Former Vice President Al Gore was busy trolling President Trump on Twitter during the State of the Union address, slamming the idea of ending the war on energy as a farce.

"There is no war on American energy," Gore tweeted shortly after Trump announced the end of the war on American energy and the war on "clean, beautiful coal."

Instead, Gore said Trump should have showed support for solar jobs and other forms of clean energy.

"Doesn’t @RealDonaldTrump know that U.S. solar jobs are growing 17X the average job growth?" Gore asked.

Gore added that "America should lead on clean energy! Smart leaders are tapping into this unprecedented opportunity."

Trump recently approved new tariffs on solar panels imported into the United States in an attempt to jump start solar manufacturing domestically. However, most of the U.S. solar industry opposed the tariffs, which they warned Trump would erode 23,000 jobs after the first year of being enacted. The solar industry employs about a quarter of a million workers.

Gore is a top advocate on climate change. In 2017, he released the sequel to his 2006 climate documentary "An Inconvenient Truth." The sequel featured comments by then-candidate Donald Trump mocking the idea of climate change by saying on a cold day that the country could use some global warming.

Trump recently tweeted a similar statement during the December cold snap that ended in January with a weather event known as a bomb cyclone.

Trump tweeted that the U.S. “could use a little bit of that good old Global Warming that our Country, but not other countries, was going to pay TRILLIONS OF DOLLARS to protect against."

Anti-fossil fuel groups said the remarks "declared war on our climate," according to the group 350.org. "We won’t let him win."

“At a time when we need to be creating millions of good jobs in clean energy, Trump is doubling down on fossil fuels."
