Part 4: Make a list of three energy efficient improvements you think could be made to a workplace. Describe what needs to be done (recommendations) and what changes and benefits they will bring to the workplace.
Energy Efficient Improvement Work Required Benefits To The Workplace
Power efficient light bulbs Replace all incandescent light bulbs with either ‘Compact Fluorescent Lamps’ (CFLs) or ‘Light Emitting Diodes’ (LEDs). CFLs only use around 20% of the relative energy as a common incandescent light bulb and last between four to ten times longer -

(1) Turn off electrical equipment/appliances when not in use and
(2) Use equipment/appliances with high Energy Rating Label

(1) Place stickers near light switches and office machines reminding people to turn them off when not in use. Over long breaks like Christmas, make sure all equipment, computers and appliances are turned off at the power point.
(2) Replace energy-intensive equipment/appliances with super-efficient models with high Energy Rating Label Energy conservation/saving due to reduced electricity consumption leading to reduction of energy bills.
