Learn how to calculate savings of home energy improvementsJames Dulley
Energy-efficient products and services can cost more than conventional ones, but the electricity savings from energy-efficient measures should eventually offset their extra cost. To calculate the time it will take to break even on energy-efficient purchases, you need to know the product's type and...
There are several ways to calculate the power consumption of your high-wattage home appliances.The simplest way is to check the wattage specifications labeled on the device, in the manual, or on the manufacturer’s website.However, older or malfunctioning appliances may consume more than their ...
解析 The energy density is proportional to the square of the magnetic field strength, which is in turn proportional to the current flowing through the coiled wire, so the energy stored in the inductor must be proportional to I2.反馈 收藏 ...

Step 3: Using the equation Q=mL, calculate the energy required to change the substance from its first phase to its second phase. We can use the latent heat of fusion to calculate the energy required to melt the ice. This will be positive because the ice must take in...
Calculating Free Energy & Cell Potential Step 1:Identify the given values. Note: Depending on the requirement of the problem, proceed to Step 2 or Step 3 Step 2:Calculate Gibb's free energy of the cell using the expression, ΔG=nFE∘ ...
A similar measurement,heating degree day(HDD), reflects the amount of energy needed to heat a home or business. How to Calculate Cooling Degree Days (CDD) There are several ways to calculate CDD. The more detailed a record of temperature data, the more accurately the CDD can be calculated....
Calculate the yearly cost: In cellI9, enter the formula: =(($C$6/1000)*E9*F9)*365 PressEnter. Autofillthis formula. Note Use the absolute cell reference inC6as we do not wish to change the cell. Step 3 – Estimating Total Electricity Cost with the SUM Function ...
