In this article, the author explains that the peak Victorian electricity demand during the heatwave in 2014 didn't exceed the previous record set in 2009 because:

 What is the total capacity, in GW, of coal fired capacity that has been retired to date?

Which state currently has no coal fired generators, but used to have brown coal fired units?

AEMC is considering a rule change to allow networks to charge PV owners to export onto the grid.  The logic behind this is:

Read the executive summary in the report from the Australian Energy Market Operator

A solar hot water system receives 12.8kWh/day (4kWh/m2 on a 4m2 system with 80% efficiency).  How many litres of water will that heat up by 55 degrees (heat capacity of 4.18 J/K/g)?

Assume there are 1.1 million rooftop solar hot water systems, each with 4m² surface area, receiving 4kWh/m2/day and absorb 80% of the solar energy.  Averaged over the course of the day, how much  power (in MW) will this generate?

Same wall as question 2, but now with addition of insulation, the thermal conductivity has been reduced to 0.3W/m²K.  Now how much heat is flowing (10m², 20⁰C gradient)? Include the units

 A brick wall with an area of 10m² and a thermal conductivity of 5W/m²K is experiencing a temperature gradient of 20⁰C (hotter outside than inside).  How much heat will be flowing through the wall? Be sure to include the units.
