Here is an extract from our electricity bill. The coloured text has been added to highlight the rate, with the 'rate' being the price per kW.hr: We buy electrical energy at ENERGY RATE COST USED 92 Days 294.3 kWh 24.9000c $73.27 ENERGY RATE CREDIT PURCHASED (03/12/13 - 04/03/14) 92 Days 6.6000c 883.4 kWh $58.30 but we sell them (solar) electrical energy at Over the 92 days of this bill, what is the average rate at which the company supplied energy to this household? P =_ Watts. (Take the 92 days as 2 significant figures: the electricity meter is read by an employee whose time of reading could be at any time during the day.) Also, don't give an answer, but think about how many 'labourers' (using the example in the lesson) we would need to employ to provide energy at this average rate.
