Unless there is something special about the area you are living in, I would suggest relocating to a new area. The Watt-Minder cannot help you.

It is a unit of work or energy equal to that done by one kilowatt of power acting for one hour. A kilowatt is 1,000 watts or 1.34 horsepower.

The amount of electricity used by ten 100-watt light bulbs left on for one hour. It is the measurement unit of consumption on your business electricity bill and charged on a pence per unit basis.

A kilowatt-hour is the unit by which residential and most business customers are billed for their monthly electric use. It represents the use of one kilowatt of electricity — or 1,000 watts — for one hour. For example, a 1,000-watt appliance, used for one hour, would use one kilowatt-hour of electricity. Similarly, a 100-watt light bulb, burning for 10 hours, also would use one kilowatt-hour of electricity.

A Kilowatt is a measure of power equaling 1,000 watts, describing the rate of energy use. For example, ten 100-watt light bulbs use one kilowatt of electricity.

Extensive – I’ve seen them listed as low as about $9/sq .ft. for 3” of growing media and sedums. More commonly the range is between $14 - $25/sq. ft., (including roofing membranes). But every project is unique, and certainly there are ways to lower the costs. Economy of scale is also very relevant. The Ford Motor Company River Rouge Plant greenroof in Dearborn, MI, for example, came in around $4/sq. ft.
