Publication	2012.
Summary/Abstract	This article presents some of the main efficiency and fairness arguments in favor of open access publishing. It discusses how general open access could affect research and editorial practice. It ends with a discussion of the feasibility of open access and how a move to open access publishing could happen.

Economic feasibility of the path to zero net carbon emissions / DeCanio, Stephen J; Fremstad, Anders

Summary/Abstract

The United States and other developed countries currently and historically have transferred considerable resources overseas to further their foreign policy objectives and to purchase oil and natural gas. These transfers are comparable in magnitude to estimates of the scale of the economic effort that would be required to create a world-wide energy system with zero carbon emissions by the middle of this century. Solar energy, the most abundant of the alternative energy supply sources, is currently the most expensive of the alternatives to fossil fuels but a substantial body of research and practical experience suggests that solar costs could fall to competitive levels with sufficient technological progress and increases in solar energy production and capacity.

Summary/Abstract

The integration of hydropower facilities on existing low-head, non-Federal dams and their subsequent tie to regional electricity grids may serve as a useful de-centralized component of renewable energy integration in the United States. Thousands of low-head dams do not provide power and thus present few benefits with significant costs, including safety liability, fragmentation of river ecosystems, and persistent economic burden induced on state agencies due to regular inspection requirements. We conducted a feasibility study in the Piedmont region of North Carolina cataloguing over 1000 non-Federal dams with hydraulic head ranging from 4.6 m to 10.7 m (15 ft to 35 ft) and power capacity <300 kW ("micro" hydropower). Generation potential, greenhouse gas reductions, and financial viability were refined for 49 low-head dams over a 30-year life cycle using industry standard software (RETScreen4). Results suggest that most of these dams are not financially viable for energy production under cost structures evaluated at the time of this study. However, our results indicate that some low-head dams may be viable for energy production if provided funding opportunities comparable to the concurrent wind and solar markets.
