Groningeno lauke tradiciniai dujų gręžiniai sukelia žemės drebėjimus. O Jungtinėje Karalystėje žemės drebėjimus sukelia uolienų skaldymas dujų gavybai. Akmuo, iš kurio pašalintos dujos, susispaudžia, kaip kempinė, dėl ko kyla žemės drebėjimai net tokiose vietose, kur pastatai nepritaikyti žemės drebėjimams. [1]. Pigios dujos trukdo vėjo, saulės ir vandens energetikos įsitvirtinimui [2].
1. A Gas Cache, Now Under Shaky Ground
_The Groningen field was developed with traditional drilling techniques. But the geological problems posed even by a conventional gas field could provide additional fodder for critics of hydraulic fracturing technique, or fracking, which is being used elsewhere to extract gas from shale rock and has been known to cause minor earthquakes in Britain...
The gas is trapped in porous sandstone deep beneath the ground. When the fuel flows to the surface, the rock contracts like a squeezed sponge. In some places in the Groningen area, this contraction has caused the surface of what is already a low-lying area drained by numerous canals to sink as much as 35 centimeters, or nearly 14 inches. That has caused NAM to invest heavily in new water pumping stations and other water management systems._
2. News Analysis: The Potential Downside of Natural Gas
_Noting that natural gas was squeezing out some zero-carbon energy sources, Mr. Kimmell of the Union of Concerned Scientists said, “It would be a tremendous mistake to rely upon natural gas” to solve the climate problem [2]._
