What are some of the alternative, unconventional resources for oil and natural gas?
What will be an ideal response?
Both oil shale and oil sands (tar sands) are potential major and largely untapped resources for petroleum, and marine deposits of methane hydrate may have large supplies of natural gas. Oil shale and tar sands have not been cost effective until recently. Canada is now producing a major fraction of its petroleum from oil sands. Oil shale may become more economically attractive as conventional supplies are depleted and retail prices rise. The technology for safely extracting methane hydrate has yet to be developed. Methane is a potent greenhouse gas, and accidental release of large quantities might significantly increase global climate change.
