Is solar power really cheaper than wind power?

摘要

For those of us out there who are part of the Renewable Energy story of this century, we have seen PV dropping from more than 4 US$/W to the current 0.9 US$/W or even less. This in a span of a bit more than ten years. Wind onshore on the other hand started on a remarkable 2 US$/W and moved quite fast to 1.5 US$/W being currently on the 1.2 US$/W or a bit below.
