Optimizing Green Energy Systems

INFORMS Journal on Optimization
Energy production throughout the world is transitioning from fossil fuels to renewable sources such as wind power and solar power. This transition has been gradual—over half of the world’s electricity is still produced by coal, oil, and gas—but must accelerate to meet global emission targets.
