Logistics of getting land-based wind turbines to sites could delay or cancel installations and risk up to $2.1 billion in revenue, an energy consultant study reports.

The energy industry is in transition on nearly every level.

The 600MW Rush Creek Wind Project will be home to 300 turbines and an 83-mile transmission line near Limon, Colo.

With several large, grid-scale battery-storage facilities opening in quick succession in Southern California, pundits say the state has taken a leading role in developing infrastructure to hold renewable power generated during low-demand periods, using it to supply customers during peak hours.

Renewable generation is expected to account for about two-thirds of the 24 GW of energy capacity the U.S. added in 2016, and industry observers don’t expect alternative-energy additions to fall in coming years, despite changed political winds.
