Ahead of President Donald Trump's anticipated decision on the Paris Accord, energy stocks are in flux.

Peabody Energy  (BTU - Get Report) , the largest publicly traded U.S. coal company, and Cloud Peak Energy  (CLD) were both declining in early trading on Thursday. Notably, the two companies had asked the president to remain a part of the Paris Climate Agreement, Reuters reported.

Exxon's new CEO Darren Woods, who succeeded current U.S. Secretary of State Rex Tillerson, even penned a personal letter to the president addressing the matter, according to the Financial Times.

The Energy Select Sector SPDR Fund  (XLE - Get Report) , which holds Exxon, Schlumberger  (SLB - Get Report) , Halliburton  (HAL - Get Report) among others, was holding flat in pre-market trading.

On the other hand, Pattern Energy  (PEGI - Get Report) , which has a portfolio of wind power facilities, closed lower on Wednesday, while NextEra Energy  (NEE - Get Report) finished in the green as did Clean Energy Fuels  (CLNE - Get Report) .

Trump has campaigned on the promise to leave the deal. And, he will finally announce his decision at 3 p.m. EST in the White House Rose Garden.
