Cost of Electricity

Kilowatt hours, are a measurement of electrical usage, multiplied by whatever the utility company rates are.  Understanding this concept will go a long way to help you know where your energy dollars are going as well as provide a foundation for any future savings due to conservation.

 

Power consumption is measured in watts, volts multiplied by amperage equals watts which is usage.  The size of the appliance or duration of its use, both will effect power consumption.

 

Another way of looking at this; a 10KW solar array on the east coast, on average,  produces about 55 Kilowatt hours of energy per day.  At the average 9.5 cents a kilowatt hour you pay the power company, that would equate to $5.23 a day the 10 KW solar array could save you in energy payouts.

 

The data provided below should help to clarify normal electrical usage for an average size home, for one day!

Electrical Loads Hours Kilowatt Hours  Cost
(9) 100 watt light bulb 10 9 kilowatt hours .85
(1) 500 watt refrigerator 12 6 kilowatt hours .57
(1) 4500 watt water heater 03 13.5 kilowatt hours 1.28
(1) 5500 watt range 01 5.5 kilowatt hours .52
(1) 1500 watt washer 02 3 kilowatt hours .29
(1) 4500 watt dryer 02 9 kilowatt hours .76
(1) 2000 watt well pump 04 8 kilowatt hours 1.14
(2) 4800 watt central AC 06 58 kilowatt hours 5.51

Energy Management

Energy management is simply taking control of the amount of energy used; turning lights off for spaces not in use is a form of energy management. Management can be accomplished with automatic systems, setting load priority and maximum usage levels.  Heating and air conditioning type loads are generally the easiest to manage, and they make up the larger block of energy consumption. 

 

Today energy management is a popular topic of discussion and the technology is becoming part of all energy consuming appliances, lighting, and generator systems.

 

Until recently especially in the residential markets, implementation of adequately sized generator systems did not always occur.  This created bad potential scenarios for both the generator systems and the loads attached to the generator systems.  The need for a new electrical rule or standard, requiring load calculations for generator systems was recognized. 

 

Due to the cost associated with the installation of necessary larger generator  systems, needed to satisfy this new rule, manufacturers started utilizing energy management practices so as to minimize the generator system size and ultimately cost.  By load shedding at preset load levels, lower priority loads can be disconnected keeping connected demand to levels per the installed generator system.
