Power Smart Colin’s house uses just 4 units of electricity a day because this veggie bed is also the air-conditioner! It also sells 4 units a day to the grid because there are PVs on the roof.

How to read my electric bill What’s the most important part to read?

In pairs, talk about your bills: Add up electric and gas units Do you think you use a little or a lot? 3

Household Energy Consumption WINTER High usage (per day) Medium usage (per day) Living Smart use (per day) Household size Energy electric + gas Water Energy electric+ gas 1-2 person 35 kwh 450 L 25 kwh 300 L 13 kwh 125 L 3-4 person 50 kwh 600 L 400 L 18 kwh 250 L 5+ person 70 kwh 750 L 45 kwh 500 L 22 kwh 375 L

What is a unit of electricity? 1 unit = 1 kWh = 1,000 watts of energy used for an hour (like a 1 bar electric fire, or 13 x 75w globes on for an hour)

What is a unit of electricity? Each unit of electricity causes 1 kg of greenhouse gas back at the power station 1 kg of greenhouse gas is enough to fill a ‘fit ball’

CO2 emission per capita per year per country Carbon footprint is a measure of the amount of carbon dioxide or CO2 emitted through the combustion of fossil fuels; in the case of an organization, business or enterprise, as part of their everyday operations; in the case of an individual or household, as part of their daily lives; or a product or commodity in reaching market. In materials, is essentially a measure of embodied energy, the result of life cycle analysis. A carbon footprint is often expressed as tons of carbon dioxide or tons of carbon emitted, usually on a yearly basis. There are many versions of calculators available for carbon footprinting. This is directly related to the amount of natural resources consumed, increasingly used or referred to as a measure of environmental impact. Carbon dioxide is recognized as a greenhouse gas, of which increasing levels in the atmosphere are linked to global warming and climate change.

Climate Change - Can we make a difference? Total Australian emissions = 559 million tonnes CO2e = 56 tonnes per household per annum. Car – 6 t Power – 6 t Gas – 1.5 t Water – 0.3 t Waste – 0.7 t Source: AGO Total – 14.5 tonnes per household Air travel, food, clothing, houses etc add another 16 tonnes.

So what’s ‘normal’?
