Will Offshore Energy Face “Fair Winds And Following Seas”?: Understanding The Factors Influencing Offshore Wind Acceptance, Mario F. Teisl, Shannon K. Mccoy, Sarah J. Marrinan, Caroline L. Noblet, Teresa R. Johnson, Megan Wibberly, Sharon Klein
Publications
Most offshore energy studies have focused on measuring or explaining people’s perceptions of, and reactions to, specific installations. However, there are two different types of acceptance: one surrounds the siting of projects while the other surrounds a more general acceptance of offshore energy. Understanding what drives this second type of acceptance is important as governments have implemented new financial incentives and policies to support renewable energy development; however, citizens and government officials may be increasingly opposed to some of these support mechanisms. Our paper fills a void in the literature by using regression approaches to better understand how people’s evaluations …

Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz
Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz
Energy & the Environment
This paper estimates the renewable energy potential of Maine’s forest resources, and how much energy these resources could potentially provide the state. Using the most recent state-specific data available, and a methodology similar to the Billion Tons Report, we find that ethanol production from Maine’s forest residues could potentially provide 18% of Maine’s transportation (gasoline) fuels with a fermentation wood to ethanol process. Making Fischer-Tropsch diesel (F-T diesel) using forest residues can replace 39% of Maine’s petro-diesel consumption. Actual levels of biofuels that can be produced will depend on conversion factors and forestry residue removals that are subject to uncertainty.
