The debate over U.S. energy policy took a dramatic turn last month when Tesla Motors CEO Elon Musk squared off against the CEO top privately-owned U.S. coal producer Murray Energy.
In an interview for the CNBC show "Squawk Box," Robert Murray called Tesla and its electric cars a "fraud."
He criticized the automaker for failing to turn a profit even while receiving taxpayer subsidies.

Murray went on to say that closing every coal-fired power plant in the U.S. immediately "would not affect the temperature of the Earth at all."
Musk almost immediately fired back with, as is typical for him, a tweet.
He linked to the original CNBC video of the interview, and wrote that the "real fraud going on is denial of climate science."

In the original interview, Murray said Tesla had received "$2 billion from the taxpayer," and that the company has "not made a penny yet in cash flow."
After the interview aired, Tesla announced that it had earned a $22 million profit in the third quarter, its first profitable period since 2013.

Tesla has taken some government money, including a $465 million Department of Energy loan it paid back in 2013.
That loan was part of the Advanced-Technology Vehicle Manufacturing (ATVM) program, which offered loans to other companies, including established automakers Ford and Nissan.
Tesla buyers also qualify for a $7,500 federal tax credit, at least until the automaker hits a ceiling of 200,000 sales that will phase out the credit.

CNBC noted Energy Information Administration data showing that, in 2013, electricity production and federal utilities that rely on coal received $1.08 billion in direct cash outlays through federal programs, tax benefits, research and development funding, loans, and guarantees.
That amounted to 6 percent of such funding.
In comparison, electricity production from renewable-energy sources received $15.04 billion—or 72 percent of such funding—in the same year.

While he criticized Musk for taking subsidies, Murray also advocated for more government funding of so-called "clean-coal" technologies.
He said increased government subsidies for these technologies would create a "level playing field" with subsidized wind and solar power.
In December 2013, the Department of Energy did offer $8 billion in subsidies for projects to abate or reduce greenhouse-gas emissions from fossil fuels, including carbon capture and storage for coal-fired power plants, according to CNBC.
