Review of PV Inverter Technology Cost and Performance Projections
The National Renewable Energy Laboratory (NREL) has a major responsibility in the implementation of the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program. Sandia National Laboratories (SNL) has a major role in supporting inverter development, characterization, standards, certifications, and verifications. The Solar Energy Technologies Program recently published a Multiyear Technical Plan, which establishes a goal of reducing the Levelized Energy Cost (LEC) for photovoltaic (PV) systems to 0.25-0.30 Wp by 2020. DOE determined the need to conduct a rigorous review of the PV Program's technical and economic targets, including the target set for PV inverters. NREL requested that Navigant Consulting Inc.(NCI) conduct a review of historical and projected cost and performance improvements for PV inverters, including identification of critical barriers identified and the approaches government might use to address them
Energy and the military: Convergence of security, economic, and environmental decision-making
Energy considerations are core to the missions of armed forces worldwide. The interaction between military energy issues and non-military energy issues is not often explicitly treated in the literature or media, although issues around clean energy have increased awareness of this interaction. The military has also long taken a leadership role on research and development (R&D) and procurement of specific energy technologies. More recently, R&D leadership has moved to the energy efficiency of home-country installations, and the development of renewable energy projects for areas as diverse as mini-grids for installations, to alternative fuels for major weapons systems. In this paper we explore the evolving relationship between energy issues and defense planning, and show how these developments have implications for military tactics and strategy as well as for civilian energy policy
