Correct but that means that no, we can't go all renewable right now. It actually means that when you add renewable, you're still about 70-80% dependent on natural gas (or coal) because of the very intermittent nature of solar/wind energy. And hydroelectric energy is (mostly, as some ecologist will protest) great but not scalable.
