Financial industry giant Citigroup expects renewable energy ultimately will be triumphant but it needs fracked shale to get there.
David Roberts at the web site Grist writes: "The good news is that Citi expects renewable energy to triumph; it believes that typical forecasts like those from the International Energy Agency are too pessimistic. Contrary to a certain strain of conventional wisdom, it says, shale gas will not crowd out renewable energy. Quite the opposite.
"The pill? Citi expects it will take lots of natural gas — more than we’re currently using, in the medium term — to get to a power system run primarily on renewables. In fact, renewables and shale gas are in a “symbiotic” relationship, the report says, each helping the other increase market share. If that’s true, a moratorium on fracking, called for by many greens, might serve to inhibit the spread of renewable energy."
