The U.S. coal industry has seen a dramatic shift in the past year.
The number of coal-fired power plants in the U.P. has grown by more than half since 2009.
In recent years, the industry has also seen a resurgence in its sales of power from natural gas.
The coal industry employs more than 100,000 people in the United States.
It produces more than 60 percent of the country’s electricity.
Coal production has boomed in recent years.
Coal is the dominant fuel used in electricity generation and is responsible for nearly half of the nation’s total greenhouse gas emissions.
President Donald Trump has called the coal mining industry a “sad” industry and is working to curtail it.
His administration has been trying to slash regulations on coal mining and other industries.
But Trump’s efforts have not been successful, according to a new report from the Center for American Progress.
In his first 100 days, Trump has not moved to reduce the nation.
In January, the White House released a draft plan to reduce emissions by 20 percent by 2025, but that plan was shot down by a Democratic senator.
The administration has also proposed several changes to federal rules on coal ash disposal.
Despite the efforts of the Trump administration, coal mining is still the nations largest source of greenhouse gas pollution.
“The coal-mining industry has become a major contributor to the nationís climate change problem,” said Andrew Wheeler, an energy researcher at the Center, in a statement.
For the past several years, coal mines have been on a steep decline.
Between 2005 and 2016, the number of mines in the country declined by about half.
Between 2011 and 2015, the total number of miners declined by more the same amount.
And by 2021, the coal-burning industry was estimated to be losing nearly 50,000 jobs in the industry, according the Energy Department.
However, the Trump White House has not been able to bring down the coal burning industry, Wheeler said.
Trump has proposed cutting the coal production and exports ban by one-fifth, which would put more than 1 million coal miners out of work.
And he has threatened to impose a 45 percent tariff on Chinese imports of American coal.
