Prices have increased by 45% in the past 4 years
Over the next 5 years the National Energy Regulator has approved 36% - 48% increase across the national grid.
Price increases over 10 years
Prices have increased by 85% in the past 10 years

ranks TOP 10 in the world worst polluting power plants!
• 92% of Victorias comes from Brown coal or lignite
• 8% is generated in a mix of renewables and gas
One tonne of coal burned =3 tonnes of emissions

Carbon tax and the end of the world as we know it!!!
The carbon tax would be a “wrecking ball” through the economy!
Shoulder • high demand on the ••network & at home- 9.00 am to 5.00 pm- 8.00 pm to 10.00 pm
Monday to Friday.
Peak/Off Peak• 16 hrs. Peak 7am – 11pm• 8 hrs. Off Peak 11pm - 7am
Understanding your energy billElectricity• calculated in kWh (kilowatt hours)• average Peak tariff 22 - 28 cents per kWh• average Off Peak tariff 10 - 16 cents per kWh• One kWh = 1000 watts consumed per hour.
Gas • calculated in Mj (Mega joule)• average tariff is 12 - 16 cents per Mj

Over 50% of our impact on emissions is generated from • the energy we buy
• the way we use it

Setting a higher temperature will heat your room faster
Quiz True or False
- Heating systems work at a fixed rate.
Setting a colder temperature on the air conditioner will cool your room faster?
- Cooling systems also work at a fixed rate.
False
False
Halogen down lights are low energy consumption because they are low voltage.
- Low voltage doesn’t mean low energy consumption
