This energy is often produced in not environmentally-friendly ways, like burning fossil fuels.
How technology reduces energy consumption:
Computer-controlled systems manage energy use
Solar panels reduce reliance on National Grid
Energy monitoring displays inform staff
LED's are low energy
Water conservation systems
Energy smart meters
