Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

Energy Efficiency for Wastewater Treatment Plants

Energy Efficiency for Wastewater Treatment Plants

Much has changed in recent years in the water and wastewater industries: evolving environmental regulations, increasing oper­ating costs, technology advancements, and improved opportunities for load management, according to the Electric Power Research Institute (EPRI).

Job Site Support Equipment

Grading and excavating sites typically bring to mind big iron, but it also takes a lot of support equipment to complete a job—and even to begin one. The typical job site is home to job trailers for the foreman’s office long before utilities arrive. Trailers are filled with power-hungry systems.

Solar and Energy Storage Financing for Schools

Solar and Energy Storage Financing for Schools

Jason Coughlin, a solar analyst at the National Renewable Energy Laboratory, was coauthor of a 2011 report, “Solar Schools Assessment and Implementation Project: Financing Options for Solar Installations on K–12 Schools.”

“Schools have continued to install solar using power purchase agreements (PPAs) and the trend is to continue seeing third-party installations,” says Coughlin.
