U.S. wind-power installations dipped for the second consecutive year in 2017, thanks to tax policies aimed at boosting the use of clean energy.

Got that? Congress extended in late 2015 a key tax credit for wind. The new timeline let developers qualify for the full benefit with projects that begin construction by the end of 2016; the prior rule had applied to wind farms that began work by the end of 2014.
