Australian Energy Use

(very old incomplete draft) How much energy does Australia consume and where is it used? According to the Australian Bureau of Statistics ABS, Australia used 5,525 petajoules (PJ) in 2004-2005. A Peta Joule is 1,000,000,000,000,000 Joules (which isn't that helpful is it?) 1 PJ is 1,000,000,000 MJ. 3.6 MJ is 1kWHr so 1 PJ is 278 Million kWHr. The transport sector (including household transport) is the largest end-user of energy, using 1,340 ... The manufacturing sector was the second highest user of energy (1,247 PJ ...). The transport and manufacturing sectors together accounted for 68% of total energy end-use. Domestic energy consumption is 433 PJ (electricity, gas, etc.) So, if we want to make a difference in terms of our energy consumption - and therefore CO2 emissions - shouldn't we focus on transport and manufacturing rather than
