Examples of Energy Efficiency May Include:

Efficient lighting technologies or HVAC systems
Lighting and HVAC systems that can meet the same lighting or heating/cooling needs with less energy than previous systems.

Energy Star, LEED, or EarthCraft builders
Standards for building construction and/or energy and water usage developed by organizations interested in reducing the environmental impact of buildings.

Energy conservation to reduce energy consumption
Technologies and processes implemented to lower the amount of energy used. For example, occupancy sensor technology can turn off lighting, HVAC, and electronics in unoccupied rooms.

Developers of more efficient manufacturing processes
Methods which reduce energy use during the manufacturing of various products. For example, reorganizing production lines or simplifying tasks for factory workers.
