Topic 4: Sustainable work practices
Skills Practice Title: Reducing waste and energy use in current work practices
Procedures:
Part A – Determining ways of reducing the amount of waste produced due to current work
practices
2.1. Through observation, list the types of waste typically produced as a result of the
current workplace practices.
2.2. Classify the waste products into recyclable and non-recyclable.
2.3. Determine the extent to which the waste products are recyclable. That is, by
observation of the quantities of waste, identify whether the larger portion of it is recyclable
or non-recyclable.
2.4. Identify the waste products that are produced in the greatest quantity (can be
recyclable or non-recyclable).
2.5. By observation of current work practices, determine how to reduce the quantity of
some or all of the waste products. For example, are some waste products recyclable, but
are not being recycled? Can waste be reduced by changing current work practices, such
as reducing the amount of electrical cable being discarded by keeping the off-cuts for
future use in other work projects?
Record your Observations

Part B – Determining ways of reducing the amount of energy used
2.1. Identify the types of non-renewable energy sources currently used in the workplace,
including electrical energy, oil products (petrol, diesel) and gas. Assume the electrical
energy being consumed is from non-renewable sources.
2.2. By referring to workplace records and accounts, determine which type of energy
source is used the most in the workplace.
2.3. Identify the extent to which the workplace uses energy from renewable sources. For
example, does the workplace make use of the sun’s energy through good use of
insulation and windows to keep the workshop temperature stable and to avoid using
artificial lighting?
2.4. Identify and describe ways energy could be reduced through current work practices.
For example, by turning the power off to lighting and equipment that is not being used, by
fitting lamps that are more energy efficient, by changing the layout of the work area, or by
keeping windows and doors closed to keep the workshop temperature stable and to avoid
using heaters or air conditioners.

Topic 5: Sustainable energy
Skills Practice Title: Reducing energy use at worksite/home
Part A – Determining amounts and patterns of electrical energy usage
2.1. Obtain a recent electrical energy bill for your home or worksite. If possible obtain
several bills. From these documents, determine the amount of electrical energy used (in
kilowatt hours) over the billing period. Refer to other bills to determine if the energy used
varies between seasons. (Some energy companies provide graphs of energy usage
over different periods.)
2.2. Determine if electrical energy use increases during a particular season. For
example winter, or maybe summer.
2.3. Identify, from observation, how others in your home/worksite use electrical energy
in terms of sustainability.
2.4. Where electrical energy usage varies between seasons, identify one or more
reasons. For example, air conditioners used in summer, gas heating in winter.
Record your Observations
Part B – Determining ways of reducing the amount of energy used
2.1. By looking at name plates or manufacturer’s information, identify those commonly
used items of electrical equipment in your home/worksite that consume more than 200
watts of power. Examples include refrigerators, heaters, air conditioning units, stoves,
many power tools and some types of entertainment equipment.
2.2. Examine the type of lighting in the premises and identify the type of lamps that are
mainly used. These could be fluorescent tubes, incandescent lamps, LED lamps etc. Also
examine how the lighting is used by others. Note particularly if incandescent lamps are on
for long periods.
2.3. Identify appliances that are greater than say 10 years old, and determine whether
new models on the market have a higher efficiency. For example, refrigerators and
washing machines, and other items that are required to show an energy (star) rating.
2.4. Identify and describe ways energy could be reduced through improved energy usage
practices. For example, by turning lights off when not in use, increasing the amount of
natural light to reduce lighting usage, wearing warmer or cooler clothing to minimise use
of heaters or air-conditioners.
2.5. Identify appliances and types of lighting that could be replaced with higher efficiency
types. For example, air conditioning units, refrigerators and freezers. Identify also where
energy efficient lamps could be used while still retaining the same light level.

provided.
3.2 Summarise your findings and give suggestions on ways to reduce electrical energy
use in the home/worksite. For example, through changed energy usage practices,
replacing or servicing electrical equipment, changing to different types of lighting. Add
anything else you can think of that helps reduce electrical energy use.
