Projecting the urban energy demand for Indiana, USA in 2050 and 2080
Energy use is one of the largest drivers of climate change, but the large share of energy used for space heating and cooling mean that it is also driven by climate change. Demand for energy, particularly cooling, is important for long-range infrastructure planning. Urban areas represent a very small proportion of total land (0.72% in North America (Schneider et al 2009)), but usually consume the majority of energy. In this work statistical, top-down approaches are used to model residential and commercial urban energy demand changes in Indiana, a state in the Midwest region of the USA, in 2050 and 2080 under the climate change scenarios of RCP 4.5 and 8.5. By modeling energy demand changes in urban areas in Indiana, we can project the majority of energy demand while placing it in a spatial perspective that is missing from the statewide estimates. Two time periods are used to give an intuitive time stamp and temporal perspective. Results indicate that Indiana's northernmost cities are expected to show significantly increased residential cooling demand due to climate change by 2080. Indianapolis represents an increasing share of total urban commercial and residential energy use over the next 60 years. Transportation is expected to represent a larger share of energy use as heating demand declines under climate change scenarios.
