Researchers survey the challenges of integrating wind and solar into power grids

As wind and solar power expand rapidly worldwide, researchers are confronting a growing challenge: how to effectively integrate them into the power grid. Wind turbines and solar panels have what economists call zero marginal cost, meaning producing additional units of electricity requires no fuel once installed. At the same time, this renewable energy varies greatly with the weather and can create operational challenges for grid operators.
