Why the in­ter­est in shale gas?

Down to Earth - - COVER STORY -

THE GLOBAL energy mix, x, in the ab­sence of a strong cli­mate pol­icy, is likely to re­main highly fos­sil fu­elde­pen­dent. Ac­cord­ing too the In­ter­na­tional Energy Agen­cyency (IEA), even in 2035 aboutut 75 per cent of the energy de­mand will be met by y fos­sil fu­els. But within the fos­sil os­sil fu­els, IEA pre­dicts, the e share of coal and oil will re­ducece and that of gas, which is com­par­a­tively cleaner,ner, will in­crease in the nextt 20 years un­der the pres­suree to curb lo­cal pol­lu­tion and green­house en­house gases. The global de­mand for gas can in­crease by 50 per cent by 2035 com­pared to the 2010 level. The in­crease in gas de­mand will make many large coun­tries in­creas­ingly im­port-de­pen­dent. China's de­pen­dence on im­ported gas is likely to in­crease to 40 per cent by 2035; In­dia's to 45 per cent and the Euro­pean Union's to more than 80 per cent.

Much of the shale re­source ex­ists in coun­tries with lim­ited en­dow­ments of con­ven­tional oil and gas sup­plies, such as South Africa, Jor­dan and Chile; or in the coun­tries which­hich are net gas im­porters and face in­creas­ing im­port de­pen­dency, such as th the US and China; or in re­gions where con­ven­tional hy­dro­car­bon re­sources have largely been de­pleted, such as Europe. The ex­ploita­tion of shale gas is, there­fore, likely to re­duce prices and im­port de­pen­den­cies of coun­tries for nat­u­ral gas.
