Shale gas could reshape the international energy landscape?

Shale gas development in the environmental impact can not be ignored. Experience from abroad, the environmental impact of shale gas  development mainly includes intensive water resources, water pollution, air pollution and ecological damage the surface.

Indeed, shale gas development in the environmental impact can not be ignored. Experience from abroad, the environmental impact of shale gas development mainly includes intensive water resources, water pollution, air pollution and ecological damage the surface.
        Shale gas, hydro-fracturing method of fracturing fluid mainly by high-pressure water, frac sand  and chemical additives. Drilling of shale gas on the one hand will consume a lot of surface water or groundwater, on the other hand in the hydraulic fracturing process, the chemicals may rise through the cracks from deep underground to the surface or shallow, it may be due to pipeline quality gas shale gas mining or improper operation caused by the leakage of chemical additives, which pollute rivers, lakes and groundwater. Cornell University researchers in the "Climate Science" magazine wrote that "shale gas production process, most of the resulting methane emissions into the atmosphere, rather than capture as fuel." In this regard, the United States Environmental Protection Agency in a report also acknowledged that "seriously underestimated the shale gas development in methane emissions."
     In addition, the use of  Hydraulic fracturing  of shale gas exploration, real estate stress may cause instability, giving rise to a series of minor earthquakes. France and the Bulgarian Government has released a ban on shale gas exploration using hydraulic fracturing method, which is tantamount to denying the current technical conditions of  shale gas  exploitation.
