You might find his PBS interview informative, though. I found that on the House website of Vermont Socialist, Bernie Sanders.
Here's a prime example:
"The United States could reduce its demand for energy by as much as 50% if only it would establish a federal agency large enough and forceful enough to impose rationing (on heating fuel as well as gasoline), allocate resources, rearrange the international oil market, set prices, raise taxes, issue energy stamps and redistribute income."
How do you like that?
