“The new approach could even pave the way for 100 percent self-sufficiency in power, heat, and water.”

A new report funded by the Dutch government finds that microgrid technologies could make a local “techno-economy” 90 percent self-sufficient, through the decentralized sharing of energy at the local level between multiple households.

This report adds fuel to efforts by the Siemens Corporation to design better microgrids and promote their efficiencies.

The new approach could even pave the way for “100 percent self-sufficiency in power, heat, and water, and 50 percent self-sufficiency in food production”, according to the report’s author, energy systems engineer Florijn de Graaf.
