Fannie Mae HomeStyle Energy Mortgage

This paper discusses that the HomeStyle Energy mortgage loan is designed to support homeowners efforts to increase energy and water efficiency and reduce utility costs as well as create home resiliency for environmental disasters or to repair damage from such disasters. The document shows that HomeStyle Energy may be a more affordable financing solution than a subordinate lien, home equity line of credit, Property Assessed Clean Energy (PACE) loan, or unsecured loan.

Floating Photovoltaic Systems: Assessing the Technical Potential of Photovoltaic Systems on Man-Made Water Bodies in the Continental United States

This article concerns floating photovoltaic (FPV) systems, also called floatovoltaics, or aquavoltaics, a rapidly growing emerging technology application in which solar photovoltaic (PV) systems are sited directly on water. Along with providing such benefits as reduced evaporation and algae growth, it can lower PV operating temperatures and potentially reduce the costs of solar energy generation. This article provides the first national-level (United States) estimate of FPV technical potential using a combination of filtered, large-scale datasets, site-specific PV generation models, and geospatial analytical tools. The authors quantify FPV co-benefits and siting considerations, such as land conservation, coincidence with high electricity prices, and evaporation rates. Our results demonstrate the potential of FPV to contribute significantly to the U.S. electric sector, even using conservative assumptions.
