My research focuses on the economics of renewable energy. To demonstrate feasibility and estimate cost of renewable electricity systems, researchers use computer models that calculate potential production from different technologies at each point in time, based on changing weather conditions. A model reveals which combination of electricity sources and energy storage systems has the lowest cost while always meeting demand.
Many studies demonstrate that fully renewable electric grids are feasible in the United States, Europe, Australia and elsewhere. My colleagues and I recently completed a small-scale study on the island-nation of Mauritius. Islands are attractive places for initial renewable transitions because of their small scale, relative simplicity and dependence on imported fuels.
