What energy source is 100% privately funded and run as a profit-making business without federal funds/assisance?

I can't think of one.

When we get the sh!t out of our heads, and look BACK to nuclear power, we'll get a handle on energy independance. As long as we want to be sniveling NIMBY types about where the power plants and waste will go, we'll stay slaves to foreign oil.
