Energy / Electricity
• Are Energy & Electricity the same thing?
• How much energy do we use in NSW?
• How much Electricity do we use in NSW?
• Energy Production - 2007 to 2008 3590PJ
• 1PJ = 9.93 million US gallons of LPG
• Energy Consumption - 2007 to 2008 1602PJ
• Electricity Generated – 2007-08 76,836 GWh = 276PJ
Energy / Electricity
The NSW Energy Demand is met by 8 primary sources
• Coal• Natural Gas• Hydro• Bagasse• Wind• Wood• Solar (Thermal & Photovoltaic)• Petroleum

Your Turn to do something
• Use the Multimeter to find the voltage and current of the solar panel
• This is called the open circuit voltage and current
• Rotate the panel to the sun and watch the voltage and current
• Now connect panels in series and parallel and test the voltage and current
• Using the wind turbine see what sort of voltage you can create

Woking Borough Council in the UK
• Allan Jones• Population – 100,000• Start date = 1990• Energy saved
– Energy consumption down by 44%– CO2 emissions down by 72%– Energy efficiency of housing up by 17%– First private wire network– District heating & cooling– Co & Tri generation

Sydney City Council
• 2030 plan• Employed Allan Jones• Facts
– To reduce greenhouse gas by 70% by 2030– Using energy efficiency programs ( Solar
panels etc)– Divert $2m spent on green power to energy
efficiency– Trigeneration
