Shale gas and a US manufacturing renaissance?

The shale gas advantage to the US remains to be seen, given that energy is internationally traded goods. If shale gas could make the US advantageous internationally, many countries could subsidise their energy sector too to the degree that the only advantage to the US is its intrinsic values of the shale gas.

How much is that relative to the size of the US economy, particularly in the international context when there are huge differences in labour costs even after taking account of differences in labour productivity?

Would that suggest a US manufacturing renaissance?

The answer is likely to be negative as long as a bit of simple reasoning is applied.
