Given current high production levels, it isn’t clear whether reducing regulation and ending a pause on permitting for energy projects will actually boost the industry.

President Donald Trump announced on Monday he would declare a national energy emergency, with the goal of reducing costs for Americans. He said he would end a federal mandate on electric vehicles and the Green New Deal — seemingly in reference to climate policies by former President Joe Biden aimed at reducing fossil fuel consumption — but offered few other details in his speech.

Legal experts said the president was testing the boundaries of executive power with aggressive orders designed to stop the country from transitioning to renewable energy.
