Assessing the potential for renewable energy systems in remote arctic communities as a means of reducing regional diesel fuel dependence
The Arctic region faces many challenges related to combating the effects of climate change. Research has suggested that the region is overall more impacted by the rise in greenhouse gas emissions than other regions on Earth. More remote Arctic communities are dependent on fossil fuel sources, such …
