In the past few years, shale gas has surfaced as an alternative energy source due to considerable advancements in the technology of its extraction and exploration. Although this method has been in the news as a controversial form of extraction for energy, it is still a method that has seen increasing use, particularly in the United States.
Shale gas is produced from shale and is a natural gas. It has become a more widely used form of natural gas, however, there is some controversy as to the effects on the environment from extraction and use. Due to recent advancements, shale gas can now be extracted by hydraulic fracturing (fracking) and also horizontal drilling.
By far, Canada is the largest exporter of shale to the United States. The graph below illustrates that in Quarter 2 of 2011, we see the highest value of imports from Canada since Quarter 3 of 2008. Although there has been a large fluctuation in the import of shale, the overall trend is rising. As we continue to seek alternative energy sources, we will continue to see imports of shale.
