Shale gas: One country's meat is another country's poison?

Shale gas offers an alternative to oil in the energy consumption mix of a country and its industries such as steel, power generation, petrochemicals and transportation.

Global reserves of shale gas (208 trillion cubic meters) are allocated in a fairest manner than reserves of conventional gas but production enjoyed a rapid takeoff only in the US, boosted by its law on subsoil property.

The take-off of US production has already reduced the energy bill of US companies ($11bn since 2010) and

raised their relative competitiveness.

This also means higher (relative) energy costs elsewhere, especially in Europe, as portability remains challenging.

The risk of accelerated shale gas extraction is the possible contamination of surrounding soils.
