Shale gas

Shale gas, a form of natural gas found in shale deposits, is abundant globally, especially in Asia and North America. Its extraction involves hydraulic fracturing, a complex process requiring significant water and chemicals, which poses environmental risks such as water contamination and methane emissions. Despite these concerns, shale gas extraction is widespread in the US and Canada and is growing in China, Australia, and Europe.
