New paper in JFM!
Wind turbines are reaching extreme sizes, with blades longer than football fields. Earth’s rotation affects wakes, impacting wind farm design/control. Coriolis effects yield wake deflections equivalent to ~20 degrees of yaw (wake steering).

The wind and solar siting locations that minimize the energy system cost differ significantly from the locations with the highest wind/solar resource potential on average.
While current renewable energy tax incentives in the U.S. reward total energy production – our results suggest that wind and solar complementarity and alignment with power demand can lead to a more cost-effective energy system design.
We design minimum-cost decarbonized energy systems in three regions (ISO-NE, CAISO, ERCOT). Using downscaled meteorological data at km-scale yields lower cost compared with typical meteorological data at resolutions over 30 km (i.e. reanalysis).
What resolution weather modeling do we need to guide renewables planning? How can we coordinate wind and solar siting to maximally benefit the grid?
Our new cover article in Cell Reports Sustainability answers these questions, led by Liying Qiu!

In this paper led by Postdoc Kerry Klemmer, we use LES to analyze wind turbine wake deficit and wake added turbulence kinetic energy in stable and neutral atmospheric boundary layers.
