Since 2013，further development in new energy production other than oil and gas has continually contributed to the increase of domestic energy supply in the US，reducing the imported energy and oil dependence. And the United State of America could become an exporter of LNG in 2016. The U.S. democratic government maintained its consistent policy with an emphasis on clean energy to boost economic growth，reduce carbon emission and promote the environment protection. President Obama presented a low-carbon economic development strategy based on the rapid increase in natural gas production in his 2014 State of Union address.

With its rich oil，natural gas and other natural resources，Canadian government raised the idea of becoming an energy superpower in 2006，which involved how to promote further construction of oil pipelines，how to increase export of energy and diversify its export markets，and how to balance the development of energy economy，environment protection and conservation of traditional culture. Among them，how to achieve the balance，how to acquire the “social consent”，i.e. the consensus of supporting further energy exploitation from majority of population is the crucial factor for the future of Canada’s energy superpower dream.
