The energy sector continues to be a significant contributor to Canada’s economy. While renewables are becoming a more significant part of the global energy mix, fossil fuels will still provide a substantial portion of the world’s increasing energy demands for the foreseeable future even as there is an increasing focus on hydrogen, biogas and alternative energy sources.
The success of Canada’s energy sector has been built on entrepreneurship, innovation and the thoughtful management of the many challenges involved, including changing cost structures and commodity price fluctuations; evolving technology required to access previously stranded assets and improve carbon capture strategies; reducing carbon emissions and managing environmental impacts of operations; working in partnership with Indigenous groups; understanding the ever-evolving regulatory regimes; and working to obtain access to new markets.
