Nearly a month into the presidential transition, many questions about President-elect Trump's policies and cabinet remain unanswered, but one thing is clear: the federal oversight of energy, environment, and natural resources will be profoundly different under the Trump Administration. Early cabinet choices in financial services, the economy and international affairs suggest Trump is tracking to the center from his campaign positions. But not so for the energy sector. Likely appointments at the Departments of Interior, Energy, EPA and Agriculture have fundamentally different philosophies than do their Obama administration predecessors on virtually every issue, from energy development to environmental controls to climate change. Key appointments, policy announcements, and congressional hearings over the coming months will shape the new regulatory landscape for energy and natural resource developers.
