|Turn down temperature setting on water heater||$0||$30-60|
|install low-flow shower head||$10 ||$15-50|
Units of Energy Measurement
Appliance energy use is measured in several ways:
- For electric appliances, watts, kilowatts, and kilowatt-hours are used. A kilowatt (1000 watts) is a measure of power, and tells you how fast a device uses energy when it runs. A kilowatt-hour (kWh) is a measure of energy actually used over time. Kilowatt-hours are what you pay for through your electric bill. To figure out how many kilowatt-hours of energy an appliance uses, you multiply the rate at which it uses energy (in kilowatts), times the number of hours it runs.
- For gas appliances, Btu's therms and ccf are used. Btu's are also used to rate the capacity of electric air conditioners and heat pumps. A Btu (British thermal unit) is approximately the amount of energy needed to raise one pint of water 1 degree F. The heating or cooling capacity of gas and oil water heaters, air conditioners and heat pumps, is rated in Btu's/hour. A therm is 100,000 Btu's of natural gas. Your gas meter measures your energy use in either therms or in ccf (hundred cubic feet of natural gas). A ccf of natural gas contains about one therm of energy.
What Do You Pay Now?
To find out how much you are currently paying for electricity, divide the total amount of your latest bill by the total number of kWh used. For natural gas, divide the bill amount by the total amount of ccf or therms used.
