domestic boon has not necessarily been beneficial for other nations, where our lessening dependence on their product is costing them much-needed oil revenue. This dynamic is especially worrisome in countries where oil and gas sales are their primary source of income. Nigeria and Angola – the No. 1 and No. 2 oil-producing nations in sub-Saharan Africa – have been especially hard hit.
