In the battle of big numbers at the first presidential debate, Mitt Romney used one five times to attack President Barack Obama’s energy policy: $90 billion.

That was the price tag of "breaks to the green energy world" Obama provided "in one year," Romney said.

Later, he elaborated the president had put that money "into solar and wind, to Solyndra and Fisker and Tesla and Ener1."

So, tens of billions funneled from the Obama administration to troubled companies for alternative energy — in one year. Really?

We asked the Romney campaign about that $90 billion.
