Tobias Brandt outlines how information technology (IT) can be used tointegrate sustainable energy technologies into existing infrastructures. Thetopic is approached from micro, meso, as well as macro perspectives. He firstdescribes how IT artifacts can be used to manage renewable energy sources andenergy storage devices in individual households and microgrids for an improvedeconomic and ecological performance. The author proceeds by assessing theeconomic feasibility of aggregating electric vehicles for large-scale energystorage. The final chapter explores the issue of stability in automatedmechanisms. A game-theoretical model is first introduced for financial marketsand later transferred to the automated management of energy demand.
