Mr. Gumerman will present on his recent work using a customized version of the National Energy Modeling System to examine the environmental and economic impacts of expanded and updated estimates of clean energy resources on Southern states. This modeling focused on aggressive energy efficiency, renewable policies, and possible legislation implementing a Renewable Portfolio Standard or a price on Carbon. Among the renewable resources, wind, biomass, and hydro are anticipated to provide the most generation potential. As the integration of renewable sources expands through the modeled time horizon, wind gradually out-competes biomass in the renewable electricity market. Cost-effective customer-owned renewables could also contribute significantly to electricity generation by 2030 in the South, under supportive policies.
