Electricity Usage

Conserving Electricity Usage Can Help Lower Your Utility Bill

Electricity usage is common in the form of non-energy consumption which utilizes electrical energy to power a machine or appliance. Electrical energy is typically the most used energy need created on an existing power supply. The electricity generated by power plants is normally sold to commercial and industrial users. With the increased number of power plants generating electrical energy, many countries have experienced a high demand for residential electricity.


As non-renewable energy,

electricity usage is measured in units called kWh per hour. Units of two per unit of the hour are used for comparison purposes. For instance, a home with a consumption rate of one thousand kWh per year would be considered ‘high-consumption by some utility companies. An average American household uses about forty-two thousand kWh per year. To put it in simple terms, the amount of energy needed to power the average American home is equal to about forty-two thousand watts per year.


Most homeowners

consume about twenty-five percent of their home’s electricity usage. This means that, on average, a family of four would use up about eleven thousand kilowatt-hours (kwh) in a year. To meet the utility company’s minimum requirements, a family would have to consume fifty-eight kilowatt-hours per month. Calculating this number by multiplying the percentage of kilowatt-hours consumed by the number of kilowatt-hours produced, we arrive at the amount needed to fulfill the utility company’s minimum requirement: E=Kcal. Using this calculation, it becomes clear that to meet the minimum requirement, a family would need to completely consume seventy-nine percent of its kilowatt-hours.


When combined with climate change considerations,

one might expect to see an increase in energy usage. Surprisingly, though, the amount of electricity used for air conditioning only slightly increases. This is because most air conditioning units are tuned for moderate temperatures and often compensate for higher temperatures by slowing down. For instance, an air conditioning unit may run at a maximum speed of thirty-two degrees, but slow down this speed to eighteen degrees and lower it again at the end of the day. Thus, while it may use more power to maintain a temperature of seventy-one degrees, the energy usage per degree remains the same.


When the unit is not running,

or “off”, it does not reduce the amount of electricity usage. This means that a family that has an air conditioner and a dryer can both use the same amount of energy at the same time. A family that purchases an energy star dryer may save money on their electric bill. The price of this machine is two to three times the cost of an energy star model for regular laundry, so families with electric bills are advised to consider purchasing an energy star dryer to save money on their electric bills. This small investment will pay off in savings over time, as dryers will take less energy to dry clothes and they will use fewer kilowatts to heat water.


Electric utility bill prices continue to rise,

as do the costs of utilities for all users. To conserve money and avoid increasing your utility bills, it is important to consider a combination of efficiency and green technologies to reduce your usage. A high-efficiency electric furnace may not be able to provide the cooling that you need daily, but it will be able to significantly reduce your electricity usage. Similarly, replacing your air conditioner with a more efficient model will lower your usage and use more kilowatts to achieve the same effect. If you replace all of your household appliances with more energy-efficient models, you can expect your utility bill to decrease.
