WASHINGTON - Oil and natural gas will continue to play a major role in America for years to come, even as the Biden administration seeks to conserve public lands and address climate change, President Joe Biden’s nominee to head the Interior Department pledges.Deb Haaland, a New Mexico congresswoman named to lead the Interior Department, said she is committed to "strike the right balance" as the agency manages energy development and seeks to restore and protect the nation's sprawling federal lands.Biden's agenda, including the possible creation of a Civilian Climate Corps, "demonstrates that America’s public lands can and should be engines for clean energy production" and "has the potential to spur job creation," Haaland said in testimony.
