As light-emitting diode (LED) performance continues to improve and prices continue to drop, adoption continues to increase. According to the latest Department of Energy (DOE) Revolution…Now report, total installation of LED A-type bulbs (the most common type) exceeded 200 million last year, growing 160% over 2014, and now accounting for 6% of all currently installed A-type lamps. That growth has been enabled by a 94% reduction in cost since 2008.
Solar inverters are one of the most important components of a solar energy system. These power electronic devices convert the direct current produced by photovoltaic panels into alternating current – the type of electricity used by all of the appliances in your home. New technologies enable inverters to have advanced (smart) functions that serve to ensure the stability and reliability of the grid.

BASF Catalysts, a battery component manufacturer, is running the largest cathode materials manufacturing facility in the country with support from EERE’s Vehicle Technologies Office (VTO). The factory was supported by a $25 million American Recovery and Reinvestment Act project. Located in Elyria, Ohio, the facility at full capacity is capable of producing 2,500 metric tons per year of nickel-cobalt-metal cathode materials, a critical component of lithium-ion batteries.
Case study of a DOE Zero Energy Ready home in North Cape May, NJ, that scored a HERS 46 without PV or HERS 9 with 6.5 kW of PV. The two-story, 1,871-ft2 home has advanced-framed above-grade walls with R-21 fiberglass batt plus an R-3.6-insulated coated OSB sheathing, R-18 rigid-foam-insulated crawlspace walls, a cathedral ceiling insulated with 3 in. closed-cell spray foam plus R-30 fiberglass batt, solar water heating, a high-efficiency heat pump, an HRV, and mostly LED lighting.
