After a detailed exploration of the reasons for the current increase in oil production capacity, with much more coming after 2020, Maugeri warns that the oil industry will need to work hard to limit environmental risks from greatly expanded drilling for oil (and natural gas) in shale deposits, a vast resource that has been made tappable by hydraulic fracturing, known also as fracking.

The International Energy Agency has issued a report that is essential reading for anyone interested in ensuring that the global boom in gas production facilitated by hydraulic fracturing, or fracking, is carried out with environmental integrity.

The Post Carbon Institute's latest report exposes inflated predictions by the Energy Information Administration of how much oil and gas is accessible by hydraulic fracturing that have led to local government officials relaxing restrictions on the fracking industry.

Last year, the paper reports, 30 percent of power in the U.S. came from natural gas, up from 19 percent in 2005, driven by hydraulic fracturing and horizontal drilling that have unlocked large and inexpensive new supplies of the fuel.
