President Trump announced a handful of new energy initiatives Thursday as his administration wraps up a week in which officials tried to keep focus on their energy plans and achievements.

"For the past eight years, the federal government imposed masssive job-killing barriers to American energy development," Trump said in a speech at the Department of Energy headquarters.

The president touted the efforts his administration has made to roll back Obama-era environmental regulations and approve a pair of high-profile pipeline projects his predecessor stalled or blocked, the Dakota Access Pipeline and the Keystone XL Pipeline.

"Under the previous administration, so much of our land was closed to development, but we're opening it up," Trump said.

His initiatives included a plan to review ways to boost the nuclear energy sector and to build a pipeline that will pump petroleum south to Mexico.

"That'll go right under the wall, right?" Trump joked. "Have it go down a little deeper in that one section."

The White House has struggled to keep its policy-themed weeks in the headlines amid a special counsel investigation into Russian collusion allegations, a battle in the Senate over healthcare reform and the president's tendency to stray off-message on social media.

For "Energy Week," the administration held a press conference with Energy Secretary Rick Perry and highlighted Trump's decision to withdraw the U.S. from the Paris climate accords, something Trump cited as a well-received accomplishment during his speech on Thursday.

"When I go around, there are so many people that say, 'Thank you, you saved the sovereignty of our country,'" Trump said of his move to end American participation in the Paris deal.

The president also called attention to his efforts to revive the coal mining industry in the U.S., which he vowed repeatedly to do on the campaign trail.

"We have finally ended the war on coal," Trump said. "We are putting the coal miners back to work, just like I promised."
