Australian households generate almost one-fifth of Australia's
greenhouse gases through everyday household
energy use and transport activities.
In fact, the average household in Australia emits over 8
tonnes of greenhouse gas each year solely through their
energy use. That's because most electricity comes from
burning coal and other fossil fuels.
One way you can help do this. Everyone can take action
to eliminate energy waste. It's easier than you think, and
the difference you can make is very surprising. Just by
being a little more aware about the way we use energy
each day, we can significantly reduce greenhouse gas
emissions, and cut our energy bills.
In Australia lighting currently represents 12 per cent of
greenhouse gas emissions from households. “Electric
lighting is a vital part of our lives but is still very inefficient.
We have been using incandescent light globes for 125
years and up to 90% of the energy each light bulb uses is
wasted, mainly as heat.”
A normal light globe is too hot to hold. – heat is wasted
and globally represents millions of tones of C02 that need
not be emitted into the atmosphere if we had used more
efficient forms of lighting.
These other forms of lighting such as the compact fluorescent
light bulb use around 20 per cent of the electricity to
produce the same amount of light. They can last between
4 and 10 times longer than the average incandescent light
bulb which can lead to major savings in household energy
costs very beneficial for your tenants. While they may be
more expensive to buy up front they can pay for themselves
in lower power bills within a year.

Tower & London 2008 Green Proposal
To avoid dangerous climate change we need to make
big cuts in emissions and we need to do it fast. This
means that individuals, organisations, governments
and business must act.
Tower & London would like to introduce to our clients
our plan for 2008 that we believe to be effective. We
plan gradually phase out inefficient light globes and
aim for replacing them with new energy efficient light
bulbs such as the compact fluorescent light bulbs
throughout each property.
We have entered into a long-term service agreement with a
licensed Electrician to perform the following every year.
1. Change all the incandescent lights to energy saving
lights.
2. Check all power points, ensure they are safe & working.
3. Replace the extractor bulb, if any. As it often blows.
4. Replace the smoke alarm battery are required by the
regulation & ensure the smoke alarm is working properly.
The cost will be:
• $100 plus GST every year, plus the cost of material such
as globes batteries and new power switches if necessary.
• Cost of light globes depending on the quality, availability
and discount seasons (8000 – 10000 Hrs $10-$15 approximately).
Not only tenants will be benefiting by cutting down their
electricity bills but you will also cut down your bills as
changing light bulbs, by law, is an owner’s responsibility.
Compare the difference between standard incandescent
light globes and compact fluorescent lights.

• Replacement of light bulbs is guaranteed for one year so
no labor or service charge will applicable to changing
light bulbs and smoke alarm batteries between
tenancies during the year (as in Kim’s article)
All properties with new low energy light fittings will
have special clauses in the lease ensuring the tenant
will purchase 100% renewable electricity.
All our landlords will be sent a letter detailing this
new service agreement for their consideration.
