White House Adviser John Podesta knocked environmentalists Wednesday for their ridiculous adherence to “green” energy and their criticism of natural gas.

Podesta made the remarks to a group of reporters during a discussion at the White House.

“If you oppose all fossil fuels and you want to turn that switch off tomorrow, that is a completely impractical way of moving toward a clean-energy future,” Podesta said. “With all due respect to my friends in the environmental community, if they expect us to turn off the lights and go home, that’s sort of an impractical suggestion.”

Podesta is the former president of the liberal think tank Center for American Progress, making his comments all the more surprising.

But really, it's just common sense: As much as environmentalists would like to stop using fossil fuels immediately and switch to wind, solar and unicorn burps, it's just not possible.

Podesta's remarks came one day after environmental groups told President Obama that exporting natural gas would undermine global warming initiatives.
