Energy Storage and Renewable Energy [PDF]

open access: yesSSRN Electronic Journal, 2014
I consider an economy with fossil fuel and renewable energy and energy storage, and search for the conditions that lead to welfare improvements when energy is stored. I then solve for the optimal decision rule and analyze the long-run tendencies of the economy-energy variables. The findings are threefold.
