While the technologically advanced plants have attracted interest across the continent and in Europe and Asia, the current North American political situation has made long-term export planning difficult. Doug Murray, CEO of the Thunder Bay Community Economic Development Commission, says prospective biomass producers saw potential in exporting energy to . coal-producing communities along the Great Lakes. American energy producers had been inspired to look for alternatives to coal because of greenhouse-gas reduction targets contained in the . government’s Clean Power Plan. But the election of Donald Trump, who is an outspoken advocate of the coal industry, has thrown the regulatory demands into doubt. “The [Environmental Protection Agency] was going to dictate what they could do with their power. Now that’s come off. Now you have people saying, ‘Okay, which way is the future going?’” Murray says. “Legislative uncertainty is not an investment climate. Until people see direction, they’re going to wait.”
Many linguists join the Northwest and Northeast Caucasian languages into a North Caucasian family, sometimes simply called Kavkazian (in opposition to Kartvelian (South Caucasian) , which is thought to be unrelated, albeit heavily influenced by their northern neighbours). This hypothesis has perhaps been best illustrated by Sergei A. Starostin and Sergei Nikolayev , who present a set of phonological correspondences and shared morphological structure. However, there is no consensus that the relationship has been demonstrated, and many consider the correspondences to be spurious for the reasons mentioned above.
